Do the values in the table represent a proportional relationship? select from the drop-down menu to correctly complete the statement. all of the y-values: a. are b. are not a constant multiple of the corresponding x-values, so the relationship a. is not proportional b. is proportional

NOT proportional

Step-by-step explanation:

y/x  = 5/2 = 2.5

y/x = 6/3 = 2

also 7/4 = 1. 75 and 8/5 = 1.6  so:-

They are NOT proportional

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
