The distribution of the number of transactions per day at a certain automated teller machine (ATM) is
approximately normal with a mean of 80 transactions and a standard deviation of 10 transactions. Which of
the following represents the parameters of the distribution?
ī=80; s = 10
B
I = 80; 92 = 10
I = 80; o = 10
D x = 80; o = 10
Ei=80; 8 = 10
Answers
Answer:
ī=80; s = 10
Step-by-step explanation:
When the standard deviation is from a finite group it is denoted by s. The number of transactions from an atm are countable in a day. So the standard deviation will be represented by s.
and ī represents the mean.
The other choices are incorrect because mean is usually represented by a bar over the alphabet such as x.
a simple alphabet does not denote the mean of the sample or population.
Parameters are the characteristics used to define a dataset.
The representation of the parameters are: [tex]\bar x = 80[/tex] and [tex]s = 10[/tex]
From the question, we have:
[tex]Mean = 80[/tex]
[tex]Standard\ Deviation = 10[/tex]
Mean is represented as: [tex]\bar x[/tex]
So, we have:
[tex]\bar x = 80[/tex]
Standard deviation is represented as [tex]\sigma[/tex] of s.
So, we have:
[tex]s = 10[/tex]
Hence, the representation of the parameters are:
[tex]\bar x = 80[/tex] and [tex]s = 10[/tex]

The measure of angle ∠ZTB of triangle SRT is 31°.
What is a triangle?A triangle is a flat geometric figure that has three sides and three angles. The sum of the interior angles of a triangle is equal to 180°. The exterior angles sum up to 360°.
For the given situation,
Let S R T be a triangle, and point Z is the in center of triangle S R T.
Lines are drawn from point Z to the sides of the triangle to form right angles and line segments Z A, Z B, and Z C as shown in the below figure.
Here, ∠ AZR = 35°, ∠ZRC = 35°, ∠ BSZ = 24°, ∠ZSA = 24°, ∠ZTB = ?
The in center of a triangle is the intersection point of all the three interior angle bisectors of the triangle. It can be defined as the point where the internal angle bisectors of the triangle cross.
According to the angle bisector theorem,
⇒ [tex]\angle ZRC = \angle ARZ[/tex]
⇒ [tex]\angle ARZ = 35\degree[/tex]
Let the unknown angle, ∠ZTB be x. Then ∠BTC = 2x
The sum of the interior angles of a triangle is equal to 180°,
So, [tex]24+24+35+35+2x=180[/tex]
⇒ [tex]118+2x=180[/tex]
⇒ [tex]2x=180-118[/tex]
⇒ [tex]x=\frac{62}{2}[/tex]
⇒ [tex]x=31[/tex]
Hence we can conclude that the measure of angle ∠ZTB of triangle SRT is 31°.

Answer:
A) Slope =
[tex]m = \frac{1}{4} x[/tex]
explanation:
Take 2 random points off the line, I used (4,1) & (8,2)
The formula to find the slope when given 2 points is
[tex]m = \frac{rise}{run} = \frac{y2 - y1}{x2 - x1} [/tex]
so in this case x1 & y1 are assigned to (4,1)
4 = x11 = y1and x2 & y2 are assigned to (8,2)
8 = x22 = y2so substitute the numbers into the formula and solve !
[tex] m= \frac{y2 - y1}{x2 - x1} = \frac{2 - 1}{8 - 4} = \frac{1}{4} [/tex]
this will result in the answer I got above!!
B) yes it does show a constant rate of change cause it's increasing in 1/4x intervals
C) just because you move the placement of a line on the graph doesn't mean it's going to effect the slope as long as the numbers on the axis don't change!!

A baby blue whale can gain up to 200 pounds a day after it is born. If a baby blue whale has gained 7 x 103 pounds since its birth, how many days old is it?Express your answer
in standard notation.
Answers
Answer:
35 days
Step-by-step explanation:
Weight gain per day = 200 pounds
Weight gained by a whale since birth = [tex] 7*10^3 [/tex] pounds
Number of days of the whale = [tex] \frac{7*10^3}{200} = \frac{7*10*10*10}{200} [/tex]
[tex] = \frac{7*1000}{200} = \frac{7000}{200} = \frac{70}{2} = 35 [/tex]
In standard notation form, the whale is 35 days old.

True standard deviation (σ) = 4
α = 0.01
Mean (m) of the data:
Σ(X) /n = 520.7/20
m = 26.035 = 26.04
Uaing calculator :
Sample standard deviation (s) = 4.785
Null hypothesis : μ = 25
Alternative hypothesis : μ > 25
Test statistic (t) : (m - μ) / (s/√n)
t = (26.04 - 25) / (4.785/√20)
t = 0.972
We can obtain the p value using the pvalue from t score calculator :
df = n - 1 = 20 - 1 = 19

