Decide whether each table could represent a proportional relationship. If the relationship could be proportional, what would be the constant of proportionality?
a. The sizes you can print a photo:
b. The distance from which a lighthouse is visible:
width of photo (inches) height of photo (inches) height of a lighthouse
distance it can be seen
(miles)
(feet)

the answer to this question is yes

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
