So " the line of best fit " would be 5(h) to 200(m) .
Which would also be 5:200 .
So after you can divide, so 5/5 would be 1 and 200/5 would be 40.
So it would be 1 to 40 (1:40).
The equation would be 40x.
If I helped please mark as brainliest . Thanks .

A statistics professor gives a survey to each of the 20 students in an introductory statistics course. The survey asks the stude

tekilochka [14]

Answer:

$B2 = 0.465$ --- Population standard deviation

$C2 = 0.216$ --- Population Variance

Step-by-step explanation:

Given: Wake-up time data

Required: Determine the population standard deviation and the population variance using Excel

First, enter the given data in Excel

For this question, I entered the data in cell A2 through cell A21

Cell B2 and Cell C2 were used to hold the results of the population standard deviation and the population variance, respectively.

In cell B2, the formula to use is:

=ROUNDUP(STDEV.P(A2:A21),3)

The round function rounds the result to 3 decimal places while STDEV.P calculates the population standard deviation.

So, the result is:

$B2 = 0.465$

In cell C2, the formula to use is:

=ROUND(VAR.P(A2:A21),3)

The round function rounds the result to 3 decimal places while VAR.P calculates the population variance.

So, the result is:

$C2 = 0.216$

Explain why congruent figures have the same surface area?

Hatshy [7]

Congruent means exactly the same, so congruent figures have the same surface areas because they have the exact same size in each side.
