Edge 2021
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%
Answer:
25+4+120(2min) = 149
25/149 = 0.16778523489932885906040268456376
= (rounded) 0.17
Answer:
d 16 x^4 y^12
Step-by-step explanation:
(2xy^3)^4
We know that
(ab)^c is a^c b^c
So
2^4 x^4 y^3^4
We also know that a^b^c is a^(b*c)
16 x^4 y^(3*4)
16 x^4 y^12
