The scale of a is 1 in : 25 yd. find the length on the drawing
if the actual length is 512.5 yd. u will be marked and get 90 points

20.5 inches

Step-by-step explanation:

1 inch= 25 yd

the total length is 512.5

divide 512.5 yd by 25 yd

that will be 20.5 inches

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
