Answer:
(4,0)
Step-by-step explanation:
Graph the equations and locate the intersection.
P(A|B)= P(B and A) / P(A)
P(B and A) = .3 + .10 = .13 P(A)= .3
So,
P(A|B)= .13/.3
P(A|B)= 0.43333...
Answer:
3x - 11
Step-by-step explanation:
(x-4)+(2x-7)

x - 4 + 2x - 7 Combine like terms
x + 2x - 4 - 7
3x - 4 + - 7
3x - 11
