Answer:
Baselines
Explanation:
The idea of software configuration management is that of monitoring and controlling changes in the software. The baseline is the standard and formally accepted form of a software item that is meant to be configured. It is like a generally accepted reference point, which could be applied in effecting incremental changes in the software.
There are three types of baselines which are the functional, developmental, and product baselines. Functional baselines provide an overview of the functionality and specifications of a system. The product baseline encompasses both the functional and physical details of the system.
Teachers in most school districts are paid on a schedule that provides a salary based on their number of years of teaching experience. For example, a beginning teacher in the Lexington School District might be paid $30,000 the first year. For each year of experience after this first year, up to 10 years, the teacher receives a 2% increase over the preceding value. Write a program that displays a salary schedule, in tabular format, for teachers in a school district. The inputs are:
Answer:
Here is the python code:
StartingSal = int(input("Enter the starting salary: "))
AnnualIncrease = (int(input("Enter the annual % increase: ")) / 100)
Years = int(input("Enter the number of years: "))
for count in range(1,Years+1):
print("Year ", count, " Salary: ", StartingSal*((1+AnnualIncrease)**(count-1)))
Explanation:
This program prompts the user to enter starting salary, percentage increase in salary per year and number of years.
The for loop has range function which is used to specify how many times the salaries are going to be calculated for the number of years entered. It starts from 1 and ends after Years+1 means one value more than the year to display 10 too when user inputs 10 days.
The year and corresponding salary is displayed in output. At every iteration the starting salary is multiplied by annual percentage increase input by user. Here count is used to count the number of salaries per year, count-1 means it will start from 30000.
Which tab group is used to modify the background of a chart that is contained in a PowerPoint presentation?
Chart styles
Data
Type
Chart layouts
Answer:
Chart styles
Explanation:
In PowerPoint, once you have inserted a chart (e.g a bar or pie chart), the format tab would be enabled so that you can format your chart to your taste. In this format tab, there are a bunch of tab groups such as:
(i) Chart styles: This allows you to typically change the component background colors of your chart.
(ii) Data: This contains sub-tabs that allow you to edit and select the data on your chart.
(iii) Type: This contains sub-tabs such as "Change Chart Type" which will allow you to change the type of the chart. For example if you were using a pie chart and you want to change it to a bar chart or any other chart, you can do that here.
(iv) Chart Layouts: This allows to change or modify how the selected chart is laid out.

How many levels can be returned in a single query?
Answer:
One.
Explanation:
In this case, when a developer writes a SOQL query in order to find to find child records for a specific parent, one search will return only one child. One level down i.e., from parent to child, or five levels up i.e., from child to parent. Note that SOQL statements will not return relationships that are greater than one level apart from the root entity object.

Explanation:
Use the loop invariant (I) to show that the code below correctly computes the product of all elements in an array A of n integers for any n ≥ 1. First use induction to show that (I) is indeed a loop invariant, and then draw conclusions for the termination of the while loop.
Algorithm 1 computeProduct(int[ ] A, int n)
p = a[0]
i = 0
while i < n − 1 do
//(I) p = a[0] · a[1] · · · a[i] (Loop Invariant)
i + +
p = p · a[i]
end while
return p
Answer:
Given Loop Variant P = a[0], a[1] ... a[i]
It is product of n terms in array
Explanation:
The Basic Step: i = 0, loop invariant p=a[0], it is true because of 'p' initialized as a[0].
Induction Step: Assume that for i = n - 3, loop invariant p is product of a[0], a[1], a[2] .... a[n - 3].
So, after that multiply a[n - 2] with p, i.e P = a[0], a[1], a[2] .... a[n - 3].a[n - 2].
After execution of while loop, loop variant p becomes: P = a[0], a[1], a[2] .... a[n -3].a[n -2].
for the case i = n-2, invariant p is product of a[0], a[1], a[2] .... a[n-3].a[n-2]. It is the product of (n-1) terms. In while loop, incrementing the value of i, so i=n-1
And multiply a[n-1] with p, i.e P = a[0].a[1].a[2].... a[n-2].
a[n-1]. i.e. P=P.a[n-1]
By the assumption for i=n-3 loop invariant is true, therefore for i=n-2 also it is true.
By induction method proved that for all n > = 1 Code will return product of n array elements.
