HA, a weak acid, with Ka=1.0×10−8, also forms the ion HA−2. The reaction is HA(aq)+A−(aq)⇌HA−2(aq) and its K = 4.0.

1-) Calculate the [H+] in a 1.0 M solution of HA.

2-)Calculate the [A−] in a 1.0 M solution of HA

3-)Calculate the [HA−2] in a 1.0 M solution of HA.

Consider a PUT option. If, in a two-state model, a stock can take a price of $300 or $200, what would be the hedge ratio for each of the following exercise prices: $280, $270, $240, $200?  


b. What do you conclude about the hedge ratio as the option strike price becomes progressively more in the money?

- Increases to a maximum of 1.0

- Decreases to a minimum of 1.0

- Increases to a maximum of 0

- Decreases to a minimum of 0

- Increases to a maximum of -1.0

- Decreases to a minimum of -1.0

Use the dataset RuralLand.xls to test for Multicollinearity. Price is observed land price per acre excluding improvements; WL is the proportion of acreage that is wooded; DA is the distance from parcel to Sarasota airport; D75 is the distance form parcel to I-75; A is acreage of parcel; and MO is month in which the parcel was sold. Price is assumed to be dependent on these other factors.

Please provide a thorough walk through on analysis and any testing done as opposed to just posting the answers.

For the amusement of the guests, some hotels have elevators on the outside of the building. One such hotel is 300 feet high. You are standing by a window 100 feet above the ground and 150 feet away from the hotel, and the elevator descends at a constant speed of 30 ft/sec, starting at time

t = 0,

where t is time in seconds. Let θ be the angle between the line of your horizon and your line of sight to the elevator.

(a) Find a formula for

h(t),

the elevator's height above the ground as it descends from the top of the hotel.
h(t) =  

  

(b) Using your answer to part (a), express θ as a function of time

t.

θ(t) =  

tan−1(2−t5​)

Find the rate of change of θ with respect to t.

=  

(c) The rate of change of θ is a measure of how fast the elevator appears to you to be moving. At what height is the elevator when it appears to be moving fastest?

Park Corporation is planning to issue bonds with a face value of $700,000 and a coupon rate of 7.5 percent. The bonds mature in 6 years and pay interest semiannually every June 30 and December 31. All of the bonds were sold on January 1 of this year. Park uses the effective-interest amortization method and also uses a discount account. Assume an annual market rate of interest of 8.5 percent. (FV of $1, PV of $1, FVA of $1, and PVA of $1) (Use the appropriate factor(s) from the tables provided. Round your final answer to whole dollars.) Required: 1. Prepare the journal entry to record the issuance of the bonds. (If no entry is required for a transaction/event, select "No journal entry required" in the first account field.)

2. Prepare the journal entry to record the interest payment on June 30 of this year.

3. What bond payable amount will Park report on its June 30 balance sheet?

A question of interest to game managers is the hunting strategy of predators. Do they just take the first prey that comes along, or are the selective? In a study of winter prey selection in a National Park, radio-tagged wolves were observed to have killed prey according to the table below. Wolves were identified as the predators by their tracks in the snow. At the most recent census in the National Park there were about 3,500 white-tailed deer, 1,000 elk, and 500 moose.

                                                                               Prey Selection by Wolves

Do these data provide sufficient evidence at the a=.05 level that the wolves are not selecting their prey at random? That is, is there evidence that the proportion of deer, elk, and moose killed by wolves are not in the same proportion as in the park population? Justify your response with an appropriate statistical analysis. Using a=.05

1. Dr. Chong, a citizen of Singapore, traveled to Singapore from the United States recently and is quarantined in a 4-star hotel at government expense. The hotel charges SGD 300 per night (with breakfast). Aiden expects to be quarantined for 14 days. What is the cost to the government of the two-week hotel stay in U.S. dollars?
2. Given the following prices, calculate the price of pounds in dollars (how many dollars it takes to buy a pound): $1.08374/€, €1.14212/£         
3. Assume the following: Spot rate ¥110/$ and one-year interest rates in Japan and the U.S. are 2% and 4%, respectively. What is the expected exchange rate in a year?
4. You are trying to decide whether to invest in the U.S. or Switzerland for the next 3 months. The spot rate is $.6667/CHF, the 90-day forward is $.6756/CHF, and the annualized rates on the U.S. T-bill and Swiss government 3 month bonds are 10% and 4.5333%. Is it better to invest in the U.S. or Switzerland?

Milky entered into a contract for the hire of 6 rooms in New Castle Hotel in    Kowloon West. The purpose of the contract was to watch the fireworks gala in the Victoria Harbour on the 1st July (Reunification Day) through the windows of the rooms. Milky planned to invite her close friends and their families to stay in the 6 rooms to enjoy the fireworks. Just two hours before start of the fireworks, the Hong Kong Police Force received a serious threat from some terrorist organizations that they would launch large scale attack to the crowds who gathered to watch the fireworks. The Hong Kong Government immediate ordered the cancellation of the fireworks and gave an order that this kind of gala will not be launched at least for five years. Milky, having already paid a deposit, refused to pay the balance of the room charges. The hotel took legal action to recover the balance.

Required:

Analyse the chance of success by the hotel and explain in detail the legal principles that you base on for analysis.

A common room pricing strategy used by hotels is to price each day for which this room can be reserved, as discussed in the lecture. The price of a stay is then the sum of the day prices spanned by the stay (i.e., checkin and checkout dates). Full-service airlines, as you may already know, typically price itineraries. a. Explain the differences between day pricing of hotel rooms and the pricing of airline itineraries? (i.e. What is the product?, What is the resource?, and What is being priced?) b. Consider the purchase of a customized laptop on Dell’s website. Customization involves choosing laptop components that have different price points. The choice of components determines the ultimate price of the laptop. Explain why the day pricing of hotel rooms is a special case of the problem of pricing laptop components being shown to customers in Dell’s website. c. Why is Dell’s pricing problem more complicated than the pricing problem faced by a hotel?
