Let T be the statement: The sum of any two rational numbers is rational. Then T is true, but the following "proof is incorrect. Find the mistake. "Proof by contradiction: Suppose not. That is, suppose that the sum of any two rational numbers is not rational. This means that no matter what two rational numbers are chosen their sum is not rational. Now both 1 and 3 are 1/1 and 3 3/1, and so both are ratios of integers with rational because 1 a nonzero denominator. Hence, by a supposition, the sum of 1 and 3, which is 4, is not rational. But 4 is rational because 4 4/1 , which is a ratio of integers with a nonzero denominator. Hence 4 is both rational and not rational, which is a contradiction. This contradiction shows that the supposition is false and hence statement T is true.
Answer:
the mistake is in the first statement.
Explanation:
Now lets us put the statement into consideration:
"The sum of any two rational numbers is irrational"
The negation is: " there exists a pair of rational numbers whose sum is irrational". (Existence of at least one of such a pair).
The negation is not "the sum of any two rational numbers is irrational"
Therefore the mistake is in the first statement and it is due to incorrect negation of the proof.
What is the solubility of an empty soda can
Answer:
Around 2.2 grams.
Explanation:
2.2 g CO2∗1 mol CO244 g CO2=0.05 mol
355 mL∗1 L1000 mL=0.355 L
So here we can see we have about 0.05 mol/0.355 L or about 0.14 mol of carbon dioxide per liter of soda. Of course this value varies by manufacturer, type of drink, container, etc.

A standard core of rules or specification is beneficial because ____.
A. all programmers involved in with a product can follow the same guidelines
B. A variety of styles is the best for the final part
C. Everyone’s code style is followed
D. Style changes with different subject matter
The correct answer is
A standard core of rules or specification is beneficial because all programmers involved in with a product can follow the same guidelines .
Other options are not correct because a variety of styles is not prefered and used in software development, and everyone's code style can not be followed easily. Because programming style changes with different programmers, so it would not easy for other programmer to read and understand the code.
Two Smallest (20 points). Write a program TwoSmallest.java that takes a set of double command-line arguments and prints the smallest and second-smallest number, in that order. It is possible for the smallest and second-smallest numbers to be the same (if the sequence contains duplicate numbers). Note: display one number per line. Hint: Double.MAX_VALUE is the largest real number that can be stored in a double variable. java TwoSmallest 17.0 23.0 5.0 1.1 6.9 0.3 0.3 1.1 java TwoSmallest 1.0 35.0 2.0 1.1 6.9 0.3 0.3 6.7 0.3 0.3

import java.util.*;
public class Main {
public static void main(String args[]) {
int n;
Scanner input = new Scanner(System.in);
n = input.nextInt();
double nums []= new double [n];
for (int i=0; i<n;i++)
{
nums[i] = input.nextDouble();
}
Arrays.sort(nums);
System.out.println("The two smallest are: ");
for (int i=0; i<2;i++)
{
System.out.println(nums[i]);
}
}
}
Explanation:
This line declares number of input
int n;
This line calls the Scanner function
Scanner input = new Scanner(System.in);
This line gets input from user
n = input.nextInt();
This line declares an array of n elements
double nums []= new double [n];
The following iteration gets input into the array
for (int i=0; i<n;i++)
{
nums[i] = input.nextDouble();
}
This line sorts the array
Arrays.sort(nums);
The following iteration prints the two smallest
System.out.println("The two smallest are: ");
for (int i=0; i<2;i++)
{
System.out.println(nums[i]);
}
12. Write C statement(s) that accomplish the following. a. Declare int variables x and y. Initialize x to 25 and y to 18. b. Declare and initialize an int variable temp to 10 and a char variable ch to 'A'. c. Update the value of an int variable x by adding 5 to it. d. Declare and initialize a double variable payRate to 12.50. e. Copy the value of an int variable firstNum into an int variable tempNum. f. Swap the contents of the int variables x and y. (Declare additional variables, if necessary.) g. Suppose x and y are double variables. Output the contents of x, y, and the expression x 12 / y - 18. h. Declare a char variable grade and set the value of grade to 'A'. i. Declare int variables to store four integers. j. Copy the value of a double variable z to the nearest integer into an int variable x.
Answer:
a.
int x = 25;
int y = 18;
b.
int temp = 10;
char ch ='a';
c.
x += 5;
d.
double payRate = 12.5;
e.
int tempNum = firstNum;
f.
int tempp = x;
x = y;
y = tempp;
g.
printf("Value of x = %f\n",x);
printf("Value of y = %f\n",y);
printf("Arithmetic = %f\n",(x + 12/y -18));
h.
char grade = 'A';
i.
int a,b,c,d;
a = 5; b = 2; c = 3; d = 6;
j.
int x = round(z);
Explanation:
The answers are straight forward.
However, I'll give a general hint in answering questions like this.
In C, variable declaration is done by:
data-type variable-name;
To declare and initialise the variable, you do;
data-type variable-name = value;
So, for questions that requires that we declare and initialise a variable, we make use of the above syntax..
Take (a) for instance:
int x = 25;
int y = 18;
Same syntax can be applied to (b), (d), (e), (h) & (I)
For question (c);
This can be done in two ways;
x = x + 5;
Or
x+=5;
Both will give the same result.
For question (f):
We start by initialise a temporary variable that stores x.
Then we store the value of x in y.
Then we store the content of the temporary variable to y.
This swaps the values of x and y
For question (g):
When printing a double variable in C, we make use of '\f' as a string format
For question (j):
The round function is used to round up a double variable to integer.

The input begins with an integer indicating the number of integers that follow. You can assume that the list will have at least 2 integers and less than 20 integers. Ex: If the input is: 5 10 5 3 21 2 the output is: 2 3 To achieve the above, first read the integers into an array. Hint: Make sure to initialize the second smallest and smallest integers properly. 265236.1527390
Answer:
Here is the C++ program:
#include <iostream> //to use input output function
#include <vector> //to use vectors
using namespace std; //to identify objects like cin cout
int main() { //start of main method
int size, number; //to store size of list and input numbers
cout<<"Enter list size: "; //prompts user to enter size of the list
cin >> size; //reads list size from user
vector<int> v; //creates a vector named v
for (int i = 0; i < size; ++i) { //iterates till the size of list reaches
cin >> number; //reads the input numbers
v.push_back(number); } //push number into a vector from the back
int num1 = v[0], num2 = v[1], current , temp; //num1 is set to the element at 0-th position of v and num2 is set to be on 1st index of v
if (num1 > num2) { //if num1 is is greater than num2
temp = num1; //assigns value of num1 to temp
num1 = num2; //assigns value of num2 to num1
num2 = temp; } //assigns value of temp to num2
for (int i = 2; i < size; ++i) { //iterates size times
current = v[i]; //set current to the i-th index of v
if (current < num1) { //if current is less than num1
num2 = num1; //assigns value of num1 to num2
num1 = current; } //assigns value of current to num1
else if(current < num2) { //if value of current is less than num2
num2 = current; } } //assigns value of current to num2
cout<<num1<< " "<<num2<< endl; } //dispalys num1 and num2 i.e. two smallest integers in ascending order
Explanation:
I will explain the program with an example.
Lets say the list size is 4 and numbers are 1 2 3 4
for (int i = 0; i < size; ++i)
This loop reads each number (1,2,3,4) and adds that number to the vector v which is the sequence container. The method push_back is used which inserts each number into the vector at the end, after the current last number and the vector size is increased by 1.
Next num1 = v[0] becomes num1 = 1
and num2 = v[1] becomes num1 = 2
if (num1 > num2) this condition is false so program moves to the statement:
for (int i = 2; i < size; ++i)
current = v[i]; becomes current = v[2]; which is current = 3
if (current < num1) is false so program moves to :
else if(current < num2) this is also false.
So the program moves to the statement:
cout<<num1<< " "<<num2<< endl;
which prints these two numbers 1 and 2 on output screen as the two smallest integers in the list in ascending order. Hence the output of the program is:
1 2
The screenshot of output of the program is attached.

