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:
% in T bills = 18.92%, % in P = 81.08%
Explanation:
Portfolio return = Weighted average return
Return of portfolio P = 0.14*0.6 + 0.10*0.4
Return of portfolio P = 0.124
Let % money in T bills be x
0.11 = 0.05*x + 0.124*(1-x)
0.11 = 0.05x + 0.124 - 0.124x
0.014 = 0.074x
x = 18.92%
Hence, % in T bills = 18.92%, % in P = 81.08%
Answer:
The correct option is E
Explanation:
The formula to compute the accounts receivable turnover of the company for the Year 2 is as:
Accounts Receivable Turnover = Net Credit Sales / Average Accounts Receivable
where
Net Credit Sales be $723,000
And
Average Accounts Receivable is computed as:
Average Accounts Receivable = Accounts receivable Year 1 + Accounts receivable Year 2 / 2
= $86,500 + $82,750 / 2
= $169,250 / 2
= $84,625
Putting the values in the above formula:
= $723,000 / $84,625
= 8.54
Answer: Transferring debit and credit amount from the journal to the ledger.
Explanation:
Posting in Accounting refers to the process of transferring debit and credit amounts from the books of original entry i.e the journals, to the relevant general ledger.
Posting to the general ledger is the third step in the Accounting Cycle and as such is very important in determining the balances to put into the Unadjusted Trial balance.
Answer:
d. $625,000
Explanation:
cost of goods available for sale = cost of goods manufactured during the current period + finished goods inventory at the beginning of the period
- cost of goods manufactured during the current period = $600,000
- finished goods inventory at the beginning of the period = $25,000
cost of goods available for sale = $600,000 + $25,000 = $625,000
cost of goods sold = cost of goods available for sale - ending inventory = $625,000 - $40,000 = $585,000
