Answer: $1000
Explanation:
You didn't give the options but let me help out.
From the question, we are informed that Hi Phi Unlimited's total revenue from installing 15 sound systems is $30,000 and its total revenue from installing 18 sound systems is $33,000.
The marginal revenue that is received from selling the 18th sound system would be calculated as:
=($33000 - $30000) / (18 - 15)
= $3000 / 3
= ,$1000
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:
Type A is 7%, type b is 11%
Explanation:
We have these two firm's as type a and type b
For type A
Interest would be = risk Free rate of 2% + risk free rate of 5% = 7%
For type B
= Risk free rate of 5% + risk free rate of 6% = 11%
I would use the average of this two 9% as interest but this is not going to work for type A because this interest rate is too high. People won't want to pay this much.
Decentralization refers to the degree to that decision-making is concentrated to the top of the organization: False.
<h3>What is a
decentralized organization?</h3>
In a decentralized organization, the decision-making authority and power isn't concentrated at the top level (echelon) of the organization.
This ultimately implies that, decentralization refers to the degree to that decision-making is concentrated to all the areas of an organization.
