If the following times are estimated for an activity of the project, calculate the mean and the variance using PERT analysis.
a = 5
b = 13
m = 9

Answers

Answer 1

PERT (Program Evaluation and Review Technique) analysis is an approach used in project management to estimate project completion times based on three time estimates: optimistic (O), most likely (M), and pessimistic (P).

The mean and variance are used to determine the probability distribution for the completion time of a particular activity given these estimates.If the optimistic time (b) is 13 and the most likely time (m) is 9, we can calculate the pessimistic time (p) using the formula: p = (4m - b)/3p = (4 * 9 - 13)/3p = 7Therefore, the three time estimates for this activity are:b = 13m = 9p = 7The mean of these estimates can be calculated using the formula: mean = (b + 4m + p)/6mean = (13 + 4 * 9 + 7)/6mean = 10The variance can be calculated using the formula: variance = ((b - m)/6)^2 + ((p - m)/6)^2 + ((p - b)/6)^2variance = ((13 - 9)/6)^2 + ((7 - 9)/6)^2 + ((7 - 13)/6)^2variance = 1.67Therefore, the mean completion time for this activity is 10, and the variance is 1.67. These values can be used to estimate the probability distribution for the completion time of the activity and to make decisions about the project schedule and resources needed.

Peyton Manufacturing is trying to decide between two different conveyor belt systems. System A costs $280,000, has a four-year life, and requires $85,000 in pretax annual operating costs. System B costs $396,000, has a six-year life, and requires $79,000 in pretax annual operating costs. Both systems are to be depreciated straight-line to zero over their lives and will have zero salvage value. Suppose the company always needs a conveyor belt system; when one wears out, it must be replaced. Assume the tax rate is 25 percent and the discount rate is 9 percent. Calculate the EAC for both conveyor belt systems. (Your answers should be negative values and indicated by minus signs. Do not round intermediate calculations and round your answers to 2 decimal places, e.g., 32.16.)

Answers

The EAC is the annual cost that would be equivalent to the costs incurred over the life of the system. To calculate the EAC (Equivalent Annual Cost) for each conveyor belt system, we need to determine the annual cash flows for each system and then calculate the present value of those cash flows.

For System A:

Initial Cost: -$280,000

Annual Operating Costs: -$85,000

Annual Cash Flow: -$85,000 (Operating Costs)

Depreciation Expense: -$280,000 / 4 = -$70,000

To calculate the tax savings from depreciation, we multiply the depreciation expense by the tax rate:

Tax Savings: $70,000 * 0.25 = -$17,500

Net Cash Flow (Year 0): -$280,000

Net Cash Flow (Years 1-4): -$85,000 - $17,500 = -$102,500

For System B:

Initial Cost: -$396,000

Annual Operating Costs: -$79,000

Annual Cash Flow: -$79,000 (Operating Costs)

Depreciation Expense: -$396,000 / 6 = -$66,000

Tax Savings: $66,000 * 0.25 = -$16,500

Net Cash Flow (Year 0): -$396,000

Net Cash Flow (Years 1-6): -$79,000 - $16,500 = -$95,500

Next, we calculate the present value of the net cash flows for each system using the discount rate of 9%.

For System A:

EAC_A = PV of Net Cash Flows / PVIFA(9%, 4)

EAC_A = [(-$280,000) + (-$102,500) / 0.09] / [1 - (1 / (1 + 0.09)^4)]

EAC_A = (-$382,500 / 0.3053) = -$1,252,955.14

For System B:

EAC_B = PV of Net Cash Flows / PVIFA(9%, 6)

EAC_B = [(-$396,000) + (-$95,500) / 0.09] / [1 - (1 / (1 + 0.09)^6)]

EAC_B = (-$491,500 / 0.4024) = -$1,221,512.40

Therefore, the EAC for System A is -$1,252,955.14 and for System B is -$1,221,512.40.

Answers

The European Central Bank (ECB) adopted a negative interest rate policy to address the eurozone crisis. The ECB lowered its deposit rate to -0.1% that year to prevent deflation and bring the economic bloc out of a long-term recession.

