Answer:

Option d. Is the correct answer.

Explanation:

We are given

Wa = 40/100

Wa = 0.4

Wb = 60/100

Wb = 0.6

We are also give given the covariance as a,b

a² = 144

b² = 81

Therefore, the covariance will be

Cov(a,b) = 225

Portfolio Variance:

Variance =

(0.4×0.4×144) + (0.6×0.6×81) + (2×0.4×0.6×225)

Variance = 23.04 + 29.16 + 108

Variance = 160.2

Remember that, standard deviation is the square root of variance which we have has

Standard Deviation of the portfolio =√160.2

Standard Deviation of the Portfolio = 12.7

Answer:

A portfolio consists of 40% in Security A and 60% in Security B. The covariance matrix for A is 144, 225; for B is 225, 81. The standard deviation for the portfolio is <u>12.7</u>

Option D is correct

Explanation:

Wa: 0.4

Wb: 0.6

a^2: 144

b^2: 81

Cov(a,b): 225

Portfolio Variance:

: (0.4*0.4*144) + (0.6*0.6*81) + (2*0.4*0.6*225)

: 160.2

Portfolio Standard Deviation: 12.7

ABC Company sold the rights to use one of their patented processes that will result in them receiving cash payments of $10,000 a
BigorU [14]

Answer:

$77,217

$11,289

Explanation:

Fist we will calculate the present value of $10,000 payment

A fix Payment for a specified period of time is called annuity. The discounting of these payment on a specified rate is known as present value of annuity. The value of the annuity is also determined by the present value of annuity payment.

Formula for Present value of annuity is as follow

PV of annuity = P x [ ( 1- ( 1+ r )^-n ) / r ]

Where

P = Annual payment = $10,000

r = rate of return = 10% / 2  = 5%

n = number of period = 5 years x 2 semiannual payments per year = 10 payments

PV of annuity = $10,000 x [ ( 1- ( 1+ 0.05 )^-10 ) / 0.05 ]

PV of Annuity = $77,217

Now we will use the discounting method to calculate the present value of lump sum payment of $20,000

Present value = Future value x Present value factor

PV = FV x ( 1 + r )^-n

PV = $20,000 x ( 1 + 0.1 )^-6

PV = $11,289

When making scrap or rework decisions, management should consider: (Check all that apply.)a. Revenue from selling defective unit
vlabodo [156]

Answer:

The correct answer is all of the above

Explanation:

Scrap or the rework costs are the costs which is incurred in order to repair the   items that are defective. And the decision to rework or scrap an item or product, ground on the benefits or advantage of the incremental costs.

If the reworked units generate or yield greater advantage or benefit rather than the selling them as scrap, then the decision to rework will be considered.

And if the decision of rework is taken, then the management should consider the incremental costs, revenue or profit from selling the defective units as scarp and the lost profit on selling and making the new units while the rework is performed.

c. $1.4 Billion

d. $100 Million

The correct option is A,$200 million

The increase in cash recorded from the statement of cash flows prepared in the year plus the opening balance of cash at the beginning of the year gives the cash balance at the end of the year shown below:

Increase in cash in the year=cash flow from operations+cash flow from financing activities-cash flow used on investing activities

increase in cash in the year=$325+($500-$100)-$600=$125  million

cash at the end of the year=$125 +$75=$200 million

there is some concern that increased use of could prompt the need for legislation protecting employee privacy rights.
djyliett [7]

There is some concern that increased use of electronic databases could prompt the need for legislation protecting employee privacy rights.

An electronic database is a computer-based collection also listing of the information. Through this the information can be searched in a fast and easy manner.

Electronic databases held organized collections of data, or information, which is thus stored in a computer in a readable form. So sometimes, the increased use of electronic databases might probably prompt the need for legislation which protects employee privacy rights.

Hence, the electronic databases can make it easier to search, query, filter and retrieve required data.
