please answer today if possible !!! At a bookstore, Lane selected 3 paperbacks that were all the same price and 2 hardcover books that were each the same price. When he got to the register, he found out that all books were on sale for 15% off. Lane decided to use a $20 gift card to pay for part of his purchase and pay the balance in cash. If p is the regular price of each paperback and h is the regular price of each hardcover that Lane buys, which expression shows the amount (in dollars) that Lane still owed?

16

step-by-step explanation:

2 x 40 = 80

80/5

= 16

relating to or denoting a system of numbers and arithmetic based on the number ten, tenth parts, and powers of ten.

step-by-step explanation:

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
