Use this information to determine your economy’s original AE_P, A_P, and IS curve.

C=500-10r+0.9Y_D

Ip=250-40r

G=390

T=100+0.1Y

X=600

M=400+0.06Y

1. Use the four graphs we developed in class to determine the IS curve for this economy with r=0 and r=5. Show how the following change would affect this economy. You need to determine what has changed in the economy, what parts of the economy it affects, and how it changes the IS curve. Be sure to address any shifts as well as changes in slopes that may occur. You must show these changes mathematically, graphically, and then describe these changes verbally.
   1. M = 400+0.01Y
2. Now, what happens to the economy when this change occurs? Return to your original equations. Suppose Consumers decide that credit is a good way to finance their expenditures on durables, so they become more interest sensitive, C=500-50r. Determine what has changed in the economy, what parts of the economy it affects, and how it changes the IS curve. Be sure to address any shifts as well as changes in slopes that may occur. Show these changes mathematically and graphically.

this is a two part answer please help :)

Estimate how many deaths there are annually from tornado and drowning in the United States. Provide an actual number in your answer and explain statistically how you came to that answer.

Info:

DROWNINGS:

From 2005-2014, there were an average of 3,536 fatal unintentional drownings (non-boating related) annually in the United States — about ten deaths per day.¹ An additional 332 people died each year from drowning in boating-related incidents.

TORNADOS:

The following scenarios are based on actual returns and situations that have occurred in this years VITA program. The responses provided here would be similar to those you would provide to actual taxpayers in the event a similar situation would occur.

Scenario

Inez Sanchez, age 49, ITIN # 933-12-1987 is married but has been separated from her husband since March 3, 2017. She is a housekeeper for Acme Hotels Inc. She has four daughters, all born and raised in the U.S. who lived with her the entire year who she fully supports. No one had any health insurance for the entire year

Name Date of Birth Social Security Number Earnings

Polet Sanchez 09/09/2006 454-11-2222 $0

Jessica Sanchez 07/07/2004 453-11-2222 $0

Stephanie Sanchez 05/05/2002 452-11-2222 $0

Juanita Sanchez 03/03/1995 451-11-2222 $8000

For legal reasons, she tells you that she wants to file a paper return. She also wants her refund mailed to her.

Inez’s Refund for 2019 was $4,600.

After completing Inez’s return, she mentions to you that many of her friend’s and co-workers who make about the same amount of money and have the same number of children got almost double of what she is getting?

Obviously, one of the major reasons is that she has an ITIN number and not a social security number which does not make her eligible for EIC. Another reason is because she has a child who is over 24 and makes more than $4250. Lastly she has a child who turned 17 in 2019 and is no longer eligible for the child tax credit

As usual the taxpayer is upset and believes that the return was not completed correctly. As the tax preparer or quality reviewer, your job is to explain to the taxpayer why your work is correct and why this changed occur

In the preparation process, all UIW-VITA procedures were followed and the results of your return are 100% accurate.

Instructions

For the purposes of this scenario, you must explain to Inez why her refund is the way it is. As the tax preparer or quality reviewer, your job is to explain to the taxpayer why your work is correct and why this return resulted in the refund that it did. Remember, you are dealing with a taxpayer who is unhappy with your work. For this assignment, you are not required to re-explain to me the results of the return again. Rather, I am looking for a procedure you would use to assure the taxpayer the result of your work are accurate. Remember, all of the policies and procedures that were used in the preparation process. Be creative.

P. S- This is a class related to tax in USA.

CASE 1-WI-FI INC.

OVERVIEW

Attach Wi-Fi to a broadband modem and any nearby computer equipped with Wi-Fi receptors and you can log on to the Net. Wi-Fi networks, known as hot spots have popped up so tfast that more than 18 million people worldwide have logged on, and the numbers are growing daily. The challenge is to transform this innovation into a global business, developing coherent and dependable networks, coming up with billing systems, roaming agreements, and technical standards. Wi-Fi could extend dramatically the range and expanse of the Web, changing its vary nature.

The potential productivity gains are so compelling that many companies are investing in custom-built systems, without waiting for a fine-tuned industrial version of Wi-Fi to hit the market. As more companies compete, prices are plummeting. It costs only $2,000 to install a hot spot, one-fifth what it was two years ago. Although corporations are interested in the power and flexibility of Wi-Fi networks, many are postponing rollouts in strategic areas until they are convinced it is secure. A possible solution is the overlap between Wi-Fi and the high-speed cellular system, known as Third Generation (3G) that also promises a wireless internet access with broader coverage.

