Answer:
- Elanor's standardized score is 1.19
- Gerald's standardized score is 0.72
- Elanor has higher score
Step-by-step explanation:
To compare Elanor's and Gerald's math scores, we need to standardize them and calculate their z-scores.
z score can be calculated using the formula
z= where
- M is the mean score of the exam
- s is the standard deviation of the exam
Elanor's standardized score is:
z(e) = ≈ 1.19
Gerald's standardized score is:
z(g)= ≈ 0.72
Since z(e) > z(g), Elanor has higher score

Answer: A) 30</h3>
===========================================
Work Shown:
SM/MK = RM/ML
33/44 = x/40
3/4 = x/40
3*40 = 4*x ... cross multiply
120 = 4x
4x = 120
x = 120/4
x = 30
RM = 30
