It cost $480 to rent apartment on the gold coat for a weekend.
last year. it cost $400.00.
what method do i use to calculate the % off increase?

answer:

you would find the difference of the prices and divide the value by the original price, the difference would be 80, 80/400 is 1/5 which is 20%. you could write a set of equations or use the interest formula, where p equals the principal amount. r equals the rate/ percentage of interest, n equals the compounding periods and t equals time. hope this ! : )

x = 12

y = 15

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
