D because it is involving the proper way to use commas
Explanation:
The value of each score from the z-score can be calculated using x = 45 + 8.3z
<h3>How to determine the distance from the mean?</h3>
The given parameters are:
- Mean = 45
- Standard deviation = 8.3
The z-score is calculated using:

This gives

Multiply both sides by 8.3
x - 45 = 8.3z
Add 45 to both sides
x = 45 + 8.3z
Hence, the value of each score from the z-score can be calculated using x = 45 + 8.3z
