Part A: Scatter plot with best-fit line attached. You'll find the line to have equation (approximately)

The positive slope suggests that test scores and study time are directly are proportional.
Part B: Same as in a previous question you had posted. Pick two points on the provided line and compute the slope as best you can. For example, I might pick (2, 30) and (4, 40), which gives a slope of

and assuming the line passes through (2, 30) exactly, it would have equation

I pretty sure you times it by 3 and then you get 21:18
Answer:
9 inches of snow fell in the 7-hour snowstorm.
Step-by-step explanation:
To find your answer write an equation to find your answer.
1 inch per hour for two hours 1(2)
2 inches per hour for four hours 4(2)
and 1 inch in the last hour
so add those up
1(2)+4(2)+1
2+8+1
9
Answer:
5/12
Step-by-step explanation:
1. Convert 1/4 to 3/12, then convert 1/3 to 4/12
2. Then add 3/12 and 4/12 together, which would be 7/12
3. Then subtract 12/12 by 7/12 which would be 5/12
So, 5/12 is your answer.
Hope this helps
The mean of the ages of the men that are given will be 22.1.
<h3>How to calculate the mean?</h3>
It should be noted that mean simply means average. The mean of the men will be:
= (27 + 20 + 20 + 19 + 19 + 25 + 24 + 21 + 22 + 24) / 10
= 221/10
= 22.1
Therefore, the mean of the ages of the men that are given will be 22.1.
