Answer:
your answer is D
Step-by-step explanation:
Answer: 2.5%
Step-by-step explanation:
Mean score = 65
Standard deviation = 5
Score (x) = >75
Z-score = [(score - mean) ÷ standard deviation]
Z - score = [(75 - 65) ÷ 5]
Z - score = 10 ÷ 5 = 2
P(score higher than 75) = 100 - 95 = 5/2 = 2.5%
2 times 2 times 2 equals 8.
8 plus 1 equals 9
9 plus 4 equals 13.
The answer is 13.