In theory, negative interest rates would boost the economy by encouraging consumers and banks to take more risks through borrowing and lending money. Traditional monetary policy fails in the presence of zero lower bounds as the interest rates can't go lower. As a result, the central bank is unable to stimulate borrowing and lending in the economy.

When interest rates are already near zero, the effectiveness of monetary policy is severely restricted as it can no longer boost investment and consumption demand through interest rate cuts. Hence, conventional monetary policy becomes ineffective when interest rates hit zero and even quantitative easing (QE) has only limited effects. In this case, the negative interest rate policy may help the ECB bring the economy out of recession by lowering borrowing costs and increasing the availability of credit, thereby increasing investment and consumption.

The National Fire Protection Association has classified fires
according to three basic types. List them, including a brief
description of each.

Answers

The National Fire Protection Association has classified fires according to three basic types. These types of fire are based on the type of fuel that is burning.

The three basic types of fires are:Class A fire:This type of fire is the most common and occurs when materials like wood, paper, plastic, and cloth ignite. They are usually fueled by combustible solids. When these materials burn, they leave an ash residue. This fire can be extinguished with water, foam, or dry chemical.Class B fire:This type of fire is caused by flammable or combustible liquids such as gasoline, oil, and kerosene.

They can also involve flammable gases. Class B fires can spread quickly and can be challenging to put out because they can re-ignite. Water should not be used to put out a Class B fire because it can spread the fire. Class B fires are best extinguished using foam, dry chemical, or carbon dioxide.Class C fire:This type of fire is caused by electrical equipment, such as motors, transformers, and appliances. Because electricity is involved, it is essential to shut off the power source before attempting to put out the fire. Class C fires are often caused by a short circuit or overload. This type of fire can be extinguished by using a fire extinguisher with a non-conductive agent like carbon dioxide or a dry chemical.

what is the form of business ownership where you are taxed only at the personal level?

Answers

The form of business ownership where you are taxed only at the personal level is known as a "pass-through entity."

Pass-through entities are not subject to separate corporate taxation. Instead, the income or losses of the business "pass through" to the owners, who report them on their individual tax returns and are taxed at their personal tax rates. The owners of pass-through entities are typically responsible for paying self-employment taxes as well.

Examples of pass-through entities include sole proprietorships, partnerships, limited liability companies (LLCs), and S corporations. Each of these business structures has its own characteristics and legal requirements, so it's essential to consult with a qualified tax professional or attorney to determine the most suitable option for your specific circumstances.

Answers

The Target fixed assets/sales ratio of Earleton's is 23.58% . The required increase in fixed assets is $242,454,000.

If Earleton Manufacturing Company is currently operating at 85% of capacity and has $2 billion in sales, to determine the level of sales it could have obtained if operating at full capacity, we can use the formula:

Full capacity sales = Current sales / Capacity utilization

Full capacity sales = $2,000,000,000 / 0.85 = $2,352,941,176 (rounded to the nearest dollar).

To calculate Earleton's target fixed assets/sales ratio, we divide the fixed assets by the sales and multiply by 100:

Target fixed assets/sales ratio = (Fixed assets / Sales) * 100

Target fixed assets/sales ratio = ($471,500,000 / $2,000,000,000) * 100 = 23.58% (rounded to two decimal places).

If Earleton's sales increase by 20%, we need to calculate the increase in fixed assets required to maintain the target fixed assets/sales ratio. First, we determine the new sales level:

New sales = Current sales + (Current sales * Sales increase)

New sales = $2,000,000,000 + ($2,000,000,000 * 0.20) = $2,400,000,000

Then, we calculate the required increase in fixed assets:

Required increase in fixed assets = (New sales * Target fixed assets/sales ratio) - Current fixed assets

Required increase in fixed assets = ($2,400,000,000 * 0.2358) - $471,500,000 = $242,454,000 (rounded to the nearest dollar).
