Question #4

DO NOT USE ANY NON-STANDARD LIBRARY. o All the required libraries have already been included. O DO NOT INCLUDE ANY OTHER LIBRARY INTO THE CODE. o DO NOT ALTER THE NAMES OF THE C FILES PROVIDED. o DO NOT ALTER THE NAMES AND PROTOTYPES OF THE FUNCTIONS. DO NOT ALTER THE CODE, ONLY ADD WHATS NEEDED TO MAKE IT WORK.

This is the code:

#include <stdio.h>

/*
* This function counts and returns the number of adjacent Up and Downs in an array of integers.
* In other words, you should count and return the number of changing directions in the sequence.
* This means, for instance, if the sequence is entirely ascending, or entirely descending, it should return 0.
* Examples:
* For the sequence {1,2,3,5} starting from 1, you say "Up, Up, Up", so it returns 0, (no changing direction)
* For the sequence {0,2,1,7} starting from 0, you say "Up, Down, Up", so it returns 2, (two times of changing directions or two adjacent up/downs)
* For the sequence {2,3,1,4,5,2,1} starting from 2, you say "Up, Down, Up, Up, Down, Down", so it returns 3, (three adjacent up/downs)
* For the sequence {4,3,2,1} starting from 4, you say "Down, Down, Down", so it returns 0, (no changing direction)

   printf("%d\n", adjacentUpDowns(a,4));   //Expected output is 0
   printf("%d\n", adjacentUpDowns(b,4));   //Expected output is 2
   printf("%d\n", adjacentUpDowns(c,8));   //Expected output is 3
   printf("%d\n", adjacentUpDowns(d,4));   //Expected output is 0
}

8. You begin to get tired and the book begins to slide down. The book begins to slide down, and you respond so it slides down at a constant velocity. How do each of the forces you have identified change from their magnitudes in part (a)? Explain how you know. (this question will not be auto-graded, answer fully)

9. If the book has a mass of 2 kg, the coefficient of friction between the sliding book and the wall is 0.4, how hard do you have to press on the book if it is sliding down with a speed of 2 cm/s? D2M

10. BCD on 9

Consider the S&P/ASX 200 option contracts that expire on 17th September 2020, with a strike price of 6050. On 24th July 2020, the S&P/ASX 200 index was priced at 6019.8. The annual standard deviation of S&P/ASX 200 stocks is 26%. The risk-free rate is 2.25% with annual compounding. Assume no dividends are paid on any of the underlying securities in the index.

Suppose that the manager did place the hedge in May. We are now on October 15th, 2020 and the plant has just taken delivery of the corn whose price she hedged. She is now managing price risk for the next corn intake, for mid-February, and is considering using a futures hedge to lock in a price. Which maturity should she use?

a. December 2020 (expires Dec. 15)

b. March 2021 (expires Mar. 15, 2021)

c. May 2021 (expires May, 2021)

d. Not enough information

Sheffield Co. had sales revenue of $550,900 in 2020. Other items recorded during the year were:

Prepare a single-step income statement for Sheffield for 2020. Sheffield has 100,700 shares of stock outstanding. (Round earnings per share to 2 decimal places, e.g. 1.48.)

A company purchased a piece of equipment for $40,000 on January 1, 2018. At that time the company estimated the equipment would have a 6-year useful life and no salvage value. The company used straight-line depreciation based on this information used through 2019. On December 31, 2020, the company determined the equipment instead has a 9-year useful life, with no salvage value. The company's tax rate has been 20% since 2015. What is the necessary adjustment to beginning retained earnings in 2020 for this change?

A machine cost $1,128,000 on April 1, 2020. Its estimated salvage value is $136,000 and its expected life is 4 years.

Calculate the depreciation expense by straight-line for 2020. (Round answer to 0 decimal places, e.g. 5,275.)

Calculate the depreciation expense by double-declining balance for 2021. (Round answer to 0 decimal places, e.g. 5,275.)

Calculate the depreciation expense by sum-of-the-years'-digits for 2021. (Round answer to 0 decimal places, e.g. 5,275.)

A4. The data below shows the weekly cases of Covid-19 for Ghana as at 19th June 2020 since the
first case was recorded on 2nd March 2020(Source: WHO).

It is being argued on public airwaves that, the average weekly cases in Ghana is more than 500.
By testing the claim of what is being said on airwaves using the Sign Test, compute the
significance probability of the test correct to 4 decimal places.
