Conch Republic Electronics Part 1

Conch Republic Electronics is a midsized electronics manufacturer located in Key West, Florida. The company president is Shelley Couts, who inherited the company. When it was founded over 70 years ago, the company originally repaired radios and other household appliances. Over the years, the company expanded into manufacturing and is now a reputable manufacturer of various electronic items. Jay McCanless, a recent MBA graduate, has been hired by the company's finance department.

One of the major revenue-producing items manufactured by Conch Republic is a smart phone. Conch Republic currently has one smart phone model on the market, and sales have been excellent. The smart phone is a unique item in that it comes in a variety of tropical colors and is preprogrammed to play Jimmy Buffett music. However, as with any electronic item, technology changes rapidly, and the current smart phone has limited features in comparison with newer models. Conch Republic spent $750,000 to develop a prototype for a new smart phone that has all the features of the existing smart phone but adds new features such as WiFi tethering. The company has spent a further $200,000 for a marketing study to determine the expected sales figures for the new smart phone.

Conch Republic can manufacture the new smart phones for $215 each in variable costs. Fixed costs for the operation are estimated to run $6.1 million per year. The estimated sales volume is 155,000, 165,000, 125,000, 95,000, and 75,000 per year for the next five years, respectively. The unit price of the new smart phone will be $520. The necessary equipment can be purchased for $40.5 million and will be depreciated on a seven-year MACRS schedule. It is believed the value of the equipment in five years will be $6.1 million.

As previously stated, Conch Republic currently manufactures a smart phone. Production of the existing model is expected to be terminated in two years. If Conch Republic does not introduce the new smart phone, sales will be 95,000 units and 65,000 units for the next two years, respectively. The price of the existing smart phone is $380 per unit, with variable costs of $145 each and fixed costs of $4.3 million per year. If Conch Republic does introduce the new smart phone, sales of the existing smart phone will fall by 30,000 units per year, and the price of the existing units will have to be lowered to $210 each. Net working capital for the smart phones will be 20 percent of sales and will occur with the timing of the cash flows for the year; for example, there is no initial outlay for NWC, but changes in NWC will first occur in Year 1 with the first year's sales. Conch Republic has a 35 percent corporate tax rate and a required return of 12 percent.

Shelley has asked Jay to prepare a report that answers the following questions.

Conch Republic Electronics Part 2

Shelley Couts, the owner of Conch Republic Electronics, had received the capital budgeting analysis from Jay McCanless for the new smart phone the company is considering. Shelley was pleased with the results, but she still had concerns about the new smart phone. Conch Republic had used a small market research firm for the past 20 years, but recently the founder of that firm retired. Because of this, she was not convinced the sales projections presented by the market research firm were entirely accurate. Additionally, because of rapid changes in technology, she was concerned that a competitor could enter the market. This would likely force Conch Republic to lower the sales price of its new smart phone. For these reasons, she has asked Jay to analyze how changes in the price of the new smart phone and changes in the quantity sold will affect the NPV of the project.

Shelley has asked Jay to prepare a memo answering the following questions.

QUESTIONS

1.What is the payback period of the project?

2.What is the profitability index of the project?

3.What is the IRR of the project?

4.What is the NPV of the project?

5.How sensitive is the NPV to changes in the price of the new smart phone?

6.How sensitive is the NPV to changes in the quantity sold of the new smart phone?

PLEASE ATTATCH EXCEL FILE FOR ANSWER THANK YOU!!!!!

A study shows that the amount of time spent by millennials playing video games is 22.6 hours a month, with a standard deviation of 6.1 hours. A bright UWI stats student has doubts about the study’s results. She believes that they actually spend more time. The student tries to resolve her doubts, and collects a random sample of 60 millennials, asking them to keep a daily log of their video game playing habits. Millennials in the sample played an average of 24.2 hours per month. (a) If the null hypothesis is true, describe the sampling distribution of the mean number of hours spent playing video games. [5 marks] (b) Calculate the probability of randomly choosing a sample in which the average number of hours of video games played was 24.2 or more. [5 marks] (c) No hard and fast rule exists which divides the boundary between p-values for which we reject the null and those for which we feel the null is plausible. However p = 0.05 and p = Xi ~ Poisson : e?(2? ) (2?) X X ! , X = 0,1,2,… X 2 0.01 are two commonly used thresholds. Under these thresholds, should the student reject the null hypothesis? [5 marks] (d) Suppose the student doubted the study’s findings but had no prior expectation of whether they were too high or too low. Perhaps she should determine the probability of randomly choosing a sample in which the average number of hours spent playing video games was as extreme or more extreme that 24.2 hours. Should she reject the null hypothesis in this case? [5 marks] (e) Would a larger sample with the same mean of 24.2 have provided stronger evidence of a difference from the original study’s mean? Explain. [5 marks]

REQUIREMENTS:

1. Write a function that matches the following declaration:

   int InRectangle( float pt[2], float rect[4] );

2. Argument pt[2] defines a point on the plane: pt[0] is the x-coordinate, pt[1] is the y-coordinate.
3. Argument rect[4] defines a rectangle on the same plane. rect[0] and rect[1] define the x- and y- cordinates respectively of one corner of the rectangle. rect[2] and rect[3] define the opposite corner.
4. Coordinates may be any valid floating point value, including negative values.
5. The function returns int 0 (false) for any point that lies outside the rectangle, and 1 (true) for any other point (i.e. points inside and on the boundary of the rectangle).

