In a closed economy Keynesian Cross framework show how a decline in investment will lead to a fall in income. Explain the role of the consumption function and the multiplier in this process.

Sketch the closed loop frequency response M(jw) as a function of frequency for a unity feedback system with G(s)=10/s(s+2).

1. Explain what a closed-ended question is (provide an example) and tell me what its advantages and disadvantages are? (Be detailed and use your own verbiage.)

In 2019, NB Inc.’s federal taxable income was $246,000. Compute the required installment payments of 2020 tax in each of the following cases:

Required:

2. NB’s 2020 taxable income is $837,000.
3. NB’s 2020 taxable income is $1,390,000.

1. What is the unique procedure available to fund shareholders for challenging a fund adviser’s management fees as excessive? What factors do courts use in determining excessive fees?

2. What are the critical differences between mutual funds and closed-end funds? Why do you think closed-end funds have declined in popularity relative to mutual funds?

3. How are exchange-traded funds (ETFs) and unit investment trusts (UITs) different from index mutual funds, and from each other?

1. A given open loop room heating system has a gain of 1.2 and a time constant of 15 seconds. Derive the transfer function of the system in Laplace domain.

2. A closed loop proportional controller was implemented for the system described in Task 1 Q1 above to reduce the time constant to 10 seconds.

a. Draw the block diagram of the system, assuming that the error signal is the difference between the set and actual measured room temperatures.

b. Calculate the gain value (K) of the proportional control action that achieve the above response.

c. Derive the overall closed-loop transfer function in Laplace domain.

Company Inc owns a DC in Maryland with disruptions the year due to snowstorms. The number of disruptions follows a Poisson distribution with an average of 8.8 disruptions per year.

1. What is the probability that the number of disruptions next year at this DC is equal to or less than 4?

2. What is the probability of facing no disruptions at this DC during next year?

The time to recover from a disruption follows a uniform distribution with a minimum of 4 and a maximum of 13 days.

3. If a disruption happens, what is the average time the DC will be closed for?

4. If a disruption happens, what is the probability that the DC will be closed for more than 7 days?