While loop check the condition i < n - 1. therefore the conditional statement is n - i > 1
If i = n , n - i = 0 , it will violate condition of while loop, so, the while loop will terminate at i = n at this time loop invariant P = a[0].a[1].a[2]....a[n-2].a[n-1]

Alcatel-Lucent was founded in 1919, it was a French global telecommunications equipment manufacturing company with its headquarter in Paris, France. Alcatel-Lucent provide services such as telecommunications and hybrid networking solutions deployed both in the cloud and on properties.
Alcatel-Lucent’s High Leverage Network (HLN) increases bandwidth and network capabilities while reducing the negative impact on the environment. This high leverage network can handle large amounts of traffic more efficiently because the networks are intelligent and send packets at the highest speed and most efficiently. HLN are intelligent such that it delivers increased bandwidth using fewer devices and energy.
Generally, when the High Leverage Network (HLN) is successfully implemented, it helps telecommunications companies to improve their maintenance costs, operational efficiency, enhance network performance and capacity to meet the bandwidth demands of their end users.
Availability is an essential part of ________ security, and user behavior analysis and application analysis provide the data needed to ensure that systems are available. baseline infrastructure applications network
Answer:
Network.
Explanation:
Availability is an essential part of network security, and user behavior analysis and application analysis provide the data needed to ensure that systems are available.
Availability in computer technology ensures that systems, applications, network connectivity and data are freely available to all authorized users when they need them to perform their daily routines or tasks. In order to make network systems available regularly, it is very essential and important to ensure that all software and hardware technical conflicts are always resolved as well as regular maintenance of the systems.
A network administrator can monitor the network traffics and unusual or unknown activities on the network through the user behavior analysis and data gathered from the application analysis to ensure the effective and efficient availability of systems.
Use the following cell phone airport data speeds (Mbps) from a particular network. Find P10. 0.1 0.1 0.3 0.3 0.3 0.4 0.4 0.4 0.6 0.7 0.7 0.7 0.8 0.8
Answer:
[tex]P_{10} =0.1[/tex]
Explanation:
Given
[tex]0.1, 0.1, 0.3, 0.3, 0.3, 0.4, 0.4, 0.4, 0.6, 0.7, 0.7, 0.7, 0.8, 0.8[/tex]
Required
Determine [tex]P_{10}[/tex]
[tex]P_{10}[/tex] implies 10th percentile and this is calculated as thus
[tex]P_{10} = \frac{10(n+1)}{100}[/tex]
Where n is the number of data; n = 14
[tex]P_{10} = \frac{10(n+1)}{100}[/tex]
Substitute 14 for n
[tex]P_{10} = \frac{10(14+1)}{100}[/tex]
[tex]P_{10} = \frac{10(15)}{100}[/tex]
Open the bracket
[tex]P_{10} = \frac{10 * 15}{100}[/tex]
[tex]P_{10} = \frac{150}{100}[/tex]
[tex]P_{10} = 1.5th\ item[/tex]
This means that the 1.5th item is [tex]P_{10}[/tex]
And this falls between the 1st and 2nd item and is calculated as thus;
[tex]P_{10} = 1.5th\ item[/tex]
Express 1.5 as 1 + 0.5
[tex]P_{10} = (1 +0.5)\ th\ item[/tex]
[tex]P_{10} = 1^{st}\ item +0.5(2^{nd} - 1^{st}) item[/tex]
From the given data; [tex]1st\ item = 0.1[/tex] and [tex]2nd\ item = 0.1[/tex]
[tex]P_{10} = 1^{st}\ item +0.5(2^{nd} - 1^{st}) item[/tex] becomes
[tex]P_{10} =0.1 +0.5(0.1 - 0.1)[/tex]
[tex]P_{10} =0.1 +0.5(0)[/tex]
[tex]P_{10} =0.1 +0[/tex]
[tex]P_{10} =0.1[/tex]
Explain ways that computer-related errors are associated with the people using those computers. Contrast that with errors made by the computer systems directly.
Answer and Explanation:
Computer related errors associated with people that use these computers are errors that are made by human beings in instructing(or programming) the computer to do or complete a certain task. This could involve such things as moving paper based data to the computer(electronic data) where the human could enter incorrect data or inconsistent programs or code.
Computer related errors which directly have to do with the computer consist of error thrown by the system as a result of ineffective code or software related issues or faulty hardware. In either case all computer related errors are inherently caused by humans since a computer would only take instruction given to it.
A large population of ALOHA users manages to generate 50 requests/sec, including both originals and retransmissions. Time is slotted in units of 40 msec.
