Answer: 0.4758
Step-by-step explanation:
Given : Mean : 
Standard deviation : 
Also, the new population of pilots has normally distributed .
The formula to calculate the z-score :-
For x=130 lb .
For x=171lb.
The p-value =
Hence, the required probability : 0.4758
4 and -2.5
You can get this by first factoring the equation.
(2x + 5)(x - 4)
Then set both equal to zero and solve individually.
1. A
2. B
3. B
4. D=11
5. 25, 20,
By order of operations, the answer above which is marked brainliest is incorrect

I always guyed myself as a happy face. If it is happy it is linear. :)
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.
