Write a method that displays every other element of an array.

Write a program that generates 100 random integers between 0 and 9 and displays the count for each number. (Hint: Use an array of ten integers, say counts, to store the counts for the number of 0s, 1s, . . . , 9s.)

Write two overloaded methods that return the average of an array with the following headers:   

  public static int average(int[] intArray)     

  public static double average(double[] dArray)

Also, write a test program that prompts the user to enter ten double values, invokes the correct method, and displays the average value.

Given this array, write the code to find the smallest value in it:

  int[] myList = new myList[n];

1. Compile and run shell0.c file

2. Design and implement shell1.c program to handle "exit" command to terminate the program.
That is, if the user input-string is "exit", then the program terminates.

3.Design and Implement shell2.c to implement a signal handler to handle ctrl+C (SIGINT) as listed below

            void sig_int(int signo) { printf("\nCaught SIGINT!\n"); }

Here is shell0.c file

• Create a set of use case documents and use case diagrams for a university library borrowing system (Do not worry about catalogue searching etc.)
• The system will record who has borrowed what books. Before someone can borrow a book, he or she must show a valid ID card that is checked to ensure that it is still valid against the student database maintained by the registrar's office.
• The system must also check to ensure that the borrower does not have any overdue books or unpaid fines before he or she can borrow another book.

A certain weak acid, HA, with a Ka value of 5.61×10−6, is titrated with NaOH.

A solution is made by titrating 8.00 mmol (millimoles) of HA and 1.00 mmol of the strong base. What is the resulting pH?

More strong base is added until the equivalence point is reached. What is the pH of this solution at the equivalence point if the total volume is 46.0 mL ?

No idea how to do this! Please explain..thanks!

Q1: Create a class named Triangle, the class must contain:

• Private data fields base and height with setter and getter methods.
• A constructor that sets the values of base and height.
• A method named toString() that prints the values of base and height.
• A method named area() that calculates and prints the area of a triangle.

• Draw the UML diagram for the class.
• Implement the class.

Q2: Write a Java program that creates a two-dimensional array of type integer of size x by y (x and y must be entered by the user). The program must fill the array with random numbers from 1 to 100. The program must prompt the user to enter a search key between 1 and 100. Then, the program must check whether the search key is available in the array and print its location.

Here is a sample run:

Enter the number of rows: 5

Enter the number of columns: 5

Enter a search key between 1-100: 27

The key you entered is available at row 3, column 2.

Here is another sample run:

Enter the number of rows: 5

Enter the number of columns: 5

Enter a search key between 1-100: 33

The key you entered is not available in the array.

In December 2016, Learer Company’s manager estimated next year’s total direct labor cost assuming 30 persons working an average of 2,500 hours each at an average wage rate of $30 per hour. The manager also estimated the following manufacturing overhead costs for 2017.

At the end of 2017, records show the company incurred $1,566,000 of actual overhead costs. It completed and sold five jobs with the following direct labor costs: Job 201, $608,000; Job 202, $567,000; Job 203, $302,000; Job 204, $720,000; and Job 205, $318,000. In addition, Job 206 is in process at the end of 2017 and had been charged $21,000 for direct labor. No jobs were in process at the end of 2016. The company’s predetermined overhead rate is based on direct labor cost.

Required
1-a. Determine the predetermined overhead rate for 2017.
1-b. Determine the total overhead cost applied to each of the six jobs during 2017.
1-c. Determine the over- or underapplied overhead at year-end 2017.
2. Assuming that any over- or underapplied overhead is not material, prepare the adjusting entry to allocate any over- or underapplied overhead to Cost of Goods Sold at the end of 2017.

Design a multiplexed communication system that can be used for 1 of 4 senders (sources) to send 3 bits to 1 of 2 receivers (destinations) using a 3-bit 4×1 multiplexer and a 2-bit 1×2 demultiplexer. Assume that the most significant of the 3 bits denotes the header containing the destination ID and that the 2 less significant bits denote the message. Represent both the 3-bit 4×1 multiplexer and a 2-bit 1×2 demultiplexer using block diagrams with all inputs and outputs labeled. Show which outputs of the multiplexer connect to which inputs of the demultiplexer!

After paying $3 million for a feasibility study, Stanley wrote a proposal with the following cash flow estimates for a 25-year capital project.

Equipment cost: $34 million, Shipping costs: $1 million, Installation: $19 million, Salvage: $4, Working capital investment: $2 million, Revenues are expected to increase by $20 million per year and cash operating expenses by $9 million per year.

The firm’s marginal tax rate is 40 percent, its weighted average cost of capital is 9%, and the firm requires a 3 year payback. Assume straight-line depreciation.

Evaluate the project using NPV, IRR, PI, and PB.

Answers:

IO = $56 million

Δ D = $2 million

NCF1-25 = $7.4 million

NCF25 = $6 million

NPV = $17.38 million > 0, so Accept

IRR = 12.60% > 9%, so Accept

PI = 1.31 > 1, so Accept

PB = 7.57 years > 3 so Reject

ACCEPT the project

Draw an ER diagram and write a database design outline for the following prompt:

You run a coaching service to help high school students prepare for the SAT exam. You have a staff of coaches, each of which has an employee ID, an hourly rate (such as $20 per hour), and personal information consisting of their first name, last name, middle name/initial, address information, phone number, mobile phone number, and e-mail address. For each high school student, you want to keep similar personal information and a student ID number, date of birth, and expected date of graduation from high school. Coaching takes place in sessions, to each of which you assign a unique ID number. Each session consists of one coach and one student. In addition to being able to identify the coach and student involved in each session, you want to store its start date/time and end date/time.

1- Innovation and risk taking, which is the degree to which employees are encouraged to be both innovative and take risks.

2- Attention to detail, or the degree to which employees are expected to exhibit precision, analysis, and attention to detail.

3- Outcome orientation, or the degree to which management focuses on results rather than on processes used to achieve them.

4- People orientation, the degree to which management decisions consider the effect of outcomes on people within the organization.

5- Team orientation, described as the degree to which work activities are organized around teamsrather than individuals.

6- Aggressiveness, or the degree to which people are aggressive and competitive.

NOK Plastics is considering the acquisition of a new plastic injection-molding machine to make a line of plastic fittings. The cost of the machine and dies is $125,000. Shipping and installation is another $8,000. NOK estimates it will need a $10,000 investment in net working capital initially, which will be recovered at the end of the life of the equipment. Sales of the new plastic fittings are expected to be $350,000 annually. Cost of goods sold are expected to be 50% of sales. Additional operating expenses are projected to be $115,000 per year over the machine’s expected 5-year useful life. The machine will depreciated using a 5-year MACRS class life. The equipment will be sold at the end of its useful life (5 years) for $35,000. The tax rate is 25% and the relevant discount rate is 15%. Calculate the net present value (NPV), internal rate of return (IRR), payback period (PB), and profitability index (PI) and state whether the project should be accepted.

A ground state hydrogen atom absorbs a photon of λ = 94.91 nm, exciting the electron to a higher energy (quantum) level. The electron then decays to a lower, intermediate energy level, emitting a photon of λ = 1281 nm. From that intermediate energy level the electron decays back to the ground state, emitting another photon. a) What is the highest energy level attained by the electron?

b) What was the intermediate energy level of the electron?

c) What was the λ of the second photon?
