1. find the correlation coefficient of the line of best fit for the points (−3, –, –40), (1, 12)(1, 12), (5, 72)(5, 72), and (7, 137)(7, 137). explain how you got your answer. use the coefficient to describe the correlation of this data

y = 16.9237x + 2.94075 ( solution is attached below)

hows it hangin lol

step-by-step explanation:

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