Given four values representing counts of quarters, dimes, nickels and pennies, output the total amount as dollars and cents. Output each floating-point value with two digits after the decimal point, which can be achieved as follows: System.out.printf("Amount: $%.2f\n", dollars); Ex: If the input is: 4 3 2 1 where 4 is the number of quarters, 3 is the number of dimes, 2 is the number of nickels, and 1 is the number of pennies, the output is: Amount: $1.41 For simplicity, assume input is non-negative.
LAB ACTIVITY 2.32.1: LAB: Convert to dollars 0/10 LabProgram.java Load default template. 1 import java.util.Scanner; 2 3 public class LabProgram 4 public static void main(String[] args) { 5 Scanner scnr = new Scanner(System.in); 6 7 /* Type your code here. */|| 8 9) Develop mode Submit mode Run your program as often as you'd like, before submitting for grading.

Answer:
Replace /* Type your code here. */ with the following lines of code
int quarter =scnr.nextInt();
int dime = scnr.nextInt();
int nickel = scnr.nextInt();
int penny = scnr.nextInt();
double dollars = quarter * 0.25 + dime * 0.1 + nickel * 0.05 + penny * 0.01;
System.out.printf("Amount: $%.2f\n", dollars);
System.out.print((dollars * 100)+" cents");
Explanation:
The next four lines declare the given currencies as integer
int quarter =scnr.nextInt();
int dime = scnr.nextInt();
int nickel = scnr.nextInt();
int penny = scnr.nextInt();
This line calculates the amount in dollars
double dollars = quarter * 0.25 + dime * 0.1 + nickel * 0.05 + penny * 0.01;
The next two lines print the amount in dollars and cents respectively
System.out.printf("Amount: $%.2f\n", dollars);
System.out.print((dollars * 100)+" cents");
Given four values representing counts of quarters, dimes, nickels and pennies, the total amount in dollars and cent can be represented as follows;
#1 quarters = 0.25 dollars
#1 dime = 0.1 dollar.
#1 nickel = 0.05 dollars
#1 penny = 0.01 dollars
#quarters, dimes, nickels and pennies,
x = input("write your input here: ")
for i in x:
quarters = 0.25*float(x[0])
dime = 0.1*float(x[1])
nickel = 0.05*float(x[2])
penny = 0.01*float(x[3])
sum1 = quarters + dime + nickel + penny
print(round(sum1, 2))
Code explanation:The commented section of the code is just the conversion rate of quarters, dime, nickel and penny to dollars.

Write a function index(elem, seq) that takes as inputs an element elem and a sequence seq and returns the index of the first occurrence of elem in seq. The sequence seq can be either a list or a string. If seq is a string, elem will be a single-character string; if seq is a list, elem can be any value. If elem is not an element of seq, the function should return the length of the sequence. Dont forget that the index of the first element in a sequence is 0. Here are some examples: >>> index(5, [4, 10, 5, 3, 7, 5]) solution
Answer:
def index(elem, seq):
for i in range(len(seq)):
if elem == seq[i]:
return i
return len(seq)
print(index(5, [4, 10, 8, 5, 3, 5]))
Explanation:
Create a function named index that takes elem and seq as parameters
Create a for loop that iterates through the seq. If elem is equal to the item in the seq, return the i, index of the item.
If the elem is not found in the seq, this means nothing will be returned in the loop, just return the length of the seq, len(seq)
Call the function with given parameters and print the result
Note: Since 5 is in the list in the example, the index of the 5 which is 3 will be returned
In this exercise we have to use the knowledge of computational language in Python, so we have that code is:
It can be found in the attached image.
What is an index in Python?An index, in your example, refers to a position within an ordered list. Python strings can be thought of as lists of characters; each character is given an index from zero to the length minus one.
So, to make it easier, the code in Python can be found below:
def index(elem, seq):
for i in range(len(seq)):
if elem == seq[i]:
return i
return len(seq)
print(index(5, [4, 10, 8, 5, 3, 5]))

functions, which are presented in the form of?
A. Text labels
B. Webpages
C. Buttons and menus
Answer:
The answer to this question is given below in the explanation section.
Explanation:
The correct answer to this question is B.
Because different browsers perform similar functions that are presented in the form of webpages. If you want to run the webpage in chrome, it will run similarly as you run it in internet explorer or in firefox.
However, other options such as text labels and buttons and menus are not the browser functions because these are the elements of the webpages.