Required:
a. What is the chance of success on the first attempt?
b. What is the probability of exactly k collisions and then a success?
c. What is the expected number of transmission attempts needed?
Answer:
The answer is below
Explanation:
Given that:
Frame transmission time (X) = 40 ms
Requests = 50 requests/sec, Therefore the arrival rate for frame (G) = 50 request * 40 ms = 2 request
a) Probability that there is success on the first attempt = [tex]e^{-G}G^k[/tex] but k = 0, therefore Probability that there is success on the first attempt = [tex]e^{-G}=e^{-2}=0.135[/tex]
b) probability of exactly k collisions and then a success = P(collisions in k attempts) × P(success in k+1 attempt)
P(collisions in k attempts) = [1-Probability that there is success on the first attempt]^k = [tex][1-e^{-G}]^k=[1-0.135]^k=0.865^k[/tex]
P(success in k+1 attempt) = [tex]e^{-G}=e^{-2}=0.135[/tex]
Probability of exactly k collisions and then a success = [tex]0.865^k0.135[/tex]
c) Expected number of transmission attempts needed = probability of success in k transmission = [tex]e^{G}=e^{2}=7.389[/tex]
You are a project manager for Laredo Pioneer's Traveling Rodeo Show. You're heading up a project to promote a new line of souvenirs to be sold at the shows. You are getting ready to write the project management plan and know you need to consider elements such as policies, rules, systems, relationships, and norms in the organization. Which of the following is not true? A These describe the authority level of workers, fair payment practices, communication channels, and the like. B This describes organizational governance framework. C This describes management elements. D This is part of the EEF input to this process.
Answer:
A. These describe the authority level of workers, fair payment practices, communication channels, and the like.
Explanation:
As seen in the question above, you have been asked to write the project management plan and know that you need to consider elements such as policies, rules, systems, relationships and standards in the organization. These elements are part of EEF's entry into this process, in addition they are fundamental and indispensable for the description not only of the organizational governance structure, but also describe the management elements that will be adopted and used.
However, there is no way to use them to describe the level of authority of workers, fair payment practices, communication channels and the like, as this is not the function of this.

Similar to Wi-Fi, ____ is designed to provide internet access to fixed locations (sometimes called hot zones), but the coverage is significantly larger
Answer:
WiMAX.
Explanation:
WiMAX is an acronym for Worldwide Interoperability for Microwave Access, it is a wireless communications which is primarily based on the IEEE 802.16 standards for creating Metropolitan Area Network (MAN) for the internet users.
Similar to Wi-Fi, WiMAX is designed to provide internet access to fixed locations (sometimes called hot zones), but the coverage is significantly larger.
WiMAX is capable of covering large metropolitan distance of several kilometers while Wi-Fi covers just a local (short) area measured in meters.
Generally, WiMAX was invented by the WiMAX forum and is a telecommunications standard protocol that provides fixed and fully mobile internet access services over a wide range.
How many times does the following loop execute? double d; Random generator = new Random(); double x = generator.nextDouble() * 100; do { d = Math.sqrt(x) * Math.sqrt(x) - x; System.out.println(d); x = generator.nextDouble() * 10001; } while (d != 0); exactly once exactly twice can't be determined always infinite loop
Answer:
The number of execution can't always be determines
Explanation:
The following points should be noted
Variable d relies on variable x (both of double data type) for its value
d is calculated as
[tex]d = \sqrt{x}^2 - x[/tex]
Mere looking at the above expression, the value of d should be 0;
However, it doesn't work that way.
The variable x can assume two categories of values
Small Floating Point ValuesLarge Floating Point ValuesThe range of the above values depend on the system running the application;
When variable x assumes a small value,
[tex]d = \sqrt{x}^2 - x[/tex] will definitely result in 0 and the loop will terminate immediately because [tex]\sqrt{x}^2 = x[/tex]
When variable x assumes a large value,
[tex]d = \sqrt{x}^2 - x[/tex] will not result in 0 because their will be [tex]\sqrt{x}^2 \neq x[/tex]
The reason for this that, the compiler will approximate the value of [tex]\sqrt{x}^2[/tex] and this approximation will not be equal to [tex]x[/tex]
Hence, the loop will be executed again.
Since, the range of values variable x can assume can not be predetermined, then we can conclude that the number of times the loop will be executed can't be determined.
