Answer:
SD = 0.0740270 or 7.40270 percent rounded off to 7.403 percent
Explanation:
To calculate the standard deviation of the investment, we must first calculate the expected or mean return of the investment. The expected or mean return can be calculated as follows,
r = pA * rA + pB * rB + ... + pN * rN
Where,
- pA, pB, ... represents the probability of state occurrence
- rA, rB, ... represents return A, return B and so on under each state
r = 0.2 * 0.16 + 0.4 * 0.12 + 0.2 * 0.05 + 0.2 * -0.05
r = 0.08 or 8%
The formula to calculate the standard deviation of a stock/investment is as follows,
SD = √pA * (rA - r)² + pB * (rB - r)² + ... + pN * (rN - r)²
SD = √0.2 * (0.16 - 0.08)² + 0.4 * (0.12 - 0.08)² + 0.2 * (0.05 - 0.08)² + 0.2 * (-0.05 - 0.08)²
SD = 0.0740270 or 7.40270 percent rounded off to 7.403 percent
Answer:
D. Any of the above, depending on the transactions
Explanation:
The double entry principle simply means that any accounting transaction has two records: one credit, and one debit, and it depends on the nature of the transaction, and of the accounts involved which specific value is credited and which one is debited.
For example, if a firm purchases 100$ of office supplies with cash, the credited account is cash, because cash is reduced by $100, while the office supplies account is debited by the same value.
If a firm sells 100$ of office supplies instead, the office supplies inventory is credited for this value, while the same amount of cash is debited for this same amount.
Answer:
d) competitors are similar to monopolists.
Explanation:
Monopolistic competition refers to a condition of the market in which it connects with various irms that are closely linked to each other but sell distinct products.
Also, there is free entry and exit in this market
In case when consumer taste and preferences are different so the monopolistic competitors are the same as the monopolist
hence, the correct option is d.