The benefits are impressive: Wi-Fi turns every machine, from laptops to cash registers into network devices. And it fuels demand for always-on broadband connections. The consumer-electronics industry is counting on Wi-Fi, to link a host of appliances in the home. Cellular manufacturers are working on Wi-Fi phones that would let people move seamlessly from Wi-Fi to cellular networks. Starbucks and McDonald’s have installed Wi-Fi networks in their stores to attract new customers and boost sales.

The challenge is to build Wi-Fi into a solid pillar of the networked world. Intel assigned 800 engineers to work on Wi-Fi and in December 2002 joined IBM and AT&T to launch Cometa to build and have running 5,000 hot spots by March 2004. Intel is also building new chips; The Centrino family of chips embeds a Wi-Fi receptor into a laptop computer. Every Dell computer laptop and 70% of H-P consumer offerings will be Wi-Fi ready. However, Wi-Fi isn’t likely to become rock-solid standard until hot spots are dependable, and security systems satisfy the most demanding customers.

DISCUSSION QUESTIONS:

1. Define the product-market within which wireless networks are positioned.

B)Analyze the wireless network market, forecast the future directions of the market, and identify the possible consequences.

C)Indicate possible variables that may be useful in segmenting the wireless networks market

D)-Discuss the innovation challenges confronting companies competing in the wireless network market.

Kermit (a 6.0kg amorous amphibian) and Miss Piggy (a 10.0kg bacon beauty) find themselves in a pretty precarious predicament. While ascending a mountain in the Alps, they trip on a slippery slope. Since frog friction is very low (u_k?=0.22), Kermit finds himselfhurriedly hurtling toward disaster. Just as Kermit is about to fly over the edge, Miss Piggy lets go of the rope and they both fall to the ground, 227m below. How far apart are they and where will they land? Kermit is 50m away from the edge of the cliff and Miss Piggy is hanging off the edge of the cliff (they are attached by hanging onto a rope). No angle of inclination is given and the direction at which the frogs falls (ex: out horizontally) is not given. The frog is on the cliff and the pig is hanging off the cliff (so the pig will fall down and the frog will slide to the left until it falls). The frog is 50m from the edge of the cliff.

The option writer in Example 1.6.6 sells a digital option to a speculator. This amounts to a bet that the asset price will go up. The payoff is a fixed amount of cash if the exchange rate goes to $165 per £100, and nothing if it goes down. If the speculator pays $10 for this bet, what cash payout should the option writer be willing to write into the option? You may assume that interest rates are zero.

(Example 1.6.6 -Suppose that in the US dollar markets the current Sterling
exchange rate is 1.5 (so that £100 costs $150). Consider a European call option that
offers the holder the right to buy £100 for $150 at time T . The riskless borrowing
rate in the UK is u and that in the US is r . Assuming a single period binary model in
which the exchange rate at the expiry time is either 1.65 or 1.45, find the fair price
of this option.)

January of 1999, the German Auto Bild magazine randomly tested different tread patterns across all tire brands as their journalists toured from the UK to the Bulgarian coast. They discovered on one leg of the tour that out of 100 tires, or 12%, shortcomings were due to defective sidewall wire. On another leg they found 125 tires, 15% of the defects were due to poor vulcanization.

a) Find an appropriate 95% confidence interval. Explain the difference in outcomes. Let poor vulcanization represent sample #1.

b) Use your confidence interval to explain the difference in outcomes. 2

c) An expert at TUV  thought defects due to wire imperfections were more common than poor vulcanization issues. Reexamine the question in part “b” using a hypothesis test to determine if you support this German regulator’s expert opinion?

Five housing policies are described below, based on examples of measures that have been introduced or proposed in the UK, in response to a chronic shortage of affordable houses in many regions.

Drawing on the module material, write an essay that explains, using the ‘demand-and-supply’ model, the likely impact of each policy on the equilibrium quantity and price of houses, and how this might affect the UK’s affordable housing shortage.

Policy 4

The government has introduced a three-per-cent stamp duty surcharge that property owners are liable to. Some observers have said that this would push amateur buy-to-let landlords out of the market, as they are less well resourced to cope with the tax change compared to corporate developers. Most of the landlords who might be pushed out of the letting market by this measure are wealthy parents investing for their children’s future or those who have inherited properties.
