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 correct answer is (C) $401,302
Explanation:
To get how much the contest winner actually won, we have to calculate the amount receive at the end of each year discounted at this moment. Then, we added all the payments.
For example, the first payment in $200,000 at this moment, so we add $200,000.
At the end of the first year we receive $30,000, and the rate of discount is 8%
The formula of discount is P=A/ (1+r)ⁿ
A=Final amount
P= Principal
r= interest rate
n= time
Year 1 = A/ (1+r)ⁿ
=$30,000/1,08¹= 27777,77
Year 2 =$30,000/1,08²= 25720,16
Year 3=23814,96
Year 4=22050,89
Year 5=20417,49
Year 6=18905,08
Year 7=17504,71
Year 8=16208,06
Year 9=15007,46
Year 10=13895,80
Total 401302,44

<em><u>If I had any advice for DreamWorks Classics, it would be to insist on adopting the 'organic' approach for internationalising Postman Pat.</u></em>
Explanation to the following is as follows;
Postman Pat chronicles the exploits of Pat Clifton, a postal worker for the Royal Mail in the imaginary community of Greendale. This product image is firmly ingrained in British habits and culture; therefore, it is unlikely that Postman Pat would have succeeded if they had followed the ‘born global' path when launching this cartoon.
