Barack Obama is the President of the US
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 and Explanation:
Artists' lives have been changed by digital technology. This has created different schools of thought such as the "winner take all" theory, which claims that delivering high quality products at low cost will create a world where small differences in talent demand large differences in reward, and the "long tail" theory, who claims that digital technology is creating a small portion of sellers that the market will adapt to, promoting low-cost products. These two theories are effective in different realities. However, the existence of both proves the change that programming and technology has been showing in entertainment and in the market.
Answer:
A. 56.32 days
B. 40.38 days
Explanation:
The Operating cycle is the Inventory period + AR period
Inventory period= 365/(Cost of goods sold/Average inventory)
Average inventory= (Beginning Inventory + Ending Inventory)/2
Accounts Receivable period= 365/(Credit Sales/Average Accounts Receivable )
Average Accounts Receivable= (Beginning Accounts Receivable + Ending Inventory Accounts Receivable)/2
Calculated Inventory period= 42.58 days
Calculated Accounts Receivable period= 13.74 days
The Cash cycle is also called the Net Operating cycle which is the Inventory period + Accounts Receivable period- Accounts Payable period
Accounts Payable period= 365/(Cost of goods sold/Average Accounts Payable)
Average Accounts Payable = (Beginning Accounts Payables + Ending Inventory Accounts Payable)/2
Calculated Accounts Payable period= 15.94 days
