Acandy store sells mints in 1/4, 1/2 , and 3/4 lb packages. john purchases several packages of each weight. what is the total weight of each purchase? enter a whole number or a mixed number in simplest form to correctly complete the sentence. 6 packages of the 1/4 lb package weigh lb. 8 packages of the 1/2 lb package weigh lb. 7 packages of the 3/4 lb package weigh lb.

For this problem, just multiply the fractions by the amount of packages purchased.

6 * 1/4 = 1 1/2

8 * 1/2 = 4

7 * 3/4 = 5 1/4

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

a_n = a_1 + (n - 1)d

the first term is 6.

the common difference d = ?

when you find d, replace n with 7 and d with the common difference to find your answer.
