Since, the only thing I can do with this is factor, here you go 6 ( 2 a + b ).
Answer:
option C
Step-by-step explanation:
C
First we find the z-score.
z = (x - μ) / σ
z = (520 - 500) / 60
z = 0.33
Using a calculator or z-score table:
P(z < 0.33) = 0.6293
The probability is approximately 63%. Answer C
(3 + 2) - 3² = 5 - 9 = -4
