Answers

Answer 1

Solution :

The average number of the arrivals, λ = 6 per hour

Average service rate, [tex]$\mu = \frac{60 \times 2}{15}$[/tex]

                                      = 8

Average number of the customers in the system is given by,

    [tex]$= \frac{\lambda}{\mu - \lambda }$[/tex]

   [tex]$= \frac{6}{8 - 6 }$[/tex]

  = 3

Average number of the customers that are waiting in the line behind the person who are being served is,

   [tex]$=\frac{\left(\frac{\lambda}{\mu}\right)^2}{1-\frac{\lambda}{\mu}} $[/tex]

  [tex]$=\frac{\left(\frac{6}{8}\right)^2}{1-\frac{6}{8}} $[/tex]

 [tex]$=\frac{(0.75)^2 }{0.25} $[/tex]

  = 2.25

Proportion of the time the server is busy,

    [tex]$=\frac{\lambda}{\mu}$[/tex]

   [tex]$=\frac{6}{8}$[/tex]

   = 0.75

Park Hyatt Philadelphia has 118 king/queen rooms that it offers to both leisure and business travelers. With leisure travelers in mind, the Hyatt offers a $125 low fare for a midweek stay, which contrasts with the regular fare of $300. The forecasted demand for business travel is normally distributed with a mean of 60 customers and standard deviation of 20 customers. Assuming that leisure travelers always reserve their rooms earlier than business travelers. To maximize the revenue, the Hyatt decides to save some rooms for business travelers. The optimal number of rooms protected should be:__________ a. <60 b. >118 c. >60 d. =60

Answers

Answer:

c. >60

Explanation:

Given that:

Overage (CO) = 125

Shortage (CS) = 300

The Service level = [tex]\dfrac{CS}{CS+CO}[/tex]

[tex]=\dfrac{300}{300+125}[/tex]

[tex]=\dfrac{300}{425}[/tex]

= 0.7059

The Z value of 0.7059 is 0.55

where;

the mean [tex]\mu[/tex] = 60

the standard deviation [tex]\sigma[/tex]= 20

Optimal booking = [tex]\mu +(Z \times \sigma)[/tex]

Optimal booking = 60 + (0.55 × 20)

Optimal booking = 60 + 11

Optimal booking = 71

What was the impact of "subprime" mortgages on the economy?

A.They increased defaults and caused large losses at financial institutions.

B.They initially reduced profits and sales of lenders.

C. They reduced interest rates.

Answers

Answer:

A.They increased defaults and caused large losses at financial institutions.

Explanation:

'Subprime" mortgages were home homes offered in the early 2000s to borrowers with low and poor credit history. By the time of issues, the interest rates were relatively low, which meant that subprime borrowers who usually attract high-interest rates were approved for mortgages. The demand for housing grew exponentially as borrowers with good and poor credit history alike tool mortgages. The price for houses continued to rise, prompting the Fed to raise the interest rate to contain inflation.

Between 2205 and 2006, house prices collapsed suddenly. Interest rates were rising, but house prices were dropping. Many homeowners were unable to repay their mortgages. The interest and principle there are paying were very high compared to the market value for the homes. There were massive layoffs by subprime mortgage lenders, while others closed down or applied for bankruptcy. The decline in prices implied that the mortgage value was high compared to the market price for houses.

Brief Exercise 229 Iverson Company purchased a delivery truck for $45,000 on January 1, 2020. The truck was assigned an estimated useful life of 5 years and has a residual value of $10,000. Compute depreciation expense using the double-declining-balance method for the years 2020 and 2021.

Answers

Answer:

the  depreciation expense using the double-declining-balance method for the years 2020 and 2021 is $18,000 and $10,800 respectively

Explanation:

The computation of the depreciation expense using the double declining method for the year 2020 and 2021 is as follows:

For 2020

= (Cost) × depreciation rate

= $45,000 × 1 ÷ 5 × 2

= $18,000

For 2021

= ($45,000 - $18,000) × 0.40

= $10,800

hence, the  depreciation expense using the double-declining-balance method for the years 2020 and 2021 is $18,000 and $10,800 respectively

Required: Using Straight-line depreciation method, what is the annual depreciation expense

Answers

Answer:

the yearly depreciation expense is $5,500

Explanation:

The computation of the yearly depreciation expense using the straight line method is as follows;

= (Purchase cost - salvage value) ÷ (estimated useful life)

= ($24,000 + $800 + $1,200 - $4,000) ÷ (4 years)

= ($26,000 - $4,000)  ÷ (4 years)

= $22,000 ÷  4 years

= $5,500

hence, the yearly depreciation expense is $5,500

On September 1, 2019, Parker, Inc. made a loan to one of its customers. The customer signed an 8-month note for $105,000 at 14%. Calculate the maturity value of the note. (Round any intermediate calculations to two decimal places, and your final answer to the nearest dollar.)

Answers

Answer:Maturity value =$115,000

Explanation:

Maturity value is the amount that includes the principal and accrued interest  that  a borrower should pay on  its maturity date.

