Answer:
Have the highest risk and rates of return and the highest standard deviations.
Explanation:
The efficient portfolios of N risky operatives is the set of optimal portfolios that offer the highest expected return for a defined level of risk or the lowest risk for a given level of expected return. And in other words, portfolios that lie below the efficient frontier are been described as sub optimal because they do not provide enough return for the level of risk. Portfolios that cluster to the right of the efficient frontier are sub optimal because they have a higher level of risk for the defined rate of return.
Answer:
e. Control and Results
Explanation:
The other two principles of Google Ads are explained below:
1. Control: There is control on the scale you want to advertise and the budget you spend on campaigns. This is configured in Google Ads settings and enables tailoring to available budget.
2. Results: This is also connected to control. Users only pay for Google services used. For example if an advertisement is set up payment is only made when clicks are made to access it (pay per click).
Also the same applies to pay per call, where payment is only made when calls are attributed to Google Ads.
Answer: double coincidence of wants
Explanation:
Coincidence of wants simply refers to a situation whereby two parties have something that the other person wants, therefore they then exchange the products they have. It should be noted that no financial compensation is involved. This simply has to do with trade by barter.
If William performs plumbing upgrades for Patricia in exchange for her incorporating his business, then their double coincidence of wants will be satisfied.
Answer:
there are 59 nickels, 12 quarters, and 213 dimes
Explanation:
- let n = nickels
- let q = quarters
- let d = dimes
first step:
d = 3 (n + q) = 3n + 3q
d + n + q = 284
0.10d + 0.05n + 0.25q = 27.25
second step:
3n + 3q + n + q = 284
0.10 (3n + 3q) + 0.5n + 0.25q = 27.25
third step:
4n + 4q = 284
0.3n + 0.3q + 0.05n + 0.25q = 27.25
fourth step:
n + q = 71
0.35n + 0.55q = 27.25
fifth step:
replace q = 71 - n
0.35n + 0.55(71 - n) = 27.25
sixth step:
0.35n + 39.05 - 0.55n = 27.25
seventh step:
11.8 = 0.2n
eighth step:
n = 59
q = 71 - 59 = 12
d = 284 - n - q = 284 - 59 - 12 = 213
