If polygon PQRS with P(2, 4), Q(4, -6), R(0, -2), and S(-2, 2) is dilated by a scale factor of 5/2, then the new coordinates are
O P (2, 4), Q'(4.-6), R'(0, -2), and S'(-2, 2)
O P'(1,2), Q(2,-3), R'(0, -1), and S'(-1,1)
P'(5, 10), Q'(10.-15), R'(0,-5), and S'(-5,5)
O P(10, 20), Q'(20, -30), R'(0, -10), and S(-10,10)

false

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
