Part A Mike has $72 and he needs to buy some apples. Which of these equations would represent Mike's situation if the apples cost $0.60 per apple and he wanted to find out how many apples (x) he could buy?

A 72(0.60)=x

B. 72 - x = 0.60

C. 72 - 0.60 = x

D. 72 = 0.60x

Part B
Find the number of apples (x) he could buy.

80%

step-by-step explanation:

85.560%

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560

central angle of a triangle has the same measure as its intercepted arc.
