Which event has a 50% chance of occurring? A rolling a 2 with a fair number cube numbered 1 to 6. B rolling a number less than 5 on fair number cube numbered 1 to 6. C a fair spinner that has equal parts blue, yellow, and red, stopping on blue. D a fair spinner with equal parts red and blue, stopping on red

if the pizza is divided equally into 2 equal halves then you would get

πr^2/2

where r is the radius of the pizza.

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

y=sec x is the correct answer
