A scale factor of 2 is used to dilate figure WXYZ with the origin as the center of dilation to create W'X'Y'Z'. Which rule below describes this dilation? A) (X, Y)-(1/2xy)

B) (X, Y)-(2xy)

C) (X, Y)-(1/2x,1/2y)

D) (X, Y)-(2x,2y)

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

your answer is

a.
