The scale of a dollhouse is 1:12 . If it is modeled after an actual house that is 40 feet tall, how tall is the dollhouse? A: 4 1/2 feet tall
B: 4 feet tall
C: 2 3/4 feet tall
D: 3 1/3 feet tall

the dollhouse is 3 1/3 feet tall

Step-by-step explanation:

40/12 is 3 1/3

Sorry if i get it wrong hope it helps

what i would say the best answer is a. 40.5

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
