(e) (10 pts) What is the requirement on the region of convergence (ROC) of a system function H(z) for a discrete-time LTI system to be causal? Is the system causal? Why? (f) (5 pts) is the system impulse response h[n] right-sided, left-sided or two-sided? Why?

Answers

Answer 1

The problem involves a discrete-time LTI (Linear Time-Invariant) system described by a difference equation. The task is to determine the z-transform of the difference equation, derive the system function, analyze the pole-zero plot and region of convergence, and discuss the stability and causality of the system. Finally, the problem asks to classify the impulse response as right-sided, left-sided, or two-sided.

(a) Taking the z-transform on both sides of the difference equation yields the transformed equation in terms of X(z) and Y(z).

(b) The system function H(z) is determined by rearranging the transformed equation to express Y(z) in terms of X(z) and then taking the ratio of Y(z) to X(z).

(c) If the discrete-time Fourier transform of the impulse response h[n] exists, the pole-zero plot of H(z) can be sketched. The region of convergence (ROC) is shaded to specify the range of z-values for which the z-transform converges.

(d) For a discrete-time LTI system to be stable, the ROC of H(z) must include the unit circle in the z-plane. By analyzing the ROC, the stability of the system can be determined.

(e) For a discrete-time LTI system to be causal, the ROC of H(z) must include the region outside a circle with a radius greater than the magnitude of the outermost pole. By examining the ROC, the causality of the system can be determined.

(f) The classification of the impulse response h[n] as right-sided, left-sided, or two-sided depends on the ROC of H(z). The ROC determines the range of values for which h[n] is nonzero, and thus the sidedness of the impulse response.

in an inflationary economic environment the selling price set for a firm's products will

Answers

In an inflationary economic environment, the selling price set for a firm's products will typically increase over time.

This is because inflation causes the general level of prices in the economy to rise, making it more expensive for firms to produce their products and services.

To maintain their profit margins, firms will need to pass on these higher production costs to their customers by raising their prices.

However, the extent to which a firm can raise its prices will depend on various factors, such as the level of competition in the market and the elasticity of demand for its products.

So, in short, the selling price set for a firm's products in an inflationary economic environment will likely go up, but the specific amount will depend on a range of different factors.

Answers

When we use the term "true," we refer to a claim that accurately captures reality or complies with verifiable facts. When we claim something is false, we mean it doesn't accurately reflect reality or isn't backed up by facts.

1. True. A unit of account is a function of money that allows for measuring and comparing the value of goods and services. In order to do so, money must be divisible into smaller units. For example, the US dollar can be divided into cents.

2. True. Dollarization occurs when a country adopts the US dollar as its official currency or when it decides to tie its monetary policy to the US dollar. This can happen for various reasons, such as to stabilize inflation or to increase confidence in the local currency.

3. True. Many countries did abandon silver as a backer of their currency after the Great Depression. This was because they wanted to increase their money supplies and couldn't do so while being tied to a finite amount of silver reserves. Instead, many countries shifted to fiat currencies, which are not backed by any physical commodity.

4. False. The US money supply has actually increased dramatically in response to the pandemic, as the Federal Reserve has implemented various measures to stimulate the economy and prevent a financial crisis. These measures include lowering interest rates, increasing asset purchases, and providing liquidity to financial markets. The concern is not inflationary pressures, but rather deflationary pressures due to the economic downturn caused by the pandemic.

Let's assume that one knows for sure that the stock price will increase by 10% or decrease by 10% over the next year. Unfortunately, no put options are traded on Picard Enterprise. What portfolio position in stock and T-bills will ensure you a payoff equal to the payoff that would be provided by a protective put portfolio (stock plus put with strike X = $50)?

a.1 share of stock and equal to the present value of 25 a year from now

b.½ share of stock and $25 in bills

c.1 share of stock and $50 in bills

d. ½ share of stock and bills equal to the present value of 27.5 a year from now

Answers

The  ½ share of stock and bills equal to the present value of 27.5 a year from now. The correct option is d.

Since no put options are available for Picard Enterprise, we need to create a portfolio that replicates the protective put position. A protective put position involves buying one share of stock and a put option with a strike price of $50. The put option would guarantee a minimum value of $50 at year-end, but since no put options are available, we need to create a similar payoff using stock and T-bills.

To replicate the protective put position, we can buy ½ share of stock and invest the remaining money in T-bills. If the stock price increases by 10% to $55, our ½ share of stock will be worth $27.5. If the stock price decreases by 10% to $45, our ½ share of stock will be worth $22.5. In either scenario, we can add the present value of $27.5 at year-end to our portfolio to ensure a minimum payoff of $50.