A byte addressable direct-mapped cache has 1024 blocks/lines, with each block having eight 32-bit words. How many bits are required for block offset, assuming a 32-bit address
Answer and Explanation:
"The inquiry as presented is not necessarily responsible. A word has been states as 32-bit. We need to ask if the frame is "byte-addressable" (From this we can access to get an 8-bit piece of information) or "text-addressable" (the smallest open lump is 32-bit) or maybe "half-word-addressable" (the tiny bundle of information it could reach to 16-bit).
To understand what the smallest request bit of a position is to let anyone know, you have to remember this.
You operate from base up at that stage. We will agree with the byte-addressable structure. Every reserved square at a certain point contains 8 words * (4 bytes/word) = 32 = 25 bytes, so the counterbalance seems to be 5 bits.
The history in a direct-mapped stored is the squares in reserves (12 bits for this position due to 212 = 4096). at a certain point, as you have seen, the tag is also one of the bits left behind.
As the reserve becomes increasingly cooperative. And a similar size remains. These are lesser bits on the list and more bits on the mark.'
What is industry 4.0 -automation revolution-, what is your opinion about the direction this revolution is taking the industry in, and discuss the fate of unskilled and semi-skilled workers affected by industry 4.0.
Answer:
Find the explanation below.
Explanation:
1. Industry 4.0 -automation revolution is a term first used in Germany in 2011 to describe the fourth generation of the industrial revolution. It is the incorporation of digitalized procedures that use smart technology that can work in real-time to industrial production. This means that the machines used in production can independently interact between themselves to accomplish tasks that would otherwise have needed human involvement.
2. My opinion regarding this industrial revolution is that it is a welcome development for businesses because it will help them execute projects at faster rates and limit some working expenses.
3. Unskilled and Semi-skilled workers will be badly affected by this revolution because tasks ordinarily performed by them would be mostly taken over by these machines. This means that companies would most likely lay off these workers whose jobs would now be performed by machines. Job regulation agencies would do well to seek ways to intervene for this group of workers. They may also have to improve their skills if they want to remain relevant to their jobs.
The revolution, however, would be favorable for high-skilled workers because they would be needed to perform jobs such as the maintenance and programming of these machines.
A Fast Critter moves twice as fast as a regular critter. When asked to move by n steps, it actually moves by 2 * n steps. Implement a Fast Critter subclass of Critter whose move method behaves as described.
Answer and Explanation:
The code:
FastCritter.java
Public class FastCritter
{
public static void main(string[]args)
{
Critter DoubleFast = new FastCritter();
DoubleFast.move(10);
System.out.println(DoubleFast.getHistory());
system.out.println(" the critter object will move to 20]");
}
}
in the above, the critter class is assumed to have been defined and the the object DoubleFast which moves twice the distance of the Critter was achieved by using the move method which was defined in the critter class. The move method takes the position of the Critter and adds the steps given to its parameter to the object's move thus getting twice the distance. The get history is assumed to get the history of positions and moves made by the object in an array as defined in the class
A cache has been designed such that it has 512 lines, with each line or block containing 8 words. Identify the line number, tag, and word position for the 20-bit address 94EA616 using the direct mapping method.
Answer:
Given address = 94EA6[tex]_{16}[/tex]
tag = 0 * 94 ( 10010100 )
line = 0 * 1 D 4 ( 111010100 )
word position = 0*6 ( 110 )
Explanation:
using the direct mapping method
Number of lines = 512
block size = 8 words
word offset = [tex]log ^{8} _{2}[/tex] = 3 bit
index bit = [tex]log^{512}_{2}[/tex] = 9 bit
Tag = 20 - ( index bit + word offset ) = 20 - ( 3+9) = 8 bit
Given address = 94EA6[tex]_{16}[/tex]
tag = 0 * 94 ( 10010100 )
line = 0 * 1 D 4 ( 111010100 )
word position = 0*6 ( 110 )
What is the value of the variable named myNum after the statements that follow are executed? var myNum = 14; var yourNum = 4; myNum++; yourNum-- myNum = myNum * yourNum;
Answer:
45
Explanation:
Initially, myNum is equal to 14 and yourNum is equal to 4
Then, myNum is incremented by 1 and becomes 15
Also, yourNum is decremented by 1 and becomes 3
Finally, myNum is set to myNum x yourNum, 15 x 3 = 45

Oops, we made a mistake: we created a key "short" and gave it the value "tall", but we wanted to give it the value "long" instead. Write the line of code that will change the value associated with the key "short" to "long". Be consistent in whether you use single or double quotes to declare your strings: our autograder assumes you'll be consistent.
