Answer:
Standard deviation = 47.69% (Approx)
Explanation:
Given:
Portfolio of Apple stock w1 = 25% = 0.25
Portfolio of Tesla stock w2 = 75% = 0.75
Standard deviation return Apple σ1 = 35% = 0.35
Standard deviation return Tesla σ2 = 60% = 0.60
Correlation coefficient ρ12 = 0.22
Find:
Standard deviation
Computation:
Standard deviation = √w1²σ1² + w2²σ2² + 2w1σ1w2σ2ρ12
Standard deviation = 0.4769
Standard deviation = 47.69% (Approx)

A broad principle that requires identifying the activities of a business with specific time periods such as months, quarters, or years is the <u>Time period principle.</u>
The time period principle- Financial results and other material business activities should be reported over a consistent time period, such as a month, week, day, etc., in accordance with the time period concept. Depending on the frequency of the chosen time period, the firm must then adhere to a distinct set of regulations for each financial statement in accordance with US Generally Accepted Accounting Principles.
Any company's financial statements can be thought of as a snapshot in time that reveals both the company's history and its current status. That's why it's crucial to disclose to readers the time frame in which the financial statements were generated in accordance with the time period concept.
In its broadest sense, the time period principle holds that any enterprise may conveniently categorize its financial operations into discrete time intervals. That is to say, all cash inflows and outflows may be neatly categorised into separate and sequential accounting periods.

Answer:
<em>Documentary evidence </em>
Explanation:
<em>CFAs resolve fraud allegations by taking statements, obtaining evidences and writing reports, testifying crimes and by assisting in the detection and prevention of white collar crimes. </em>
Any evidence that can be used at a trial as documents are called documentary evidence, it generally means the wrings on paper such as a will, contract or invoice. Tape recordings, photographs printed documents, emails and spreadsheets can also be considered documentary evidence. Although authenticity of genuine evidence needs to be proved
If a document is produced for other purpose instead of the examination of the contents of the document it is not considered to be a documentary evidence.
e.g if a letter is produced during the trial to prove that the author of letter was shot by the defendant then it would be considered as documentary evidence but a film of the incident or a written description of this incident by an eye witness would be considered as documentary evidence.
Cost of equity capital is closest to: 16 percent
Solution:
WACC is covered on page 120 Corporate Finance, under Capital Structure.
Using the standard equation for WACC = %wt Equity x cost of equity (re) + %wt Debt x cost of debt (rd).
Since there is a 20% tax rate for the firm, the cost of borrowing is reduced by that amount. So the cost of debt is 4%, not 5%.
Plug the formula: 10% = 50% x re + 50% x 4%
The formula ( i.e. 0.1+(0.1-0.05)(1)(1-0.2)) in CFAI reading is questionable.
The calculation is 0.1+(0.1-0.05*(1-0.2))*(1)=16%
