The question is incomplete. Here is the complete question:
The following annual returns for Stock E are projected over the next year for three possible states of the economy. What is the stock’s expected return and standard deviation of returns? E(R) = 8.5% ; σ = 22.70%; mean = $7.50; standard deviation = $2.50
State Prob E(R)
Boom 10% 40%
Normal 60% 20%
Recession
30% - 25%
Answer:
The expected return of the stock E(R) is 8.5%.
The standard deviation of the returns is 22.7%
Explanation:
<u>Expected return</u>
The expected return of the stock can be calculated by multiplying the stock's expected return E(R) in each state of economy by the probability of that state.
The expected return E(R) = (0.4 * 0.1) + (0.2 * 0.6) + (-0.25 * 0.3)
The expected return E(R) = 0.04 + 0.12 -0.075 = 0.085 or 8.5%
<u>Standard Deviation of returns</u>
The standard deviation is a measure of total risk. It measures the volatility of the stock's expected return. The standard deviation (SD) of a stock's return can be calculated by using the following formula:
SD = √(rA - E(R))² * (pA) + (rB - E(R))² * (pB) + ... + (rN - E(R))² * (pN)
Where,
- rA, rB to rN is the return under event A, B to N.
- pA, pB to pN is the probability of these events to occur
- E(R) is the expected return of the stock
Here, the events are the state of economy.
So, SD = √(0.4 - 0.085)² * (0.1) + (0.2 - 0.085)² * (0.6) + (-0.25 - 0.085)² * (0.3)
SD = 0.22699 or 22.699% rounded off to 22.70%
Answer:
E. separation, self-service, automation, and scheduling.
Explanation:
Increase in productivity in a business aims to increase the efficiency of an individual or process involved in production of useful output.
Strategies for improving productivity includes separation, self-service, automation, and scheduling.
When there is seperation in services available to a customer, they easily identify the most relevant one to them.
Self service gives control of the process to the customer, resulting in greater satisfaction.
Automation reduces the turnaround time of processes and refocuses labour to more complex activities. So production efficiency increases.
Scheduling reduces time wastage by assigning time to complete activities.
Answer: C
Explanation: average total cost is at its minimum
Andy just purchased a 2.5 acre vacant lot of land for $500,000. $41.32 per sq. yd price per square yard.
$500,000 ÷ 12,100 sq. yds. = $41.32 per sq. yd
What is square yard?
- The length times the width, expressed in feet, must be multiplied by 9, and the result is the square yard (SQYDS). A square yard measures 9 square feet.
- One billion is referred to as "yard" in finance. The word is derived from "milliard," which is comparable to the number one billion in American English and is used in various European languages.
- Add the area to the conversion factor to convert a square yard measurement to a square foot measurement. The square yards multiplied by nine gives the area in square feet.
- Add the length to the conversion factor to convert a yard measurement to a meter measurement. The yards times 0.9144 converts to the length in meters.