Answer:
Using java
//assuming that hashmap object name is ChangeMap
ChangeMap. replace("short", "long");
System.out.println("New HashMap: "
+ ChangeMap.toString());
Explanation:
From the above we have used the replace method to replace the value of the "short" key in the hashtable with "long" instead of the previous value "tall". We have used the printed the hashtable to the console using println and the ".toString()" method that we added to the function's parameter.

Write a method named removeDuplicates that accepts a string parameter and returns a new string with all consecutive occurrences of the same character in the string replaced by a single occurrence of that character. For example, the call of removeDuplicates("bookkeeeeeper") should return "bokeper" .
Answer:
//Method definition
//Method receives a String argument and returns a String value
public static String removeDuplicates(String str){
//Create a new string to hold the unique characters
String newString = "";
//Create a loop to cycle through each of the characters in the
//original string.
for(int i=0; i<str.length(); i++){
// For each of the cycles, using the indexOf() method,
// check if the character at that position
// already exists in the new string.
if(newString.indexOf(str.charAt(i)) == -1){
//if it does not exist, add it to the new string
newString += str.charAt(i);
} //End of if statement
} //End of for statement
return newString; // return the new string
} //End of method definition
Sample Output:
removeDuplicates("bookkeeeeeper") => "bokeper"
Explanation:
The above code has been written in Java. It contains comments explaining every line of the code. Please go through the comments.
The actual lines of codes are written in bold-face to distinguish them from comments. The program has been re-written without comments as follows:
public static String removeDuplicates(String str){
String newString = "";
for(int i=0; i<str.length(); i++){
if(newString.indexOf(str.charAt(i)) == -1){
newString += str.charAt(i);
}
}
return newString;
}
From the sample output, when tested in a main application, a call to removeDuplicates("bookkeeeeeper") would return "bokeper"
Assume userName equals "Tom" and userAge equals 22. What is displayed in a dialog box when the following statement is executed? alert(userAge + " \nis " + userName + "'s age.");
Answer:
22
is Tom's age.
Explanation:
Since userAge is initialized as 22, 22 will be displayed in a line. Then, since there is a "\n" which means go the new line, the program will display in the new line. is will be displayed. Since userName is initialized as Tom, Tom will be displayed. Then 's age. will be displayed in the same line.
There is a colony of 8 cells arranged in a straight line where each day every cell competes with its adjacent cells(neighbour). Each day, for each cell, if its neighbours are both active or both inactive, the cell becomes inactive the next day,. otherwise itbecomes active the next day.
Assumptions: The two cells on the ends have single adjacent cell, so the other adjacent cell can be assumsed to be always inactive. Even after updating the cell state. consider its pervious state for updating the state of other cells. Update the cell informationof allcells simultaneously.
Write a fuction cellCompete which takes takes one 8 element array of integers cells representing the current state of 8 cells and one integer days representing te number of days to simulate. An integer value of 1 represents an active cell and value of 0 represents an inactive cell.
Program:

I am not able to get the error and I think my logic is wrong. Can we apply dynamic programming here If we can then how?
Answer:
I am writing a C++ program using loops instead of nested if statements.
#include <iostream> // to use input output functions
using namespace std; // to identify objects like cin cout
void cells(int cells[],int days){ /* function that takes takes one array of integers cells, one integer days representing the number of days to simulate. */
int pos ,num=0; //declares variables pos for position of two adjacent cells and num to iterate for each day
int result[9]; //the updated output array
while (num< days) { //this loop keeps executing till the value of num is less than the value of number of days
num++;
for(pos=1;pos<9;pos++) //this loop has a pos variable that works like an index and moves through the cell array
result[pos]=(cells[pos-1])^ (cells[pos+1]); //updated cell state determined by the previous and next cells (adjacent cells) by bitwise XOR operations
for(pos=1;pos<9;pos++) //iterates through the array
cells[pos]=result[pos]; } //the updated cells state is assigned to the cell array simultaneously
for(pos=1;pos<9;pos++) //iterates through the array and prints the resultant array that contains the updated active and inactive cells values
cout << result[pos]; }
int main() { //start of the main function body
int j,day;
int output[9];
*/the two cells on the ends (first and last positions of array) have single adjacent cell, so the other adjacent cell can be assumed to be always inactive i.e. 0 */
output[0]=output[9]=0;
for(j=1;j<9;j++) //takes the input array from user
cin >> output[j];
cin >> day;
cells(output,day); } //calls the function cells to print the array with active and inactive cells states.
