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%

Step-by-step explanation:
i hope this helped!
p.s it would be cool if you gave me brainliest.
3 x + 3 (x + y)
3 (2 x + y)
6 x + 3 y
y = -2 x
y = -2 x (3 (x + y) + 3 x) = 6
(3 (x + y) + 3 x) = 3
(3 x + 3 (x + y)) dx = 3 (x^2 + x y) +
(x^2 + y^2<R^2)(3 (x + y) + 3 x) dx dy = 0
(3 x + 3 (x + y)) dy dx = 0
Step-by-step explanation:
Hope this helps ツ
