Troy and Ronnie wrote down how much time they spent at play rehearsal each week for 6 weeks. Troy spent 6, 4, 8, 5, 10, and 9 hours at play rehearsal. Ronnie spent 4, 6, 3, 7, 7, and 3 hours at play rehearsal. How does the range of hours Troy spent compare with the range of hours Ronnie spent at play rehearsal? Answer the questions to find out. 1. What is the range of hours Troy spent at play rehearsal? Explain how to find the range of a data set. Write your answer in the space below. 2. What is the range of hours Ronnie spent at play rehearsal? Write your answer in the space below. 3. Who had a greater range of hours spent at rehearsal? Write your answer in the space below.

answer: the answer is b. i think hope i got it correct

step-by-step explanation:

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 answer is  

a.

28 ft2

step-by-step explanation:

192/15 = 12.8.

12.8

step-by-step explanation:

192/15 is 12.8.

however, it says to round to the nearest foot, which would equal 13.
