Answer:
519
Step-by-step explanation:
Let's assume that the scores for the national verbal proficiency test follow a normal distribution.
Mean score (μ) = 500
Standard deviation (σ) = 75
According to a Z-score table, the score for the 60th percentile is roughly z = 0.253
For any score "x", the z-score is given by:

For z = 2.53:

The raw score to the 60th percentile is 519.
Find the Greatest Common Factor (GCF)
GCF = 2
Factor out the GCF (Write the GCF first. Then, in parentheses, divide each term by the GCF.)
2(16x/2 + 42y/2)
Simplify each term in parenthesis
<u>C. 2(8x + 21y) </u>
