Susan found a bag of 20 golf balls at a garage sale, and bought the bag for $2.00. Express the ratio of cost to number of balls in lowest terms. Use the colon to write the ratio.

10 cents : 1 ball

Step-by-step explanation:

$2.00 : 20 balls = $1.00 : 10 balls = 100 cents : 10 balls = 10 cents : 1 ball

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

answer: idk wbu

step-by-step explanation: umm..