Therefore, the correct portfolio position is d. ½ share of stock and bills equal to the present value of 27.5 a year from now.

a single-period inventory problem can be solved using a technique called:_____.

Answers

A single-period inventory problem can be solved using a technique called "Newsvendor Model"

The Newsvendor Model is a widely used technique for solving single-period inventory problems. It is often applied in situations where a business needs to determine the optimal quantity of a product to order or produce for a specific time period, considering uncertain demand and cost factors.

In the Newsvendor Model, the decision-maker aims to balance the trade-off between stocking enough inventory to meet potential customer demand and avoiding excess inventory that would lead to waste or additional costs. The objective is to maximize expected profit or minimize expected costs by finding the optimal order quantity.

The model incorporates factors such as the selling price, cost of goods, salvage value of unsold inventory, and the probability distribution of demand. By analyzing these variables, the Newsvendor Model provides insights into the optimal stocking decision, which minimizes the expected cost of understocking or overstocking.

The technique takes its name from the analogy of a newspaper vendor who must decide how many newspapers to purchase for a day, as any unsold newspapers cannot be sold the next day. By applying mathematical methods and probability theory, the Newsvendor Model helps businesses make informed decisions regarding their inventory levels in single-period scenarios.

When doing blood testing for a viral infection, the procedure can be made more efficient and less expensive by combining partial samples of different blood specimens. If samples from three people are combined and the mixture tests negative, we know that all three individual samples are negative. Find the probability of a positive result for three samples combined into one mixture, assuming the probability of an individual blood sample testing positive for the virus is 0.11. Probability = _____ (Round to four decimal places)

Answers

Probability of a positive result is 0.295031.

To calculate the probability of a positive result for three samples combined into one mixture, we can use the concept of the complement rule.

The complement rule states that the probability of an event A occurring is equal to 1 minus the probability of the event A not occurring.

In this case, the probability of an individual blood sample testing positive for the virus is given as 0.11. Therefore, the probability of an individual blood sample testing negative is 1 - 0.11 = 0.89.

Since the samples from three people are combined into one mixture, we want to find the probability that all three individual samples test negative in the mixture. As the samples are combined, the probability of each individual sample testing negative is multiplied together.

Therefore, the probability of all three samples testing negative in the mixture is 0.89 * 0.89 * 0.89 = 0.704969.

Finally, to find the probability of a positive result for the three samples combined into one mixture, we subtract the probability of all three samples testing negative from 1:

Probability of a positive result = 1 - 0.704969 = 0.295031.

Rounding to four decimal places, the probability of a positive result for the three samples combined into one mixture is approximately 0.2950.

how many 50-foot by 110-foot lots could be obtained from an acre of land?

Answers

An acre of land is equivalent to 43,560 square feet. To determine how many 50-foot by 110-foot lots can be obtained from an acre, you need to calculate the size of one lot and then divide the area of an acre by that number.
To determine the number of 50-foot by 110-foot lots that can be obtained from an acre of land, we first need to calculate the total area of the land in square feet.

An acre is equal to 43,560 square feet.

Next, we calculate the area of each lot:

50 feet (width) * 110 feet (length) = 5,500 square feet

Now, we divide the total area of the land by the area of each lot to find the number of lots:

43,560 square feet / 5,500 square feet = 7.92 lots

Since we cannot have a fractional number of lots, we round down to the nearest whole number.

Which of the following costs probably should not be allocated to the investment needed for a new project?
A. Increase in accounts receivable
B. New warehouse, built for this project
C. 25 percent of the vice president's salary
D. Labour expense for employees in new warehouse

Answers

The cost that probably should not be allocated to the investment needed for a new project is option C, 25 percent of the vice president's salary.

When allocating costs to a new project, it is essential to include only those costs directly related to the project and contribute to its successful implementation. Costs that do not have a direct impact on the project should be excluded from the allocation.

Option A, the increase in accounts receivable, can be considered as a relevant cost to the project as it reflects the impact on cash flow and working capital requirements.

Option B, the new warehouse built for the project, is directly tied to the project's infrastructure and would be a necessary investment.

Option D, the labor expense for employees in the new warehouse, is a direct cost associated with the operation of the project and should be allocated.

