Answer:
d ) f(x)= -5x-19 is most likely
Answer:
330(D)
Step-by-step explanation:
So lets go over what we know:
#1: 44 out of 80 people think they have a average fitness level.
#2: 80 out of the 600 people in the school were surveyed.
Using what we know, lets try and find the answer.
So lets divide the total amount of people, by the amount of people that took the survey:
600/80
=
7.5
Ok, so now we know that we need to take 7.5 surveys to find out what all the students think of their fitness level.
Now lets take teh amount of people in a single survey, with average fitness(44), and multpliy it by how many surveys are needed for the whole school(7.5):
44*7.5
=
330
This is the amount of people in the whole school who think they have an average fitness level.
I hope this helps! :)

Answer:
y= −1 + x/3
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
A manager wants to test whether two normally distributed and independent populations have equal variances. the appropriate test statistic for this test is a "F-statistics."
<h3>
What is F-statistics?</h3>
An F statistic is a value obtained after performing an ANOVA test or even a regression analysis to determine whether the means of two populations differ significantly.
Some key features regarding the F-statistics are-
- It is comparable to a T statistic from the a T-Test; a T-test would then inform you when a single result is statistically significant, whereas a F test would then tell you if a set of variables is statistically significant.
- When determining whether your total results are significant, you must use the F statistic in conjunction with the p value. Why?
- A significant result does not imply that all of your variables have been significant.
- The statistic is simply comparing the cumulative influence of all the variables.
