The dot plot shows the length of the 12 trailers sold at a store last month. which statement about the data is true?

F. The interquartile range is 7, and the range is 17.

G. The interquartile range is 7, and the range is 11.

H. the interquartile range is 2.75, and the range is 17.

J. the interquartile range is 2.75, and the range is 11.

i did it myself and i got 4.2 (b) hope its right

step-by-step explanation:

is this part of a question or something

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

answer:

24pi or letter c
