A process that produces computer chips has a mean of .04 defective chip and a standard deviation of .003 chip. The allowable variation is from .03 to .05 defective. a. Compute the capability index for the process. b. Is the process capable?

Answers

Answer 1
Answer:

Answer:

A. 1.111

B. The process is not capable

Explanation:

Part A

Capacity index help todetermine the performance of a process and how it could perform in the future. A capacity index of above 1.33 means that the process is capable but a capacity index below 1.33 means that the process is not capable. The capacity index can be calculated using equation 1;

From the mean  which is 0.5, it can be determined that the process is a centered process.

For centered process, the mean = 0.5 x (Upper s. - Lower S.) = 0.5 x 0,02 = 0.04

so the capacity index for centered mean will be used

C_(p) =(Upper Specification-Lower Specification)/(6 * standard deviation) ................................................1

Given standard deviation = 0.003

upper specification = 0.05

lower specification = 0.03

C_(p) =(0.05- 0.03)/(6 * 0.003)\n\nC_(p) = (0.02)/(0.018) \n\nC_(p)  = 1.111

Therefore the capacity index of the process is 1.111

Part B

The capacity index of the process is 1.111 and it is less than 1.33, this means that the process is not capable.

At December 31, 2018, Novak Corp. Company had a credit balance of $ 18,000 in Allowance for Doubtful Accounts. During 2019, Novak Corp. wrote off accounts totaling $ 13,300. One of those accounts ($ 3,200) was later collected. At December 31, 2019, an aging schedule indicated that the balance in Allowance for Doubtful Accounts should be $ 27,200. Prepare journal entries to record the 2019 transactions of Novak Corp. Company

Answers

Answer:

Explanation:

The journal entries are shown below:

1. Allowance for Doubtful Accounts A/c Dr $ 13,300

      To Accounts receivable A/c $ 13,300

(Being written off amount is recorded)

2. Accounts receivable A/c Dr  $3,200

      To  Allowance for Doubtful Accounts A/c $3,200

(Being reverse written off)

3. Cash A/c Dr  $3,200

        To Accounts receivable A/c  $3,200

(Being amount collected)

4. Bad debt expense A/c Dr   $19,300

           To Allowance for doubtful debts   $19,300

(Being bad debt expense is recorded)

The computation of the bad debt expense is shown below:

Ending balance of Allowance for Uncollectible Accounts = Beginning balance of Allowance for Uncollectible Accounts + 2019 bad debts - 2019 write off amount  + collected amount

$27,200 = $18,000 + 2019 bad debts - $13,300 + $3,200

$27,200 = $7,900+ 2019 bad debts  

So,2019 bad debts = $27,200 - $7,900 = $19,300

Calculate the contribution margin and the contribution margin ratio. (Round your contribution margin to the nearest dollar, and your contribution margin ratio to two decimal places.)

A) $38,650; 48.31% B) $74,850; 93.56%

C) $60,650; 75.81% D) $32,950; 41.19%

Answers

Answer:

A) $38,650; 48.31%

Explanation:

The computation of the contribution margin and the contribution margin ratio is shown below:

Contribution margin = Service Revenue - Cleaning Supplies Used - wages expense

= $80,000 - $22,000 - $19,350

= $38,650

The variable cost is Cleaning Supplies Used + wages expense

And, the contribution margin ratio equals to

= (Contribution margin ÷ sales) × 100

= ($38,650 ÷ $80,000)  × 100

= 48.31%

Sheridan Company signed a three-month, zero-interest-bearing note on November 1, 2020 for the purchase of $497000 of inventory. The face value of the note was $509000. Sheridan used a "Discount of Note Payable" account to initially record the note. Assuming that the discount will be amortized equally over the 3-month period and that there was no adjusting entry made for November, the adjusting entry made at December 31, 2020 will include aa. debit to Discount on Note Payable.b. debit to Interest Expense .c. credit to Discount on Note Payable.d. credit to Interest Expense.

Answers

Answer:

Explanation:

The journal entry to record the note payable at discount

Cash A/c Dr $497,000

Discount on Note payable A/c  Dr $12,000

               To Note Payable A/c $509,000

(Being the note payable is recorded at discount)

Now we know that the discount is for 3 months but we have to calculated for 2 months only i.e from November 1 to December 31

So, the discount would be

= $12,000 × 2 months ÷ 3 months

= $8,000

And the journal entry is

Interest Expense A/c Dr $8,000

           To Discount on Note payable A/c $8,000

(Being the interest expense is recorded)

The owner of Showtime Movie Theaters, Inc., would like to predict weekly gross revenue as a function of advertising expenditures. Historical data for a sample of eight weeks follow. The owner then used multiple regression analysis to predict gross revenue (y), in thousands of dollars, as a function of television advertising (x1), in thousands of dollars, and newspaper advertising (x2), in thousands of dollars. The estimated regression equation was ŷ = 83.2 + 2.29x1 + 1.30x2. (a) What is the gross revenue (in dollars) expected for a week when $4,000 is spent on television advertising (x1 = 4) and $1,500 is spent on newspaper advertising (x2 = 1.5)? (Round your answer to the nearest dollar.)

Answers

Answer:

Y = 83.2 + 2.29x1  + 1.30x2

Y = 83.2 + 2.29(4) + 1.30(1.5)

Y = 83.2 + 9.16 + 1.95

Y = 94.31(thousand)

Y = $94,310

The gross revenue is $94,310

Explanation:

In this case, the estimated regression equation has been given.  Since x1 is $4,000 and x2 is $1,500, then, we will substitute these values for x1  and x2 in the equation. The addition of all values after the substitution gives the gross revenue.

At the start of the year, your firm's capital stock equaled $100 million, and at the end of the year it equaled $105 million. The average depreciation rate on your capital stock is 20%. Gross investment during the year equaled A) $1 million B) $5 million. C) $7 million D) $25 million

Answers

Answer:

The answer is D.

Explanation:

Net investment equals Gross investment minus depreciation.

Net investment equals Investment at the beginning of the year minus Investment at the end of the year.

Net investment = $105 million - $100 million.

Net investment = $5million.

Depreciation = 20% of investment at the start of the year

= 20% of $100million

= $20million.

Gross investment is therefore,

$5million + $20million

=$25 million

Answer:

Option D,$25 million is the correct answer.

Explanation:

The net investment formula can be used to compute gross investment by changing the subject of the formula as shown below:

Net investment = gross investment minus depreciation

Net investment =Closing capital stock minus opening capital stock

closing capital stock is $105 million

opening capital stock is $100 million

net investment=$105 million-$100 million=$5 million

Gross investment is unknown

depreciation=opening capital stock* depreciation %

depreciation=$100 million*20%

                     =$20 million

$5 million=gross investment-$20 million

gross investment =$5 million+$20 million

gross investment =$25 million

Resources are distributed unevenly throughout the world. This fact MOST relates to the reasons for A.profit seeking.
B.free enterprise.
C.international trade.
D.business competition.

Answers

Answer:

C.international trade

Explanation:

In business, resources are tangible materials used in the production process. Natural resources are valuable materials found beneath,  above, or on the earth's surface. These materials are naturally occurring and are distributed unevenly across the globe. They include Minerals, forests, fertile lands, water, oil and gas, plants, and animals.

Some resources, such as minerals and water, become raw materials, while others, such as land, facilitate the production process. Because resources are unevenly distributed, regions with plenty can use them to produce goods and services and sell to areas with scarcity. No single region has the resources it requires. International trade makes it possible for regions to sell what they have in plenty and buy what they luck.
