Factorize
(3n + 8) (3n - 8) = 0
3n + 8 = 0 and 3n - 8 = 0
Solve both for n
3n + 8 = 0
3n = -8
n = -8/3
3n - 8 = 0
3n = 8
n = 8/3
Therefore n = -8/3 and n = 8/3

Answer:
C
Step-by-step explanation:
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
