consider the original trapezoid and the enlargement. what is the length of side a, in centimeters, on the enlarged trapezoid?

Step-by-step explanation:

The first step to solve this exercise is to find the Scale factor.

By definition, the Scale factor is the ratio of the length of any side of one of the figures to the lenght of the corresponding side of the other one.

Based on this, you get that, in this case, the Scale factor is:

Therefore, since you need to find the lenght of the side "A", you must multiply the lenght of the corresponding side of the other figure, by the Scale factor.

Then you get that the lenght of the side "A" is:

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

answer: 72: 111
