Parker Plastic, Inc., manufactures plastic mats to use with rolling office chairs. Its standard cost information for last year follows:

Write a function ‘filter_wave(wave,n)’ and this will produce a new wave which is a smoothed version of the input ‘wave’ adhering to the following rules. The input parameter n will be explained later in part 2. • In the new wave, for every position i, it is the weighted sum of three positions of the original wave. More preciously, the new wave value in position i will be equal to new_wave[i] = wave[i-1] * 0.2 + wave[i]*0.6 + wave[i+1]*0.2 • Let len(wave) be L. The above calculation requires access to wave[-1] and wave[L] which do NOT exist in the original wave. You may assume that both wave[-1] and wave[L] are 0. • You should NOT modify the original wave input • And all the number in the new wave will be integers. You can simple use the function int() to convert any number into an integer. • Your function should return the new wave as a list.

Finally, modify the function ‘filter_wave(wave,n)’ for n ≥ 0. And this will repeat the filtering n times to the wave accumulatively and produce an even smoother wave. You still need to adhere to the rules mentioned in Part 1. Here is the expected wave for filter_wave(original_wave_sample,10)

Please solve for part C! Thank you !

On November 14, Thorogood Enterprises announced that the public and acrimonious battle with its current CEO had been resolved. Under the terms of the deal, the CEO would step down from his position immediately. In exchange, he was given a generous severance package. Given the information below, calculate the cumulative abnormal return (CAR) around this announcement. Assume the company has an expected return equal to the market return. (A negative value should be indicated by a minus sign. Leave no cells blank - be certain to enter "0" wherever required. Do not round intermediate calculations. Round your answers to 1 decimal place.)

Lucy and Henry each have $6516. Each knows that with 0.1 probability, they will lose 85% of their wealth. They both have the option of buying α units of insurance, with each unit costing $0.1. Each unit of insurance pays out $1 in the event the loss occurs. The cost of the insurance policy is paid regardless of whether the loss is incurred. Lucy's utility is given by ??(?)=?, Henry's utility is given by ??(?)= sqrt(x)

Answer the following:

(If rounding is needed, only round at the end and write your answer to three decimal places.)

a) (0.5 marks) Without insurance, what is the expected value of the loss?  

b) (0.5 marks) For Henry, facing the "lottery " above without any insurance is as bad as losing how many dollars for sure?

c) (1 mark) Find Lucy's utility maximising choice of α. If more than 1 exist, enter the largest α.

d) (1 mark) Now suppose insurance costs $0.2. Find Lucy's utility maximising choice of α. If more than 1 exist, enter the largest α.

e) (1 mark) What is Henry's utility maximising choice of α with the new price of 0.2? If more than 1 exist, enter the largest α.

1. An increase in revenue always:
   1. increases stockholders' equity.
   2. increases assets.
   3. decreases stockholders' equity.
   4. decreases assets.

2. Which of the following journal entries would decrease stockholders' equity?
   1. Debit Prepaid Insurance and credit Cash.
   2. Debit Deferred Revenue and credit Service Revenue.
   3. Debit Supplies and credit Accounts Payable.
   4. Debit Insurance Expense and credit Cash.

3. In April, the Surf and Sand Hotel books and accepts a cash payment for $25,600 for vacation services to be provided during in July. The journal entry recorded in April will include a debit to:
   1. Cash and a credit to Deferred Revenue.
   2. Accounts Payable and a credit to Service Revenue.
   3. Accounts Receivable and a credit to Service Revenue.
   4. Prepaid Expenses and a credit to Service Revenue.

discuss at least one pro and con of putting a price on a specific environmental good of your choosing. Using a specific resource or environmental amenity, discuss:

• What characteristics of the good restrict market valuation?
• In what instances would we want to put a price on the good?
• In what cases can a price actually harm the resource in question rather than help it?
• What estimation techniques did the researchers use in this National Park study and is this tool the best tool for estimating the value of your chosen amenity? Why or why not?
• In your response to a classmate's post, offer an alternative valuation method and briefly explain why it would be an acceptable tool for the amenity discussed.

A New York City daily newspaper called "Manhattan Today" charges an annual subscription fee of $108. Customers prepay their subscriptions and receive 270 issues over the year. To attract more subscribers, the company offered new subscribers the ability to pay $110 for an annual subscription that also would include a coupon to receive a 40% discount on a one-hour ride through Central Park in a horse-drawn carriage. The list price of a carriage ride is $100 per hour. The company estimates that approximately 30% of the coupons will be redeemed.

Required:

Prepare the journal entry to recognize the sale of 10 new subscriptions, clearly identifying the revenue or unearned revenue associated with each performance obligation.
