Similar conditions as in previous question. A simple 3-phase power system includes generator G, step-up transformer TX1, transmission line TL, step-down transformer TX2 and load L. All elements are rated for S = 50 MVA (3 phase).

G: series impedance 0, rated voltage 600 V (line-to-line)

TX1: series impedance Z_TX1, voltage ratio 600 V : 100 kV (line-to-line)

TL: series impedance Z_TL;

TX2: series impedance Z_TX2; voltage ratio 100 kV : 1kV (line-to-line)

L: impedance Z_L.

Per unit system is based on  S = 50 MVA and the first base voltage V_baseG = 600 V (line-to-line) at the generator. In per unit system representation, current through the entire system equals 0.32 + j0.58 per unit.

Determine current (magnitude only) in the transmission line (TL) in Amps. Express your answer as a number with one digit after decimal point (as in 123.4)

Marcia Miller died July 23, 2017. Marcia (born April 2, 1930) resided at 117 Brandywine Way, Eastern City, PA 19000 and was a lifelong Pennsylvania resident. Her first husband, Arthur Adams, died in 1999. In June 1999, she married Matt Miller, a U.S. citizen, who survived her. Marcia has three children (Andy, Annie, and Archie Adams) from her first marriage.

Date of death values of the properties discovered at Marcia’s death are listed below.

Principal residence with a value of $420,000. Purchased by Marcia in 2001 and titles in the names of Matt and Marcia Miller, joint tenants with right of survivorship.

Household furnishings acquired by Marcia during her first marriage and values at $62,000 when she died.

$1 million cash in money market account in Marcia’s name. On her date of death, there also was $2,200 of accrued interest in the account.

$17,000 checking account at Keystone State Bank in the names of Marcia and Matt as tenants in common.

Stock portfolio in Marcia’s name with fair market value at her death of $5.6 million.

$1 million like insurance policy. Marcia purchased the policy in 1990 and held incidents of ownership. Beneficiary is Marcia’s estate, and Marcia held incidents of ownership.

Trust at Quaker State Bank with value of $500,000. The trust was created under the will of Marcia’s uncle, Josh Judson, who died in 1992. Marcia was entitled to receive all the income annually for life and was granted the power to will the property to such of her descendants as she so desired with the specification that, if she did not exercise the power, the property would pass to Josh’s Former housekeeper, Yvonne Jones.

Marcia’s will includes the following provisions:

I bequeath to Matt all of my tangible, personal property.

To First Lutheran Church I leave $50,000.

To a trust with PHL Bank I leave $200,000. Matt is to receive all the trust income quarterly for life, and the remainder is to be divided equally at his death among my three children or their estates.

I leave my sister Annette $100,000, but if she disclaims this amount, it will go to my beloved Matthew.

I appointed the property on the trust at Quaker State Bank to Annie Adams.

The rest of my property I leave to Andy (my first born).

Other pertinent information follows:

As of her date of death, Marcia owed her country club $800.

The cost of Marcia’s funeral and tombstone totaled $15,000.

Her accountant’s, attorney’s, and executor’s fees are estimated to be $120,000.

Annette made a qualified disclaimer of the $100,000 bequest.

Marcia’s executor, Susan, will make whatever elections will result in the lower tax payable. During her life, Marcia never made any taxable gifts and never consented to gift splitting.

Assume that, under state law, taxes and nay other costs associated with death are payable from the estate’s residue and that the state death tax owed is equal to the state death tax credit available on the federal estate tax return.

Prepare an estate tax return (Form 706) for Marcia. You will also need to prepare the following sub-schedules for Marcia:

B, C, D, E, F, J, K, M, O (These forms all need to be downloaded from the IRS website and the numbers must be manually loaded into the forms and then printed).

Mary Higgins is a freelance writer with enough spare time on her hands to play the stock market fairly seriously. Each morning she observes the change in stock price of a particular stock and decides whether to buy or sell, and if so, how many shares to buy or sell. Assume that on day 1, she has $100,000 cash to invest and that she spends part of this to buy her first 500 shares of the stock at the current price of $50 per share. From that point on, she follows a fairly simple “buy low, sell high” strategy. Specifically, if the price has increased three days in a row, she sells 25% of her shares of the stock. If the price has increased two days in a row (but not three), she sells 10% of her shares. In the other direction, if the price has decreased three days in a row, she buys up to 25% more shares, whereas if the price has decreased only two days in a row, she buys up to 10% more shares. The reason for the “up to” proviso is that she cannot buy more than she has cash to pay for. Assume a fairly simple model of stock price changes, as described in the file P16_51.xlsx. Each day the price can change by as much as $2 in either direction, and the probabilities depend on the previous price change: decrease, increase, or no change. Build a simulation model of this strategy for a period of 75 trading days. (You can assume that the stock price on each of the previous two days was $49.) Choose interesting @RISK output cells, and then run @RISK for at least 1000 iterations and report your findings. - please how to use R to resolve? Thanks.

