Answer:
40%
Step-by-step explanation:
Probability that student is a male Given that it's a senior ::
Recall :
P(A | B) = (AnB) / B
Hence, we have ;
P(male | Senior) = number of (Male n Senior) / total Senoirs
From the table :
Total seniors = 2 + 3 = 5
Male n Seniors = 2
P(male | Senior) = 2 / 5 = 0.4 = 40%
Answer:
8/(x + 2) - 4/(x + 6)
Step-by-step explanation:
4x + 40 = Ax + 6A + Bx + 2B
Equating coefficients of x
4 = A + B (1)
Equating constant terms:
40 = 6A + 2B (2)
Multiply equation (1) by -2:
-8 = -2A - 2B .. (3)
Add (2) and (3):
32 = 4A
A = 32/4
A = 8.
4 = 8 + B
B = 4 - 8
B = -4.
