a. 3.67; 1
b. 3.67; 6
c. 4.33; 1
d. 4.33; 6
e. none of these

Answers

Answer 1

If an activity on a PERT network has these time estimates: optimistic = 2, most likely = 3, and pessimistic = 8. Its expected time and variance are 4.33 and 1 respectively. So, option (c) is the correct answer.

The expected time for an activity in PERT is calculated as:

(optimistic + 4 × most likely + pessimistic) ÷ 6

So for this activity, the expected time is:

(2 + 4 × 3 + 8) ÷ 6 = 4

The variance for an activity in PERT is calculated as:

((pessimistic - optimistic) ÷ 6)²

So for this activity, the variance is:

((8 - 2) ÷ 6)² = 0.44

Therefore, the answer is 4.33; 1 (rounded to two decimal places).

TC = 235 + 41Q + 5Q2What is the average variable cost when 11 units are produced?Enter as a value.

Answers

To find the average variable cost when 11 units are produced for the given total cost (TC) function, TC = 235 + 41Q + 5Q^2, we'll follow these steps:

1. Identify the variable cost (VC) portion of the TC function: VC = 41Q + 5Q^2
2. Substitute the value of Q (number of units produced) with 11.
3. Calculate the VC when 11 units are produced.
4. Find the average variable cost (AVC) by dividing the VC by the number of units (Q).

Let's do the calculations:

1. VC = 41Q + 5Q^2
2. VC = 41(11) + 5(11^2)
3. VC = 451 + 5(121) = 451 + 605 = 1056
4. AVC = VC / Q = 1056 / 11 = 96

So, the average variable cost when 11 units are produced is 96. This means that, on average, it costs 96 units of currency to produce each unit of the product when 11 units are made.

The terms "average," "variable," and "value" are all involved in this calculation, as we determined the average (AVC) for the variable portion of the cost (VC) for a specific production value (Q = 11 units).

Question 2 (1 point)
The old Michigan football coach had only two strategies, Run the Ball to the Left Side of the line, and Run the Ball to the Right Side.
The defense can concentrate either on the left side or the right side of Michigan’s line.
If the opponent concentrates on the wrong side, Michigan is sure to gain at least 5 yards.
If the defense defended the left side and Michigan ran left, Michigan would be stopped for no gain.
But if the opponent defended the right side when Michigan ran right, Michigan would still gain at least 5 yards with probability .70.
It is the last play of the game and Michigan needs to gain 5 yards to win.
Both sides choose Nash equilibrium strategies.
In Nash equilibrium, Michigan would:
Question 2 options:
a. run to the right side with probability .77.
b. run to the right side with probability .50.
c. run to the right side with probability .70.
d. be sure to run to the right side.
e. run to the right side with probability .87.

Answers

The right answer is b. run to the right side with probability .50. To solve this problem, we need to find the Nash equilibrium strategies for both Michigan's offense and the defense.

Let p be the probability that Michigan runs to the right side, and q be the probability that the defense concentrates on the right side. We need to find the value of p that satisfies the conditions of a Nash equilibrium.

1. If the defense concentrates on the right side (q), Michigan's expected gain when running to the right is 0.7 * 5 = 3.5 yards, and when running to the left is 5 yards. To make the defense indifferent between left and right, we must have:

5(1 - q) = 3.5q
5 - 5q = 3.5q
5 = 8.5q
q ≈ 0.588

2. If Michigan runs to the right with probability p, the expected gain when the defense concentrates on the right is 3.5p and when they concentrate on the left is 5(1 - p). To make Michigan indifferent between running left and right, we must have:

3.5p = 5(1 - p)
3.5p = 5 - 5p
8.5p = 5
p ≈ 0.588

Thus, in Nash equilibrium, Michigan would run to the right side with probability approximately 0.588, which is not among the given options. However, option b (probability .50) is the closest choice to the calculated probability, so the answer would be: run to the right side with probability .50.

https://brainly.com/question/12248636#SPJ1

Understanding the Federal Reserve's impact on bank lending involves examining the discount rate, reserve ratio, and the Fed's transactions involving Treasury bonds. Let's break it down.

Short Answer:

The Fed lowers the discount rate from 4 percent to 2 percent.The Fed buys $400 million worth of Treasury bonds from commercial banks.

Explanation:

The Federal Reserve, or the Fed, uses a couple of key tools to manage the economy, the discount rate and the reserve ratio. These are like the dials on your gaming console, with the Fed tweaking them to control how much money banks have to lend. Here's how these tools work:

Discount Rate: This is the interest rate the Fed charges banks to borrow money. When the Fed lowers this rate, like from 4% to 2%, it's like a massive sale in your favorite game store – borrowing gets cheaper for the banks. So they borrow more, which increases their reserves, and that means they've got more money to lend out to folks like us. This action increases bank lending.Treasury Bonds: These are kind of like IOUs that the government issues when it needs money. When the Fed buys these bonds from banks, like $400 million worth, it’s like they've just scored big. With this cash, the banks' reserves go up, which means they can lend out more money.

