Answer:
The portfolio SD is A. 20.65%
Explanation:
The standard deviation tells the total risk (both systematic and unsystematic) associated with a stock or a portfolio. The portfolio risk or the standard deviation of portfolio can be calculated using the following formula as attached in the picture below.
Using this formula, the standard deviation of the portfolio is:
SDp = √(0.3)² * (0.2)² + (0.7)² * (0.25)² + 2 * (0.3)*(0.7) * 0.4 * (0.2)*(0.25)
Portfolio SD = 0.20645 or 20.645% rounded off to 20.65%
This is an example of agency by ratification. This rises when an individual (the principal) approves (that is, ratifies and adopts) an act which has already been completed in his name and on his behalf by the agent, who actually, had no real authority (whether spoken or indirect) to act on the principal's behalf when the performance was completed.
Answer:
295 units of Qa
and 129 untis of Qb
Explanation:
1/4Assembly hours x Qa + 1/3Assembly hoursx Qb = ASH
1/8 testing hours x Qb+ 1/3 testing hours x Qb = TSH
Profit = 9 x Qa + 8 x Qb
Assembly hours <= 90
testing hours <= 80
We also has to make the cosntrain that units should be integer as we cannot do half a unit.
<u>We build this in solver to get the max profit.</u>
A B C D
Units Assembly Testing Profit
295 0.25 0.125 9
129 0.125 0.33 8
89.88 79.88 3,687.00
(295 x 0.25 + 129 x 0.125)
(295 x 0.125 + 129 x 0.33)
(295 x 9 + 129 x 8)