Explanation:
The program is well explained in the comments mentioned with every statement of the program. I will explain with the help of example:
Suppose the user enters the array = [1,0,0,0,0,1,0,0] and days=1
The while loop checks if the value of num is less than that of days. Here num is 0 and days is 1 So this means that the body of while loop will execute.
In the body of while loop the value of num is incremented by 1. The first loop initializes a variable pos for position of adjacent cells. The statement is a recursive statement result[pos]=(cells[pos-1])^ (cells[pos+1]) that uses previous state for updating the state of other cells. The “^” is the symbol used for bitwise exclusive operator. In bitwise XOR operations the two numbers are taken as operands and XOR is performed on every bit of two numbers. The result of XOR is 1 if the two bits are not same otherwise 0. For example XOR of 1^0 and 0^1 is 1 and the XOR of 0^0 and 1^1 is 0. The second for loop update the cell information of all cells simultaneously. The last loop prints the updated cells states.
The main function takes the input array element from user and the value for the days and calls the cells function to compute the print the active and inactive cells state information.
The screenshot of the program along with its output are attached.
Some systems analysts maintain that source documents are unnecessary. They say that an input can be entered directly into the system, without wasting time in an intermediate step.
Do you agree? Can you think of any situations where source documents are essential?
Answer:
The summary including its given subject is mentioned in the portion here below explanatory.
Explanation:
No, I disagree with the argument made by 'system analyst' whether it is needless to preserve source records, rather, therefore, the details provided input would be fed immediately into the machine. Different source document possibilities can be considered may play a significant role in accessing data.Assumed a person experiences a problem when collecting and analyzing data that has no complete access or that individual is not happy with the system or that may want comprehensive data search. However, a need arises to keep data both sequentially and fed further into the desktop system that would help us through tracking purposes.Even with all the documentation that has been held is essentially for the user to do anything efficiently and conveniently without even any issues and 'device analyst' would guarantee that it has been applied in a very well-defined way.Explain why it is not necessary to create an inbound rule on the internal 192.168.12.10 Windows server so that it can receive the response (ICMP echo reply) from the internal 192.168.12.11 Windows server.
Answer:
The file and printer sharing (Echo Request - ICMPv4-In) rule option should be listed for all profile.
Explanation:
The main reason why it is not compulsory or obligatory to design an inbound rule on the internal 192.168.12.10 Windows server in other to be able to accept the response (ICMP echo reply) generated from the internal 192.168.12.11 Windows server is that the file and printer sharing (Echo Request - ICMPv4-In) rule option or alternative needed to be listed for all profile.
Inbound rules filter or sieve traffic advancing from the network to the local computer based on the filtering conditions set out in the rule.
#Imagine you're writing some code for an exercise tracker. #The tracker measures heart rate, and should display the #average heart rate from an exercise session. # #However, the tracker doesn't automatically know when the #exercise session began. It assumes the session starts the #first time it sees a heart rate of 100 or more, and ends #the first time it sees one under 100. # #Write a function called average_heart_rate. #average_heart_rate should have one parameter, a list of #integers. These integers represent heart rate measurements #taken 30 seconds apart. average_heart_rate should return #the average of all heart rates between the first 100+ #heart rate and the last one. Return this as an integer #(use floor division when calculating the average). # #You may assume that the list will only cross the 100 beats #per minute threshold once: once it goes above 100 and below #again, it will not go back above.
Answer:
Following are the code to this question:
def average_heart_rate(beats):#defining a method average_heart_rate that accepts list beats
total=0 #defining integer variable total,that adds list values
count_list=0#defining a count_list integer variable, that counts list numbers
for i in beats:#defining for loop to add list values
if i>= 100:#defining if block to check value is greater then 100
total += i#add list values
count_list += 1# count list number
return total//count_list #return average_heart_rate value
beats=[72,77,79,95,102,105,112,115,120,121,121,125, 125, 123, 119, 115, 105, 101, 96, 92, 90, 85]#defining a list
print("The average heart rate value:",average_heart_rate(beats)) # call the mnethod by passing value
Output:
The average heart rate value: 114
Explanation:
In the given question some data is missing so, program description can be defined as follows:
In the given python code, the method "average_heart_rate" defined that accepts list "beats" as the parameter, inside the method two-variable "total and count_list " is defined that holds a value that is 0.In the next line, a for loop is that uses the list and if block is defined that checks list value is greater then 100. Inside the loop, it calculates the addition and its count value and stores its values in total and count_list variable, and returns its average value.
