Step-by-step explanation:
why the hell do our teachers do this to us ;(
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?
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?
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
so
For y=$441,216
substitute in the linear equation the value of y and solve for x

solve nt+6-xt=s for t
Answer:
[tex]t=\frac{s-6}{n-x}[/tex]
Step-by-step explanation:
[tex]nt+6-xt=s[/tex]
[tex]\mathrm{Subtract\:}6\mathrm{\:from\:both\:sides}[/tex]
[tex]nt+6-xt-6=s-6[/tex]
[tex]Simplify[/tex]
[tex]nt-xt=s-6[/tex]
[tex]nt-xt[/tex]
[tex]=t\left(n-x\right)[/tex]
[tex]t\left(n-x\right)=s-6[/tex]
[tex]\frac{t\left(n-x\right)}{n-x}=\frac{s}{n-x}-\frac{6}{n-x};\quad \:x\ne \:n[/tex]
[tex]t=\frac{s-6}{n-x}[/tex]
Therefor the value of t after arrangement is t = (s-6)/(n-x)
What is Mathematical function ?
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)
