Answer:
Expected return is: 7.37% and the Standard deviation is: 24.96%
Explanation:
Correlation between fund S&B=0,0667
Standard Deviation of Fund S=41%
Standard Deviation of Fund(B)=30%
E(R) of Stock Fund S=12%
E(R) of Stock Fund B=5%
Covariance between the funds = Standard Deviation of Fund(B) × Standard Deviation of Fund S × correlation between these funds
Cov = 0.41 × 0.30 × 0.0667 = 0.008204
Now minimum variance portfolio is found by applying:
W min(S)=(SDB)^2-Cov(B,S) / ((SDS)^2+(SDB)^2-2Cov(B,S)
W min(S) = 0.338431
W min(B) = 1-0.338431=0.661569
1) E(r)min= 0.338431 × 12% + 0.661569 × 5% = 7.37%
2) Standard Deviation:
SD Min = (Ws^2XSDs^2+Wb^2XSDb^2+2XWsWb*Cov(s,B)^1/2
SDmin=(0.338431^2 × 0.41^2 + 0.661569^2 × 0.3^2 + 2 × 0.338431 × 0.661569 × 0.008204)^1/2
SDmin=24.96%
Answer:
c. $36,070
Explanation:
contribution margin ratio is the ratio of the contribution to sales of an entity for a given period.
contribution margin ratio= contribution/sales
where contribution is the difference between sales and the variable cost
Given;
sales = $137,000
contribution margin ratio = 61% = 0.61
0.61 = contribution/$137,000
contribution = $137,000 × 0.61
= $83,570
Net operating income is the difference between the contribution and the fixed cost.
Fixed cost = $47,500
Net operating income = $83,570 - $47,500
= $36,070
Answer:
Options C and E
Only Nick and Jake are optimising over his choice of fruit?
Explanation:
The marginal utility obtained from the purchase of a product is the amount of satisfaction derived from purchasing an additional unit of the product.
The utility is maximised when the satisfaction in terms of marginal utilities obtained from each product is equal to each other.
We obtain this simply by dividing the marginal utilities for each fruit by their price, and comparing them.
Dmitiri:
Apples: 8/1 =8
Pears: 10/2 =5
8/1 is not equals to 10/2
Frances:
Apples: 7/1 =7
Pears: 16/2 =8
7 is not equals to 8
Jake:
Apples: 6/1 =6
Pears: 12/2 =6
The marginal utility is equal hence Jake's choice is optimal
Latasha:
Apples: 5/1 =9
Pears: 9/2 =4.5
9 is not equals to 4.5
Nick:
Apples: 4/1 =4
Pears: 8/2 =4
The marginal utility is equal hence Nick's choice is optimal
Answer:
(d) Straight-line method (SL), the same convention as used in the first year of depreciation, ADS recovery period
Explanation:
The straight line method is the best to use, the convention to be used is the same as what was used in the first year of depreciation and the recovery period in 2019 is the ADS recovery period.
To decrease annual deduction, it is standardized that ADL is used with straight line method with 31 plus years for a recovery period that is longer.
Answer:
Sequential interdependence on the line to pooled interdependence between the teams
Explanation:
Sequential interdependence occurs when a persons output is necessary for the performance of the next persons input. Perhaps the most obvious example of sequential interdependence is an assembly line.
While pooled interdependence he team accomplishes its tasks simply by bringing together everyone’s separate efforts. Like in DamierChrystern when the team work together to build the total car with the team deciding whi does what task. To be a team you need a team task — it requires that members actively work with each other to accomplish it