Summary:

So, to put it simply, the actions that increase bank lending are lowering the discount rate and buying Treasury bonds from banks. This is because these actions boost the banks' reserves, giving them more cash to lend. Think of it like having more ammo in a FPS game – the more you have, the more shots you can fire!

But if the Fed raises the discount rate or the reserve ratio, that would actually decrease lending. It's like the game suddenly getting harder and forcing you to conserve ammo. The banks need to keep more money in their vaults, so they have less to lend out. Just remember, it's all a big balancing act!

Answers

The value of Stone Soups, an unlevered company with an after-tax net income of $228,400, is $1,270,676. After-tax net income is the income left over after taxes have been deducted from gross income for a business or individual.

To calculate the value of Stone Soups, we need to use the formula for the unlevered cost of capital, which is:
Unlevered Cost of Capital = Cost of Equity x (Equity / (Equity + Debt))

We know that the unlevered cost of capital is 14.2 percent, and that the company is unlevered, which means it has no debt. Therefore, the Equity / (Equity + Debt) ratio is 1, and the cost of equity can be calculated as:

Cost of Equity = Unlevered Cost of Capital / (1 - Tax Rate)
Cost of Equity = 14.2% / (1 - 21%)
Cost of Equity = 17.98%

Next, we can use the formula for the value of the company, which is:
Value of the Company = After-tax Net Income / Cost of Equity

Plugging in the numbers, we get:
Value of the Company = $228,400 / 17.98%
Value of the Company = $1,270,676

Therefore, the answer is option (a) $1,270,676. This means that the value of Stone Soups, an unlevered company with an after-tax net income of $228,400, is $1,270,676.

Hitec Home Services manufactures a ventilation controller designed for monitoring and controlling carbon monoxide in parking garages, boiler rooms, tunnels, etc. The net cash flows associated with one phase of the operation are shown below.
1. How many possible rate of return values are there for this cash flow series?
2. Find all the rate of return values between 0 and 100% using tabulated factors and a spreadsheet.
3. (Added spreadsheet exercise) Resolve to find any values between −99% and 0%. Does the result agree with the conclusion of the rule of signs (Descartes’ rule) and cumulative cash flow (Norstrom’s criterion) tests?

Answers

Net cash flow is the difference between the total cash inflows and the total cash outflows of a business or investment project over a specific period.

1. The number of possible rate of return values for a cash flow series is determined by the number of sign changes in the net cash flows. Since the question does not provide the actual cash flow data, I cannot determine the exact number of sign changes. However, you can find this by analyzing the cash flow series and counting the number of times the cash flow changes from positive to negative or vice versa.

2. To find all the rate of return values between 0 and 100% using tabulated factors and a spreadsheet, you can apply the Internal Rate of Return (IRR) function. In Excel, you can use the "IRR" function with the cash flow series as input. Iterate through different rates (0 to 100%) to find any possible IRR values within this range.

3. To find values between -99% and 0%, you can follow the same approach as mentioned in point 2, but with the range from -99% to 0% instead.

The rule of signs (Descartes' rule) states that the number of positive real roots is either equal to the number of sign changes or less than that by an even number.

Norstrom's criterion states that if the cumulative cash flow is always positive or zero, then there is only one real IRR. Comparing the results from the spreadsheet exercise to these rules can help you verify if they agree with the conclusions of these tests.

which of the following is true of a firm?multiple choice question.its decisions regarding what output level to produce are typically marginal decisions.it should avoid taking into account opportunity costs when making business decisions.it should consider sunk costs when making business decisions.its decisions regarding what output level to produce are typically based on total revenue and total cost data.

Answers

Out of the given options, the statement that is true of a firm is that "its decisions regarding what output level to produce are typically based on total revenue and total cost data." Option A

This means that a firm considers both its total revenue and total cost when deciding on the output level to produce. By doing so, it can ensure that it produces enough output to generate maximum revenue while keeping its costs under control.
It is important for a firm to consider opportunity costs when making business decisions. Opportunity cost is the cost of an alternative that must be forgone to pursue a certain action. By considering opportunity costs, a firm can ensure that it makes the most profitable decision.
Similarly, sunk costs should not be considered when making business decisions. Sunk costs are the costs that have already been incurred and cannot be recovered. Since sunk costs are irretrievable, they should not be taken into account when making future business decisions.
In conclusion, a firm's decision regarding what output level to produce is typically based on total revenue and total cost data. However, it is important for a firm to consider opportunity costs and avoid taking sunk costs into account when making business decisions. Therefore Option A is correct.

which of the following is true? a. competitive forces are present even in markets with high barriers to entry. b. quality competition is an unimportant element of the competitive process. c. profitability and high prices discourage technological change and the development of substitute products. d. government regulations have substantially increased the quality of american manufacturing products in recent years.

