Answer:
a. 0.5
Step-by-step explanation:
We know that X follows normal distribution with
mean=75
standard deviation=8
P(0<Z<∞)
The area under the normal curve is 1 and the (0<Z<∞) =0.5 and (-∞<Z<0) =0.5
So, P(0<Z<∞)=0.5
Hence the P(X ≥ 75)=0.5
Answer:
Step-by-step explanation:
Let u be a differentiable function , then
(1)
Given function :
Differentiate both sides with respect to x , we get
(By using (1))
[∵
]
Hence, the derivative of the given function is .
