Answer:
The student's z-score will not change
Explanation:
Z-scores are used to compare results of an individual or entity to the average population's scores.
Since the adjustment of additional points is added to each class member's score, the adjustment will shift the entire distribution of scores. However, there will not be a change in the relative position of the student's score in the class. As a result, the student's z-score will not change.

Answer:
20
Step-by-step explanation:
a)x^2+16^2=a^2
b)x^2+25^2=b^2
c)a^2+b^2=(16+25)^2
a+b)2x^2+25^2+16^2=41^2=a^2+b^2
2x^2=800
x=20
