PRACTICAL QUESTION                                                                                         

Tiger Construction Ltd signs a contract on 1 May 2018 to build a theme park. The construction is scheduled to commence on 1 July 2018 and the estimated date of completion is 30 June 2021. The total contract price is $5m and the cost of the park is initially estimated at $4.5m. The following data relates to the construction period:

Assume that cost (an input measure) is used as the basis for assessing progress on the construction contract.

Required

Determine the percentage of completion for 2019, 2020 and 2021.               

Calculate revenue and gross profit for 2019, 2020 and 2021.                           

Using the percentage of completion method, provide the journal entries for 2019, 2020 and 2021.                                                                                                              

Write a program in Java Using object Orientation Design to determine the status of Mini Van Sliding Doors. A logical circuit receives a different binary code to allow opening different doors. The doors can be opened by a dashboard switch, inside or outside handle. The inside handle will not open the door if the child safety lock is on or the master lock is on. The gear shift must be in the park to open the door.

1. A method must be written to indicate the gear shift status and return to main.
2. A method to display which door is open or can be opened.
3. A method to show the status of all doors
4. A method to convert the code to decimal and store in the text file (Character based) as a record.

** MUST USE constructors and methods. The methods should be instantiated by an object. Use simple main. The first bit Stream must be entered by users. The program needs to be interactive

I drive to school and am currently looking for a parking spot so I can walk to Jacob's. If I turn into a parking lot to look for a spot to park in that specific lot, the process of looking for a spot takes 1 minute of time whether I find a spot or not.  

Parking lot A is closest to Jacobs. If I get a spot here, it takes me 1 minute to walk into my class at the business school, however there is only a 10% chance I'll find a spot if I look.

Parking lot B is a 4-minute walk; if I pull in to look for a spot, there is a 30% chance I'll find a spot.

Parking lot C is an 8-minute walk; if I pull in to look for a spot, there is a 100% chance I will find a spot.  

Which strategy to find a parking spot is best for me (ie. which order should I check the parking lots for spots to park), assuming we are risk-neutral, and simply want to have the earliest expected arrival time to Jacob’s as possible? (Another way to say this is we want the smallest expected value of time spent getting to Hall).

Now, assume I am risk averse (let’s say that in this second case, my class starts in 10 minutes, and there is a large decrease in my utility if I am late for class). Is the best strategy the same as when I am risk-neutral, or has it changed?

The Business School at State University currently has three parking lots, each containing 155 spaces. Two hundred faculty members have been assigned to each lot. On a peak day, an average of 70% of all lot 1 parking sticker holders show up, an average of 72% of all lot 2 parking sticker holders show up, and an average of 74% of all lot 3 parking sticker holders show up.

a. Given the current situation, estimate the probability that on a peak day, at least one faculty member with a sticker will be unable to find a spot. Assume that the number who show up at each lot is independent of the number who show up at the other two lots. Compare two situations: (1) each person can park only in the lot assigned to him or her, and (2) each person can park in any of the lots (pooling). (Hint: Use the RISKBINOMIAL function.) If needed, round your answer to a whole percentage and if your answer is zero, enter "0".

b. Now suppose the numbers of people who show up at the three lots are highly correlated (correlation 0.9). How are the results different from those in part a? If needed, round your answer to a whole percentage.
