Lincoln and his children went into a bakery and where they sell cookies for $1 each

and brownies for $1.75 each. Lincoln has $15 to spend and must buy at least 9 cookies

and brownies altogether. If Lincoln decided to buy 7 cookies, determine the

maximum number of brownies that he could buy. If there are no possible solutions,

submit an empty answer.

answer: the answer is 127 degrees

they are simplified

step-by-step explanation:

definitely a. the others have almost all data points on one side of the line.

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