However, option C, 25 percent of the vice president's salary, is not directly tied to the new project. Unless the vice president's role specifically relates to the project and their time and effort are dedicated solely to its management and execution, it should not be allocated as a cost of the new project. Allocating a portion of the vice president's salary would inaccurately inflate the project's costs and may not accurately reflect the resources utilized for its implementation.

Therefore, option C, 25 percent of the vice president's salary, is the cost that probably should not be allocated to the investment needed for the new project.

In the context of the importance of discipline, which of the following should be avoided because it makes it difficult for employees to understand what behavior is appropriate and what is not allowed?Multiple ChoiceInconsistencyRigidityConfrontationPermissiveness

Answers

Permissiveness should be avoided because it makes it difficult for employees to understand what behavior is appropriate and what is not allowed.

In a disciplinary context, permissiveness refers to a lack of clear boundaries or leniency in enforcing rules and standards. When there is a culture of permissiveness, employees may be uncertain about what actions are acceptable and what will be considered misconduct. This ambiguity can lead to confusion, inconsistency, and potential conflict among employees. Without clear guidelines, employees may engage in behaviors that undermine productivity, teamwork, and organizational values. On the other hand, a well-defined and communicated disciplinary framework provides employees with a clear understanding of expected behavior, consequences for misconduct, and the overall boundaries within which they should operate. It helps create a positive work environment where employees can perform their roles effectively and contribute to the organization's success.

which one of the following statements best describes the actions of the smoothing constant as it moves closer to the smoothing constant α?

Answers

The smoothing constant, also known as α, is a critical parameter in time series forecasting. It is used to control the weight assigned to the most recent observation when calculating the forecast for the next period.

When the smoothing constant moves closer to α, the effect is that the forecast becomes more responsive to the most recent data. This is because the weight assigned to the most recent observation increases, and the weight assigned to the historical data decreases.

The smoothing constant is used in exponential smoothing, a technique used to forecast time series data. This technique assumes that the future values of a variable are a weighted average of past observations. The exponential smoothing model works by assigning exponentially decreasing weights to past observations, with the most recent observations being assigned the highest weight.

In general, the smoothing constant plays a crucial role in the accuracy of the forecast. If the smoothing constant is too low, the model may be too slow to respond to changes in the data, resulting in inaccurate forecasts.

Therefore, it is essential to find the optimal value for the smoothing constant that balances responsiveness and stability. In conclusion, as the smoothing constant moves closer to α, the forecast becomes more responsive to the most recent data, but finding the optimal value is critical for the accuracy of the forecast.

.A government will have an overall deficit that is smaller than its primary deficit if...

Answers

A government will have an overall deficit that is smaller than its primary deficit if it receives enough revenue from sources other than borrowing to cover its interest payments on its debt.

The primary deficit is the difference between the government’s total spending and its revenue, excluding interest payments on its debt. In contrast, the overall deficit includes interest payments on the government’s debt.

If a government is able to generate enough revenue from sources other than borrowing to cover its interest payments on its debt, it can prevent the growth of its overall deficit even if it continues to have a primary deficit. This is because interest payments on the government’s debt will not add to the overall deficit if they are covered by non-borrowed revenue.

This can be achieved by a number of means, including increasing tax revenue, reducing spending on non-essential programs, and expanding economic growth to generate more revenue. Governments can also reduce their overall deficit by refinancing their debt at lower interest rates or by restructuring their debt to reduce the amount of interest payments they need to make.

In summary, a government can reduce its overall deficit compared to its primary deficit by generating enough non-borrowed revenue to cover its interest payments on its debt. This requires a combination of increased revenue, reduced spending, and effective debt management strategies.

Suppose that 27% of students have their own Amazon account, 14% have their own Disney+ account, and 4% have both their own Amazon and Disney+ accounts. Let event A={a student has their own Amazon account} Let event D={a student has their own Disney+ account} Are events A and D mutually exclusive? Why or why not?

Answers

Events A and D are not mutually exclusive because there are students who have both their own Amazon and Disney+ accounts.

Mutually exclusive events refer to events that cannot occur at the same time. In this scenario, events A and D are not mutually exclusive because there are students who have both their own Amazon and Disney+ accounts. The information provided states that 27% of students have their own Amazon account, 14% have their own Disney+ account, and 4% have both accounts.

Since there is a non-zero percentage of students who fall into the intersection of having both accounts, it means that the events A and D can occur simultaneously. Therefore, events A and D are not mutually exclusive. Students can belong to both groups, indicating that having an Amazon account and having a Disney+ account are not mutually exclusive events in this context.
