Aphoto of a painting measures 13 inches by 17inches. the scale of the photo to the original painting is 1 inch to 3 inches . what size is the painting?

39 inches by 51 inches

Step-by-step explanation:

Since your scale is 1 inch to 3 inches, you multiple the photo measurements by 3 to get the original painting size.

898.1666667

step-by-step explanation:

5389/6 = 898.1666667

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
