Determine if the method is fair. If it is not, how can it be adjusted to make it fair? A. The method is not fair. This can be resolved by finding the product of the outcomes of three spins instead of two.
B. The method is not fair. This can be resolved by using the sum of the two outcomes instead of the product.
C. The method is not fair. This can be resolved by using the same method with a spinner with only two same-sized sections instead of four.
D. The method is fair.

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

the eight graders whould be the answer
