Answer:
Mean = 16.5
Variance = 35.55
Step-by-step explanation:
<u> x P(x) x. P(x) x² x². P(x)</u>
6 0.10 0.6 36 3.6
12 0.35 4.2 144 50.4
18 0.25 4.5 324 81
<u> 24 0.30 7.2 576 172.8</u>
∑x P (x) 16.5 ∑x² P (x) 307.8
The expected value of x E[X] gives the mean where X is the discrete random variable with the given probabilities.
Mean is given by E(X)= ∑x P (x) = 16.5
Similarly the variance is also calculated using the expected value of X and X².
Variance is given= E(X)²- [E(X)]²= 307.8- (16.5)²= 307.8-272.25 = 35.55

Answer:
a) 7.78 months
b) 1116
Step-by-step explanation:
Given -
Integrating the above equation with respect to time, we get -
let us define new variable x
substituting these values in above integral equation, we get -
at t = 0, P (0) = 1075, using this condition, we get -
