A teacher gave a unit test to both of her statistics classes. The mean test grade for Class A was 77 points, with a standard deviation of 5 points, whereas the mean test grade for Class B was 80, with a standard deviation of 7 points. Kyle, in Class A, received an 82 on the test, and Caleb, in Class B, received an 87. Whose performance on the unit test was better relative to their class?

Answers

Answer:

i think they would be the same

Step-by-step explanation:

77+5=82 or 77-5=72

so he is within the range of 72-82

80+7=87 80-7=73

so he is also within the range of 73-87

Since both Kyle and Caleb scored 1 standard deviation above their respective class means, we can conclude that their performances were relatively equal.

What is standard deviation?

A standard deviation is a measure of how far apart the data is from the mean.

A low standard deviation indicates that data is clustered around the mean, whereas a high standard deviation indicates that data is more spread out.

To determine whose performance was better relative to their class, we need to calculate their z-scores, which tell us how many standard deviations a particular score is from the mean.

For Kyle in Class A:

z-score = (82 - 77) / 5 = 1

This means that Kyle's score is 1 standard deviation above the mean for his class.

For Caleb in Class B:

z-score = (87 - 80) / 7 = 1

This means that Caleb's score is also 1 standard deviation above the mean for his class.

Thus, we can conclude that Kyle and Caleb's performances were comparable because they both scored one standard deviation above their respective class means.

The total operating cost to run the organic strawberry farm varies directly with its number of acres. What is the constant of variation in this scenario?

Answers

Answer: 16 acres

Step-by-step explanation: we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

Let

x ----> the number of acres

y ---> total operating costs

we have the ordered pair (20,551,520)

For x=20 acres, y=$551,520

Find the value of the constant of proportionality k

substitute the values of x and y

The linear equation is equal to

Find out how many acres are on a farm with a total operating cost of $441,216

For y=$441,216

substitute in the linear equation the value of y and solve for x

Step-by-step explanation:

You replace the x with 10, and the y with 60 and answer normally

13(30) = 130

5(6) = 30

130 - 30 = 100

Answers

30. since there is 1 remaining, you take that away from 59, leaving you with 58. you would then divide 58 by 2 since each classmate gets 2. that results in the final answer of 29. however, she’s in that class too so you would add one for her making it 30

Function is defined as the expression or relation between any given two variables such as x and y and there must be an independent variable and dependent variable.

In other words the function represents the graph between x and y that is for each value of x there exist one value of y but here there is no restriction in values of y that is y can have infinity values.

Given equation is nt+6-xt=s

Now solving for t by separately variables and constant :

nt+6-xt=s

t(n-x) = s-6

t = (s-6)/(n-x)

Therefor the value of t after arrangement is t = (s-6)/(n-x)

Answers

Answer: A and D

Step-by-step explanation:

I took the test online and the answer is A and D the y intercept is the cost of her lunch and the slope is the cost of one book

The true statements are the slope is the cost of one book and the y-intercept is the cost if Hana's lunch.

What is Slope?

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the

change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

Given:

as, from the graph the slope tells us about the cost of one book.

Now, From the graph if we talk about y- axis then we can see that the y- axis tells us about cost if Hana's lunch.

Hence, the true statements are the slope is the cost of one book and the y-intercept is the cost if Hana's lunch.