Sanderson Manufacturing produces ornate, decorative wood frame doors and windows. Each item produced goes through three manufacturing processes: cutting, sanding, and finishing. Each door produced requires 1 hour in cutting, 30 minutes in sanding, and 30 minutes in finishing. Each window requires 30 minutes in cutting, 45 minutes in sanding, and 1 hour in finishing. In the coming week Sanderson has 40 hours of cutting capacity available, 40 hours of sanding capacity, and 60 hours of finishing capacity. Assume all doors produced can be sold for a profit of $500 and all windows can be sold for a profit of $400.
Required:
a. Formulate an LP model for this problem.
b. Sketch the feasible region.
c. What is the optimal solution?
Answers
Answer:
Let X1 be the number of decorative wood frame doors and X2 be the number of windows.
The profit earned from selling each door is $500 and the profit earned from selling of each window is $400.
The Sanderson Manufacturer wants to maximize their profit. So for this model, the objective function is
Max: 500X1 + 400X2
Now the total time available for cutting of door and window are 2400 minutes.
so the time taken in cutting should be less than or equal to 2400.
60X1 + 30X2 ≤ 2400
The total available time for sanding of door and window are 2400 minutes. Therefore, the time taken in sanding will be less than or equal to 2400. 30X1 + 45X2 ≤ 2400
The total time available for finishing of door and window is 3600 hours. Therefore, the time taken in finishing will be less than or equal to 3600. 30X1 + 60X2 ≤ 3600
As the number of decorative wood frame door and the number of windows cannot be negative.
Therefore, X1, X2 ≥ 0
so the question s
a)
The LP mode for this model is;
Max: 500X1 + 400X2
Subject to:
60X1 + 30X2 ≤ 2400
]30X1 +45X2 ≤ 2400
30X1 + 60X2 ≤ 3600
X1, X2 ≥ 0
b) Plot the graph of the LP
Max: 500X1+ 400X2
Subject to:
60X1 + 30X2 ≤ 2400
30X1 + 45X2 ≤ 2400
30X1 + 60X2 ≤ 3600
X1,X2
≥ 0
In the uploaded image of the graph, the shaded region in the graph is the feasible region.
c) Consider the following corner point's (0,0), (0, 53.33), (20, 40) and (40, 0) of the feasible region from the graph
At point (0, 0), the objective function,
500X1 + 400X2 = 500 × 0 + 400 × 0
= 0
At point (0, 53.33), the value of objective function,
500X1 + 400X2 = 500 × 0 + 400 × 53.33 = 21332
At point (40, 0), the value of objective function,
500X1 + 400X2 = 500 × 40 + 400 × 0 = 20000
At point (20, 40), the value of objective function
500X1 + 400X2 = 500 × 20 + 400 × 40 = 26000
The maximum value of the objective function is
26000 at corner point ( 20, 40 )
Hence, the optimal solution of this problem is
X1 = 20, X2 = 40 and the objective is 26000

The slope of the line that passes through the points in the table is -2/7.
What is Slope?Slope of a line is the ratio of the change in y coordinates to the change in the x coordinates of two points given.
Given a table which shows the points on the line.
Slope of a line passing through two points (x, y) and (x', y') is,
Slope = (y' - y) / (x' - x)
Take any two points on the line.

There are a fixed number of trials (n). Each trial are independent of the others. Each trial has only two outcomes: Success and Failure Each trial has the same probability of success (p).If a random variable X is used in an experiment and the experiment has all the above mentioned properties, then the random variable X is known as a binomial random variable.
(A)
Selecting five cards, one at a time without replacement, from a standard deck of cards. The random variable is the number of face cards obtained.
X = number of face cards .
There are n = 52 cards in a standard deck of cards.
There are 12 face cards in the standard deck of cards.
The probability of selecting a face card is, [tex]p=\frac{12}{52}=0.231[/tex].
The selection is done without replacement.
Thus, the experiment is a binomial experiment.
(C)
Survey 150 college students to see whether they are enrolled as new students. The random variable represents the number of students enrolled as a new student.
X = number of students enrolled as a new student.
The number of students selected for the survey, n = 150.
Each students response is independent of the others.
Thus, the experiment is a binomial experiment.

Shannon was born on 12/21/1982. How many eight-digit codes could she make using the digits in her birthday?
Answers
Answer:
The value is [tex]Z = 1120 \ eight -digit \ code [/tex]
Step-by-step explanation:
From the question we are told that
The birth date of Shannon is 12/21/1982
Generally the number of digits present in her birth date is N = 8
Looking at the date we can see that 1 repeated 3 times
2 repeated 3 times
Generally the total number eight -digit code that she could make using her birthday given the total number of digits that make up her birth date is N = 8
is mathematically represented as
K = 8!
but but given that digit 1 repeated itself 3 times , and 2 repeated itself 3 times then the total number of eight -digit code that she could make using her birthday will be mathematically evaluated as
[tex]Z = \frac{K}{3 ! * 3!}[/tex]
=> [tex]Z = \frac{8!}{3 ! * 3!}[/tex]
=> [tex]Z = \frac{8* 7*6*5* 4 * 3!}{3 ! * 3* 2*1 }[/tex]
=> [tex]Z = 1120 \ eight -digit \ code [/tex]
Shannon could make 40,320 eight-digit codes using her digits in her birthday.
Given that Shannon was born on 12/21/1982, to determine how many eight-digit codes could she make using the digits in her birthday, the following calculation must be performed:
8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 = X 56 x 30 x 12 x 2 = X 1680 x 24 = X 40320 = X
Therefore, Shannon could make 40,320 eight-digit codes using her digits in her birthday.
