Answer:
(a) E(X) = 3
(b) Var(X) = 12.1067
Explanation:
(a) E[X]
E[X]T = E[X]T=A + E[X]T=B + E[X]T=C
= (2.6 + 3 + 3.4)/3
= 2.6 (1/3) + 3(1/3) + 3.4(1/3)
= 2.6/3 + 1 + 3.4/3
= 3
(b) Var (X) = E[X²]−(E[X])²
Recall that if Y ∼ Pois(λ), then E[Y 2] = λ+λ2. This implies that
E[X²] = [(2.6 + 2.6²) + (3 + 3²) + (3.4 + 3.4²)]/3
= (9.36 + 12 + 14.96)/3
= 36.32/3
= 12.1067
Var(X) = E[X²]−(E[X])²
= 12 - 3²
= 12.1067 - 9
= 3.1067

Answer:
n= 6.11 years
Explanation:
Giving the following information:
Present value= $40,000
Future value= $20,000
Decrease rate= 0.12
<u>To calculate the number of years for the car to reach a value of $20,000; we need to use the following formula:</u>
n= ln(FV/PV) / ln(1+i)
n= ln(20,000/40,000) / ln(1.12)
n= 6.11 years
