Answer:
Lorenzo's score on exam was 75.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 61
Standard Deviation, σ = 8
We are given that the distribution of test score is a bell shaped distribution that is a normal distribution.
Formula:

z-score = 1.75
We have to find the value of x.
Putting values, we get

Thus, Lorenzo's score on exam was 75.
1) 4x + 12x² + 9 + 3y + 2x + 11y
6x + 12x² + 14y + 9
2) x² + 2y + 15x² + 4x + 21
4x + 16x² + 2y + 21
3) 8x + 12 + 17y + 3x + y + 8
11x + 18y + 20
Hope this helps :)
