Suppose that the average time before breakdown is normally distributed with a mean of 2.5 weeks and a standard deviation of .4 weeks. If breakdowns cost an average of $1,200 and preventive maintenance costs $800, what is the optimal maintenance interval

Answers

Answer 1

Answer:

2.67 weeks

Explanation:

Optimal maintenance is the discipline within operations research concerned with maintaining a system in a manner that maximizes profit or minimizes cost.

DATA

Preventive Cost = 1200

Breakdown cost = 800

Ratio = Preventive cost / breakdown cost

Ratio = 1200 / 800

Ratio = 0.67

Z value for 0.67 = 0.44

Optimal maintenance interval = Mean time + Z(Standard deviation)

Optimal maintenance interval = 2.5 + 0.44(0.4)

Optimal maintenance interval = 2.5 + 0.176

Optimal maintenance interval = 2.67 weeks

An investor is considering a no-load mutual fund with an annual expense ratio of 0.4% and an annual 12b-1 fee of 0.55%. Another option is to invest a bank CD paying 5.5% per year. What minimum annual rate of return must the fund earn to make the investor better off in the fund than in the CD?

Answers

Answer:

6.45%

Explanation:

Calculation for the minimum annual rate of return that the fund must earn to make the investor better off in the fund than in the CD

Using this formula

Minimum annual rate=Bank CD+Annual expense ratio+Annual 12b-1 fee

Let plug in the formula

Minimum annual rate=5.5% per year + 0.4%+0.55

Minimum annual rate=6.45%

Therefore the minimum annual rate of return that the fund must earn to make the investor better off in the fund than in the CD Will be 6.45%

Compute the present value of a $3,500 deposit in year 1, and another $3,000 deposit at the end of year 3 if interest rates are 10 percent. (Do not round intermediate calculations and round your final answer to 2 decimal places.)

Answers

Answer:

The present value is $5,435.76

Explanation:

The computation of the present value is shown below:

= [Deposit made in year 1 ÷ (1 + rate of interest)^time period + [deposit made at the end of year 3 ÷ (1 + rate of interest)^time period

= [$3,500 ÷  (1 + 0.10)^1] + [$3,000 ÷ (1 + 0.10)^3]

= $3,181.82 + $2,253.94

= $5,435.76

Hence, the present value is $5,435.76

During the year, the company produced and sold 30,000 units of product at a selling price of $18.50 per unit. There was no beginning inventory of product at the beginning of the year. What is the contribution margin ratio for Blaine Corporation (round to 1 decimal)

Answers

Answer:  67.7%

Explanation:

Contribution Margin ratio = (Sales per units - Variable cost per unit) / Sales per unit

Variable cost per unit = (Manufacturing + Marketing + Administrative)/ Units sold

= (115,000 + 22,000 + 42,000) / 30,000

= $5.97

Contribution Margin ratio = ( 18.50 - 5.97)/ 18.50

Answers

Answer:

Average accounts receivables = Beginning account receivable + Ending account receivable / 2

= ($920,000 + $980,000)/2

= $950,000

Therefore,

Account receivable turnover = $7,600,000 / $950,000

= 8.0 times

c. How much higher (lower) would Casebolt Company's net income have been under the direct write-off method than under the allowance method

Answers

Answer: $9,375

Explanation:

Under the direct writeoff method, only the actual bad debts incurred will be taken out from the income for the year.

With the Allowance method however, the amount to be taken out will be the percentage expected to be uncollectible.

Under direct method, income would reduce by the actual bad debt of $30,000.

Under Allowance the income would be reduced by;

= ¾%  * 5,250,000

= $39,375‬

Income would be higher with Direct write-off by;

= 39,375‬ - 30,000

= $9,375

1. People who own more cars tend to live longer than people who own fewer cars. Why is this relationship not evidence that buying more cars increases life expectancy

Answers

Answer:

Car & Life Expectancy positive relationship is not evident, as its due to an interlinking lurking variable ie buyer's affluence.

Explanation:

More cars linked to higher life expectancy, positive correlation between these variables is a spurious correlation. Spurious relationship is a relationship between variables, that appears to be true, when it is actually false.

Given variables' correlation is spurious, as it is not logically correct (evident). It seems to be misleading correct because of a lurking variable, buyer's affluence. Lurking variable affects both independent (causal) & dependent (affected) variable, which creates a statistical illusion of variables' correlation.

In this case, affluence being lurking variable affects both number of cars owned & life expectancy. This seemingly creates a correlation between the non evidently linked variables as 'cars & life expectancy having positive relationship'

A Rose Is a Rose, but Only If It Is Fresh Supply chains for food and flowers must be fast, and they must be good. When the food supply chain has a problem, the best that can happen is the customer does not get fed on time; the worst that happens is the customer gets food poisoning and dies. In the floral industry, the timing and temperature are also critical. Indeed, flowers are the most perishable agricultural item—even more so than fish. Flowers not only need to move fast, but they must also be kept cool, at a constant temperature of 33 to 37 degrees. And they must be provided preservative-treated water while in transit. Roses are especially delicate, fragile, and perishable. Eighty percent of the roses sold in the U.S. market arrive by air from rural Colombia and Ecuador.

Peter forgot to file his tax return by April 15. He did not file an extension. Peter finally filed his tax return on July 31 and had a remaining tax liability of $3,500. What is Peter's failure to file penalty

Answers

Answer:

Peter's failure to file penalty = $700

Explanation:

Peter filed tax return on July 31 after forgetting to file his tax return by April 15 and did not ask for extension.  This means that the IRS can impose a 20% penalty on Peter for the tax due on a return where there is negligence, as can be established in this case.

Peter's remaining tax liability = $3,500

Penalty = $700 ($3,500 * 20%)

On your tenth birthday, you received $1,000 which you invested at 6.5% interest, compounded annually. Your investment is now worth $5,476. How old are you today

Answers

Answer:

Age= 37 years

Explanation:

Giving the following information:

Present value= $1,000

Future value= $5,476

Interest rate= 6.5%

First, we need to calculate the number of years passed using the following formula:

n= ln(FV/PV) / ln(1+i)

n= ln(5,476/1,000) / ln(1.065)

n= 27 years

Age= 10 + 27 = 37 years

Imagine a machine takes 50 minutes to complete one unit on a production line. Of the 50 minutes, 40 minutes was actual productive utilization. For 10 minutes the resource was idle, needing to pause and wait for other processes to finish during the production. What is the average labor utilization (round to the nearest %)

Answers

Answer:

80%

Explanation:

the average labor utilization rate is calculated by dividing total labor time applied by the addition of total labor time applied plus idle time. In this case, total labor time applied is 40 minutes and idle time is 10 minutes:

average labor utilization rate = 40 minutes / (40 + 10 minutes) = 40 / 50 = 0.8 = 80%

Three Corners Markets paid an annual dividend of $1.8 a share last month. Today, the company announced that future dividends will be increasing by 2.8 percent annually. If you require a return of 12.0 percent, how much are you willing to pay to purchase one share of this stock today

Answers

Answer:

$20.11

Explanation:

The computation of the price i.e. paid is shown below:

Given that

Growth rate = 2.8%

Dividend at time 0 = $1.8

So,  

Dividend at time 1 = Dividend at time 0 × (1 + growth rate)

= $1.8 × (1 + 2.8%)

= $!.85

And,  

Required return = 12%

Based on the above information

Now use the Gordon Growth formula,

Price today = Dividend at time 1  (Required return - Growth rate)

= $1.85 ÷ (12% - 2.8%)

= $20.11
