By definition of conditional probability,
P(B | A) = P(A ∩ B)/P(A) = (13/25) / (13/20) = 20/25 = 4/5
L = W + 55
2L + 2W = 4242
L + W = 2121
(W + 55) + W = 2121
2W + 55 = 2121
W = 1033 inches L = 1088 inches
Answer: y=0,5x²-x-1,5.
Step-by-step explanation:

We summarize (1) and (3):

Substitute b=-1 into (2):

From (5) subtract (4):

Substitute a=0,5 into (4):

Hense:
