An undergraduate business student has purchased a laptop computer for use during exams. This laptop is perfectly reliable except

for two parts: its microchip, which has a failure rate of one in every twenty hours of operation; and its battery, which has a failure rate of one in every ten hours of operation. Also, on average the battery will wear out in five hours, with a standard deviation of 30 minutes. Assuming that a new battery has just been installed, what is the probability that the laptop will perform reliably during a one-hour exam?

Answer:

probability of a reliable performance = 19/20

Explanation:

If a new battery has just been installed, then the chances of failure are only contributed by the faulty microchip, which has a failure rate of 1 in 20 hours.

Therefore in 1 hour, the probability that the laptop will perform reliably is calculated as follows:

Chances of failure = 1 in 20

20 hours = 1 chance of failure

∴ 1 hour = 1/20 chance of failure

1/20 = 0.05 chance of failure

Now, let us express 0.05 as fraction:

0.05 = 5/100

Therefore in 1 hour, there is a 5 in 100 chances of failure.

But we are asked to find the probability that the laptop will perform reliably. This is simply done by finding the difference between the total chances of occurrence (100)  and the chances of failure (5)

∴ Probability of reliable performance in one hour = (100 - 5) / 100

= 95/100

95/100 = 19/20

Current Assets=$193,000

Current Liabilities=$137,000

Cash=$62,000

Accounts receivable=$43,000

Inventory=$88,000

When it comes to executing plans, what is the role of a manager?
tiny-mole [99]

When it comes to executing plans, the role of a manager is controlling and problem solving.

<h3>Who is a manager?</h3>

Managers supervise the activities of others in order to achieve goals. Managers in the modern workforce may be in charge of systems or specific functions that do not involve humans.

A manager has several responsibilities in an organization. One of them is concerned with carrying out the plan devised to achieve organizational objectives. A manager uses this plan to control and solve problems that may arise while carrying out the plan, as well as to make necessary adjustments.

For example, compare actual results to planned results and make adjustments as needed.

elena55 [62]

Answer:

Part 1. Calculate the total prime cost for last week

Direct materials                    28,000

<u><em>Add </em></u>Direct labor                   28,000

Prime Cost                             56,000

Part 2. Calculate the per-unit prime cost

per-unit prime cost=$56,000/5,600

                                 =$10.00

Part 3. Calculate the total conversion cost for last week

Direct labor                                 28,000

<u>Add </u>Manufacturing Overheads 55,000

Total conversion cost                83,000

Part 4. Calculate the per-unit conversion cost.

per-unit conversion cost=$83,000/5,600

                                         =$14.82

Explanation:

Part 1. Calculate the total prime cost for last week

Prime Cost = Direct Materials + Direct Labor

Part 2. Calculate the per-unit prime cost

Per Unit Prime Cost = total prime cost/number of units manufactured

Part 3. Calculate the total conversion cost for last week

Conversion Cost = Direct Labor + Manufacturing Overheads

Part 4. Calculate the per-unit conversion cost.

Per-unit conversion cost =Total Conversion Cost / number of units manufactured

The world-famous discounter, Fernwood Booksellers, specializes in selling paperbacks for $7 each. The variable cost per book is
Ghella [55]

Answer:

Advertising= $933,333

Explanation:

Giving the following information:

The world-famous discounter, Fernwood Booksellers, specializes in selling paperbacks for $7 each. The variable cost per book is $5. At current annual sales of 200,000 books, the publisher is just breaking even. It is estimated that if the authors' royalties are reduced, the variable cost per book will drop by $1.

First, we need to calculate the fixed costs:

Break-even point (units)= fixed costs/ contribution margin

200,000=  fixed costs/ (7 - 5)

200,000= fixed costs/ 2

fixed costs= $400,000

Now, we need to calculate the new break-even point in dollars and units:

Break-even point (dollars)= fixed costs/ contribution margin ratio

Break-even point (dollars)= 400,000 / (6/7)= $466,666.67

Break-even point (units)= fixed costs/ contribution margin

Break-even point (units)= 400,000/6= 66,667 books

Total cost= 400,000 + $66,667= $466,667

Current income= 200,000*7= $1,400,000

Advertising= 1,400,000 - 466,667= $933,333
