If the distance from the center of dilation to one line is 9, and the distance from the center of dilation to a parallel line is 2.5, what scale factor should be used to map the first line onto the second? A. The scale factor is the distance of the mapped image times the distance of the original image, 2.5×9=22.5

B. The scale factor is the distance of the original image over the distance of the mapped image, 92.5=3.6

C. The scale factor is the distance of the mapped image over the distance of the original image, 2.59≈0.28

D. The scale factor is equal to half of the distance to the original image, 92=4.5

step-by-step explanation:

if you have eyes and you can use them efficiently you can see that it just looks like random dots like do a line of best fit and like they're so spread out it's such a weak association you might as well consider it nonexistent

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
