Answer:
The answer is 5:12
Step-by-step explanation:
It is 5:12 because We already know that 7 pens are blue. To find the number of red pens we must subtract 12 - 7 and get 5 as the number of red pens. Now knowing the no. of red pens and total number we can say the ratio of red pens to total no. is 5:12

Answer:
D
Step-by-step explanation:
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
