Which of the following experiments could be used to simulate an event in which the probability of success, p(success), is 0.60, and the number of successes out of 20 events is desired? a. use a spinner that is divided into 5 equal parts. choose 3 colors for a success; the other 2 colors will represent unsuccessful. spin the spinner 20 times, once for each event. b. use a random number table consisting of the digits 0–9, with digits 0 through 3 representing a success and the remaining digits 4 through 9 representing unsuccessful. choose 20 digits, one for each event.

1 1/7 hope i

step-by-step explanation:

8/7 = (1 * 7 + 1) / 7 = 1 + 1/7 = 1 1/7

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
