Rewrite as:
Answer:
Step-by-step explanation:
P = J - 15
P + J = 55
(J - 15) + J = 55
2J = 40
J = 20 years
Answer:
Step-by-step explanation:
Given
--- Mean
--- Variance
Calculate the standard deviation
Solving (a): P(X < 1.96)
First, we calculate the z score using:
This gives:
The probability is then solved using:
From the standard normal distribution table
So:
Solving (b): P(X > 1.64)
First, we calculate the z score using:
This gives:
The probability is then solved using:
From the standard normal distribution table
So:
Solving (c): P(0.5 < X < 0.5)
This can be split as:
In probability:
becomes