TESTS:

Find all rectangles filled with 0

We have one 2D array, filled with zeros and ones. We have to find the starting point and ending point of all rectangles filled with 0. It is given that rectangles are separated and do not touch each other however they can touch the boundary of the array.A rectangle might contain only one element. In Javascript preferred.

Examples:

input = [
            [1, 1, 1, 1, 1, 1, 1],
            [1, 1, 1, 1, 1, 1, 1],
            [1, 1, 1, 0, 0, 0, 1],
            [1, 0, 1, 0, 0, 0, 1],
            [1, 0, 1, 1, 1, 1, 1],
            [1, 0, 1, 0, 0, 0, 0],
            [1, 1, 1, 0, 0, 0, 1],
            [1, 1, 1, 1, 1, 1, 1]
        ]


Output:

4. T          F          A storm with a return period of 25 years will occur only once every 25 years.

5. A drainage basin’s “time of concentration” means the time

1. the time for the first raindrop to flow down the steepest slope in the area.
2. the time to drain the drainage area after the rain stops.
3. the longest time of flow to the point of interest.
4. the time that is equal to the duration of the rainfall event.

6. (12 pts) The three general types of flow that could occur along the hydraulic path in a drainage area are ______________________________ flow, ______________________________flow, and ______________________________ flow.

7. The average rainfall rate in inches/hour is called the

1. duration.
2. return period.
3. frequency.
4. intensity.

In this assignment we will be working with both text strings and a user input integer array from the data segment. The goal of the assignment is to have the user choose the number of items that they want to have in an array (we will keep it a small number for now, 1-10) and then enter those values which we will store into our array. We then want to allow them to search for a specific item in the list of number that they just entered and report if the number was found or not. Requirements:

• Name your program P02LastNameFirstName.asm

• You must make use of the data segment in order to both have strings to prompt the user and to have a location to store the values the user inputs.

• String prompts and information about the program must be given to the user in a well formatted and logical fashion so that someone using the program with no knowledge about it would understand what is happening.

• The user must be allowed to choose the number of items they are going to input, though we will limit it to a smaller number (1-10).

• The user can then enter their integers, which must be stored in the array defined in the data segment.

• You will then prompt the user for an integer to search for and then search through the input array to see if it is present. • If it is, report success. If it is not found, report failure.

Hints: • Remember that the data segment holds the larger pieces of data and the text segment has the instructions that will be run. • You can define an area for more data than you use. • Using “.align #” in the data segment can help if your array is not aligned on memory boundaries (an error you may encounter). The # refers to the boundary you want to align on, check the tooltip in MARS for more information. The value 2 is the likely choice. • Keep in mind that since we are working with integers, that we will need to move through our array with their size in mind.

(i) Zin, the input impedance of the line at the generator end;

(ii) input current I i and voltage Vi ;

(iii) time-average power delivered to the line, = 0.5 x Re{V .I*};

(iv) load voltage VL, and current, IL; and

(v) the time-average power delivered to the load, = 0.5 x Re{VL .IL*};how does compare to ? Explain?

(vi) compute the time average power delivered by the generator, Pg , and the time average power dissipated in Zg . Is conservation of power satisfied?. [12 marks]

(b) A team of scientists is designing a radar as a probe for measuring the depth of the ice layer over the antarctic land mass. In order to measure a detectable echo due to the reflection by the ice-rock boundary, the thickness of the ice sheet should not exceed three skin depths. If ε' = 3 a n d ε'' = 10-2 for ice and if the maximum anticipated ice thickness in the area under exploration is 1.2 km, what frequency range is useable with the radar? [6 marks]

(c) A 0.5-MHz antenna carried by an airplane flying over the ocean surface generates a wave that approaches the water surface in the form of a normally incident plane wave with an electricfield amplitude of 3,000 (V/m). Sea water is characterized by μr = 1, εr = 72, and σ = 4 S/m. The plane is trying to communicate a message to a submarine submerged at a depth d below the water surface. The submarine’s receiver requires a minimum signal of 0.01 μV/m amplitude, what is the maximum depth d to which successful communication is still possible? [7 marks]
