Answer:

Variance = 0.02141851

Explanation:

We first calculate the mean for the stocks

Mean = (0.1858 - 0.0558 + 0.2081) / 3

Mean = 0.3381 / 3

Mean = 0.1127

Variance = [(0.1858 - 0.1127)^2 + (- 0.0558 - 0.1127)^2 + (0.2081 - 0.1127)^2] / 3 -1

Variance = [0.0731^2 + (-0.1685^2) + 0.0954^2] / 2

Variance = 0.00534361 + 0.02839225 + 0.00910116 / 2

Variance = 0.04283702 / 2

Variance = 0.02141851

The variance of returns is 0.02141851

kkurt [141]

Answer:

17.76%

Explanation:

The computation of the time-weighted return on your investment is given below

But before that we have to do the following calculations

Year 1 = ($46.50 - $42.50) + 2 ÷ ($42.50) × 100 = 14.12%

Year 2 = ($54.50 - $46.50) + 2 ÷ ($46.50) × 100 = 21.51%

Now the time weighted return is

(1 + t)^2 = (1 + 14.12%) × (1 + 21.51%)

= 1.1412 × 1.2151

= √1.3867 - 1

= 17.76%

Identify the internal control weakness in the following situations. State how the person can hurt the company.
Degger [83]

Answer:

Identification of the Internal Control Weaknesses:

A.  There is no segregation of duties and there is lack of access control.  Jerry Miller as a security guard is not expected to have a master key to the cash box.  With this he can pilfer the cash.  If he prepares the report that shows the number of cars that parked on the lot, he is not supposed to also prepare the day's cash receipts.  Otherwise, he can state any number of cars as parked that he likes, and which corresponds to the cash he might leave in the Cash box since he also has a master key.

B.  There is no segregation of duties and there is lack of supervision,  proper reconciliations, and assets audit.  Sharon Fisher handles purchase transactions from the beginning to the close all alone with a third party.  This exposes the company to procurement frauds and collusion with suppliers.  She can purchase assets for the company at prices that would enrich her personally.

C. Forming an audit opinion on the basis of ratio analysis of last year's comparative financial statements exposes the company to audit risks.  While ratio analysis is part of the basis for forming audit opinions, it is surely not the first audit procedure to obtain audit evidence to support his audit opinion on the financial statements.  An auditor is expected to obtain sufficient audit evidence and perform audit substantive tests of financial statement assertions.  He or she is also expected to review the internal control system to ensure that it is operating effectively after establishing its existence and reviewing changes in internal controls.

Explanation:

Internal Controls are controls established by management in order to help it achieve business goals.  There are many internal controls, including Separation of Duties, Access Controls , Authorization and Approvals, Asset Audits, Reconciliations, and Data Backups.  The purposes of internal controls are to establish the reliability of financial reporting, ensure timely feedback on the achievement of operational or strategic goals, and achieve compliance with financial management laws, and accounting regulations.

The natural rate of unemployment:_______. a. means that the economy will always operate at that rate. b. is equal to the total o
blsea [12.9K]

Answer:

B. is equal to the total of frictional and structural unemployment.

Explanation:

The natural rate of unemployment is the sum of frictional and structural unemployment at any given time. Economists estimate that for the United States this rate is around 3.5%.

Unemployment has a natural rate because no matter how good the economy is doing, some people either do not want to work, are in between jobs (frictional unemployemt), or lack the skills necessary to get employed and need to undergo training (structural unemployment).
