By definition of conditional probability,
P(B | A) = P(A ∩ B)/P(A) = (13/25) / (13/20) = 20/25 = 4/5
If that was the end and the question was "How many boxes did she sell?" then the answer is 6 boxes.
f(x) - g(x) = 2x-3 -(4x+8)
= 2x-3 -4x-8
= -2x-11
Step-by-step explanation:
30. is just asking where the two equations graphed intersect each other...