Maturity value of note = Principal  + interest accrued

Interest = Principal x rate x time

=$105,000 x 14% X 8/12

=$9,800

Maturity value = $105,000 + 9,800

=$114,800

rounding up to the nearest dollar≈$115,000

Hardwoods, a timber supplying company, contracted with a furniture manufacturer, Taylor Furniture. Hardwoods owned a large plot of land where it grew oak and beech trees. Taylor had contracted with Hardwoods to buy one ton of each type of lumber grown by Hardwoods each month at a discounted price for the next five years. However, during the second year of the contract, and tornado Hardwoods farmland, and demolished its entire supply of wood. Taylor having no other supplier sued Hardwoods for breach of contract. Hardwoods argued that their contract had been legally discharged as soon as the tornado struck because at that point it was impossible for Hardwoods to supply lumber to Taylor. The court ruled in favor of Hardwoods. But what if the facts of the case were different

Answers

Answer:

the options are missing, so I looked for a similar question:

Instead of a tornado’s striking Hardwoods’ land, the state in which Hardwoods operates passes a law making it illegal for any lumber  companies to cut down trees for the purposes of selling their wood. This environmental measure causes Hardwoods to go out of business. Instead of demanding Oak and Beech wood grown specifically on Hardwoods’ land, Taylor requests shipments of Oak and Beech wood  from Hardwoods, and specifies in the contract that if Hardwoods cannot supply the wood, then Hardwoods should obtain the requested wood from another lumber supplier. Instead of a tornado’s striking Hardwoods’ tree farm, a wildfire burns all of Hardwoods’ trees. After the tornado, Hardwoods and Taylor Furniture agree to a novation, whereby a competing company, Oakempire, assumes the duties of  Hardwoods stated in the original contract.

The answers are:

2. Instead of demanding Oak and Beech wood grown specifically on Hardwoods’ land, Taylor requests shipments of Oak and Beech wood  from Hardwoods, and specifies in the contract that if Hardwoods cannot supply the wood, then Hardwoods should obtain the requested wood from another lumber supplier.

4. After the tornado, Hardwoods and Taylor Furniture agree to a novation, whereby a competing company, Oakempire, assumes the duties of  Hardwoods stated in the original contract.

Explanation:

In common law, a tornado or any other type of natural disaster is considered an Act of God. A company cannot be held liable for such events, and if a contract is breached because of it, there is no legal responsibility (option 3 is another type of Act of God)

Also, if the law or existing regulation changes, and that change makes it impossible for a party to fulfill their obligations, they are not liable for breaching the contract (option 1).

The data below summarize the department's operations in January. The accounting records indicate that the conversion cost that had been assigned to beginning work in process inventory was $5,096 and a total of $87,668 in conversion costs were incurred in the department during January. What was the cost per equivalent unit for conversion costs for January in the Molding Department

Answers

Answer:

$1.752  per unit

Explanation:

The computation of the cost per equivalent unit for conversion cost is as follows:

Total conversion cost for month of January

= Opening wip conversion cost + current production conversion cost

= $5,096 + $87,668

= 92,764

Now the total equivalent units is

= Units transferred out + ending wip

= 51,300 × 100% + 5,500 × 30%

= 52,950 units

Now the cost per equivalent unit is

= $92,764 ÷ 52,950 units

= $1.752  per unit

What is the modified duration of a four-year bond with annual 10% coupons and a 10% yield to maturity?

Answers

Answer:

the formula to calculate modified duration of bonds:

modified duration = [1 - (1 + y)⁻ⁿ] / y

modified duration = [1 - (1 + 10%)⁻⁴] / 10%  = 0.317 / 10% = 3.17 years

is global economic resistance good or bad?​ why?​

Answers

Answer:

The global economy can be a little frustrating because globalization and the global economy are terms that mean different things to different people. I have found that some people talk about the global economy and what they mean is the opening of markets and trade among nations—so that today you can buy products in a store that have been made everywhere around the world, and people everywhere around the world are buying products that we make.

That didn’t used to be the case, partly because transportation and communication technologies were inadequate and partly because there were a lot more political barriers and even wars going on that prevented people from trading with each other. But in the twentieth century—especially in the late twentieth century—there’s been a large-scale dismantling of political barriers to trade combined with a dramatic increase in communication and transportation technology that has opened up a new global market.

Answers

Answer:

net cash provided by investing activities $22,800

Explanation:

the carrying value of the equipment = $80,500 - $48,400 = $32,100

the sales price of the equipment was $32,100 + $3,600 (gain on sale) = $35,700

land was purchased for $10,900

available for sale securities were purchased fro $2,000

total cash flows from investing activities = $35,700 (cash proceeds from sales of equipment) - $10,900 (land purchased) - $2,000 (AFS securities purchased) = $22,800

If you purchase 100 shares of XYZ Corporation for $50 per share, receive a dividend check for $200, and then sell the stock for $62 per share, what will your return on the stock be

Answers

Answer:

Your return on the stock will be 28%.

Explanation:

Po = Initial price per share = $50

P1 = New price per share = $62

S = Number shares purchased = 100

D = Dividend per share = Dividend received / Number shares purchased = $200 / 100 = $2

Therefore, we have:

Stock return = ((P1 - Po) + D) / Po = (($62 - $50) + $2) / $50 = ($12 + $2) / $50 = $14 / $50 = 0.28, or 28%

Therefore, your return on the stock will be 28%.

Materials used by Jefferson Company in producing Division C's product are currently purchased from outside suppliers at a cost of $10 per unit. However, the same materials are available from Division A. Division A has unused capacity and can produce the materials needed by Division C at a variable cost of $7.50 per unit.

How much would Jefferson's total income from operations increase

Answers

Answer:
