Answer:
78.81%
Step-by-step explanation:
We are given;
Population mean; μ = 149
Sample mean; x¯ = 147.8
Sample size; n = 88
standard deviation; σ = 14
Z-score is;
z = (x¯ - μ)/(σ/√n)
Plugging in the relevant values;
z = (147.8 - 149)/(14/√88)
z = -0.804
From z-distribution table attached, we have; p = 0.21186
P(X > 147.8) = 1 - 0.21186 = 0.78814
In percentage gives; p = 78.81%
Answer:
-14
Step-by-step explanation:
just like 8+6 = 14
-8-6 = -14
Answer:
1.6
Step-by-step explanation:
3x-3=27
-3=-3
3x=24
3x/3=24/3
X=8
The answer is -34 k^8 z^12.