Answers

The true statement among the given options is competitive forces are present even in markets with high barriers to entry. Option A

This statement implies that although there may be barriers to entry in certain markets, such as patents, economies of scale, or government regulations, competition still exists. Existing firms compete against each other through price, product differentiation, marketing, and other strategies. Furthermore, the threat of potential new entrants can also stimulate competition and innovation among existing firms.

Option (b) is false since quality competition is a crucial element of the competitive process. Quality helps firms to differentiate their products from those of their competitors, and it can also increase customer satisfaction and loyalty. Quality competition also promotes innovation and improvement in product design and features, which can lead to higher profitability.
Option (c) is also false since profitability and high prices can incentivize firms to invest in technological change and product development. Higher prices can generate profits that can be reinvested in research and development, leading to the creation of new products and technologies. In addition, high prices can attract new entrants to the market, which can increase competition and innovation.
Option (d) is also false since there is no evidence to suggest that government regulations have substantially increased the quality of American manufacturing products in recent years. While regulations can help to ensure minimum standards of quality and safety, they can also impose costs and reduce flexibility for firms. Quality improvement and innovation are primarily driven by market forces, such as competition and customer demand.
In summary, the true statement is that competitive forces are present even in markets with high barriers to entry, and quality competition is an important element of the competitive process. Profitability and high prices can incentivize innovation and product development, while government regulations may have limited impact on the quality of manufacturing products. Option A is correct.

assuming the market is arbitrage-free, if a six-month pure discount bond yields 1.9%, a one-year pure discount bond yields 2.3%, an eighteen- month pure discount bond yields 2.65%, and a two-year discount bond yields 3.05%, what should be the price of a two-year $1,000 6% par-value bond with semiannual coupons?

Answers

To determine the price of the two-year $1,000 6% par-value bond with semiannual coupons, we need to calculate the present value of the future cash flows, which includes the semiannual coupon payments and the final payment of the par value.


First, we need to calculate the semiannual coupon payment, which is $1,000 x 6% / 2 = $30.

Next, we need to calculate the number of semiannual periods in two years, which is 4.

Using the yields given for the pure discount bonds, we can calculate the discount factors for each period as follows:

- 6-month: 1 / (1 + 1.9% / 2) = 0.990277
- 1-year: 1 / (1 + 2.3% / 2) ^ 2 = 0.972443
- 18-month: 1 / (1 + 2.65% / 2) ^ 3 = 0.954874
- 2-year: 1 / (1 + 3.05% / 2) ^ 4 = 0.938876

Using these discount factors, we can calculate the present value of the semiannual coupon payments and the final payment of the par value as follows:

- Coupon payments: $30 x (0.990277 + 0.990277^2 + 0.990277^3 + 0.990277^4 + 0.990277^5 + 0.990277^6) = $173.36
- Par value: $1,000 x 0.938876^8 = $776.02

Finally, we add the present value of the coupon payments and the final payment of the par value to get the price of the bond:

Price = $173.36 + $776.02 = $949.38

Therefore, assuming the market is arbitrage-free, the price of the two-year $1,000 6% par-value bond with semiannual coupons should be $949.38.

an example of an internal control weakness is to assign the payroll department the responsibility for:multiple choicepreparing the payroll expense distribution.preparing the payroll checks.authorizing increases in pay.preparing journal entries for payroll expense.

Answers

An internal control weakness is a flaw in the system that can lead to errors, fraud, or financial losses. One example of such a weakness is assigning the payroll department the responsibility of preparing journal entries for payroll expense. This can be problematic for several reasons.

Firstly, preparing journal entries requires a certain level of accounting knowledge and expertise. If the payroll department lacks this knowledge, they may make errors in the journal entries that could lead to inaccurate financial statements. Furthermore, if the department is overburdened with other responsibilities, they may rush through the journal entries and make mistakes that could go unnoticed.

Secondly, having the same department responsible for both preparing payroll checks and journal entries creates a lack of separation of duties. This means that the same person who is responsible for preparing payroll checks may also be responsible for recording those payments in the accounting system.

This opens up the possibility of fraud or embezzlement, as the person responsible for recording the payments could potentially manipulate the system to cover up any wrongdoing.In conclusion, assigning the payroll department the responsibility of preparing journal entries for payroll expense is an internal control weakness that could lead to errors, inaccuracies, and potential fraud.

To mitigate this weakness, it is important to have a separate department or individual responsible for preparing journal entries and ensuring that there is a clear separation of duties within the payroll department.
