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:
The account balance after 4 years will be $2,420.
Explanation:
First we need to add Bob and Judy's amount to find the total amount that will be deposited. (1260+975)=2,235.
Now we will break up the annual interest into monthly interest because it will be compounded monthly. 2/12=0.166.
Then we will break up the 4 years into months also because the interest is compounded monthly. 4*12=48
Now we use the formula for compound interest
Final amount = Principal*(1+R)^N
Principal = 2,235
R= 0.166% or 0.00166
N= 48
We put these values into our formula
2,235*(1+0.00166)^48
=2,420
Answer: 4,840
Explanation: Analysis reveals that a company had a net increase in cash of $22,310 for the current year.
Therefore,
The year-end cash balance - the beginning cash balance = $22,310
The beginning cash balance = The year-end cash balance - $22,310
The year-end cash balance is $27,150
The beginning cash balance = $27,150 - $22,310 = $4,840
