Mr. Li is a math teacher at Pinkston High School who is preparing his students to take the SAT test. He collected data from 10 students who took the test last year and presented this information to the students in a table. Which linear regression equation best represents the line of best fit for the data if represents the number of hours spent studying? A y= 344.19x+22.54
B y= 344.19x−22.54
C y= 22.54x+344.19
D y= −22.54x+344.19

step-by-step explanation:

part a. the differences are decreasing, so we know the sequence is not arithmetic. the ratios are constant (=3/4), so we know the sequence is geometric.

part b. from part a, we know the common ratio is 3/4, so each term is 3/4 of the one before. the initial term is the number of gallons at h=1.

g[h] = (3/4)·g[h-1]

g[1] = 384 . . . . initial value required for a recursive definition

part c. the general formula for a geometric sequence is

a[n] = a[1]·r^(n-1)

we have a[1] = 384, r = 3/4, and the term number given by h. the formula that follows is

g[h] = 384·(3/4)^(h-1)

part d. filling in the value and doing the arithmetic, we have

g[12] = 384·(3/4)^11 ≈ 384·0.042235136 ≈ 16.2183 . . gallons

part e. each gallon is 4 quarts, so

16.2183 gal × 4 qt/gal = 64.8732 qt

15.36 per mile

but forgot to round

i am pretty sure