Black Box Cable TV is able to purchase an exclusive right to sell a premium movie channel (PMC) in its market area. Let's assume that Black Box Cable pays $150,000 a year for the exclusive marketing rights to PMC. Since Black Box has already installed cable to all of the homes in its market area, the marginal cost of delivering PMC to subscribers is zero. The manager of Black Box needs to know what price to charge for the PMC service to maximize her profit. Before setting price, she hires an economist to estimate demand for the PMC service. The economist discovers that there are two types of subscribers who value premium movie channels. First are the 4,000 die-hard TV viewers who will pay as much as $150 a year for the new PMC premium channel. Second, the PMC channel will appeal to 20,000 occasional TV viewers who will pay as much as $20 a year for a subscription to PMC.

If Black Box Cable TV is unable to price discriminate, what price will it choose to maximize its profit, and what is the amount of the profit?
a. price = $20; profit = $400,000
b. price = $20; profit = $330,000
c. price = $150; profit = $450,000
d. price = $150; profit = $600,000

If Black Box Cable TV is able to price discriminate, what would be the maximum amount of profit it could generate?
a. $500,000
b. $600,000
c. $850,000
d. $925,000

What is the deadweight loss associated with the non-discriminating pricing policy compared to the price discriminating policy?
a. $375,000
b. $400,000
c. $475,000
d. It cannot be determined from the information provided.

Write a program, called NationalTax, that will simulate calculating a citizen's income tax for the year.

A country uses lettered ID's to identify its citizens. Valid ID's will be either 8 or 9 characters long. All characters entered will be alphabetic characters only (a-z or A-Z).

• Display a welcome message.
• Prompt the user for their ID and read it in.
• Next, determine if the ID is valid based on its length.
  • If it is not valid, simply state that the ID is invalid and let the program end naturally (you may NOT use System.exit).
  • However, if it is valid, then do the following:
    • Prompt the user for the tax year (entered as a four-digit integer). No validity check needs to happen here.
    • Prompt the user for their annual income (this includes dollars and cents) and read it in. Since no annual income can be less than zero, if the user enters a negative amount, simply convert it to its positive amount. You may not use if/else statements here. Use the appropriate Math library method.
    • Convert the ID to all CAPS.
    • Display the ID.
    • Display the annual income as dollars and cents.
    • Set the tax amount to be log₁₀ of their annual income multiplied by 100. Display this as their initial tax amount.
    • Then if the first character of the ID is in the range:
      • A - G, then the person works for the government. Reduce their tax by 10%. Display that they are a government employee, that they receive a 10% tax reduction, and display the new tax amount.
      • H - P, then the person works in the public sector. There is no tax reduction. Display they they are a public sector employee and that they receive no tax reduction.
      • Q - U, then the person is unemployed. Display that they are unemployed and that they receive no tax reduction.
      • Otherwise the person is retired. Reduce their tax by 25%. Display that they are retired, that they receive a 25% tax reduction, and display the new tax amount.
    • Then if the last character of the ID is greater than the first character:
      • the person is 21 years old or older. They pay an additional $100 in taxes. Add this to their current tax amount. Display that they are 21 years of age or older, that there is an additional $100 tax, and display the new tax amount.
      • Otherwise the person is less than 21 years old. There is no additional tax. Display that the are under 21 years of age and do not pay the additional tax.
    • Then if the ASCII value of the fifth letter (remember indexing starts at 0) of the ID (as a capital letter) is divisible by 7
      • that person is a millionaire. Their tax is the larger of the current tax amount and $15,000. Display that they are a millionaire, that their tax is the larger of their current tax amount (display the value) and $15,000, and display their new tax amount.
      • Otherwise they are not. Display nothing.
    • Then if the ID contains the string "MED" (remember case does not matter in the ID):
      • then they are a medical professional. Their tax is reduced by $100. Display that they are a medical profession, they their tax is reduced by 100, and display the new tax amount.  
      • Otherwise they are not. Display nothing.
    • Then if the final tax amount is negative, change it to 0.
    • Finally, in one printf statement, display a message that tells the user the ID, the tax year, their annual income, and their final tax amount owed.
