The advertising alternatives for a company include television, radio, and newspaper advertisements. The costs and estimates for audience coverage are given in following table:
|
television |
newspaper |
radio |
|
|
Cost per advertisement |
$ 2000 |
$ 600 |
$ 300 |
|
Audience per advertisement |
100,000 |
40,000 |
18,000 |
The local newspaper limits the number of weekly advertisements from a single company to ten. Moreover, in order to balance the advertising among the three types of media, no more than half of the total number of advertisements should occur on the radio, and at least 10% should occur on television. The weekly advertising budget is $18,200. Formulate the model for maximizing the total audience number?

Scenario 1:
Upon entering the classroom you notice two small glass tanks on the table. One of them contains many active crustaceans (Daphnia) swimming around. The other tank is cloudy and it appears as though all of the Daphnia are dead! You also notice a half-empty bottle of glucose in the trashcan. Your mission is to figure out what happened and why.
You have at your disposal the following items:
Microscope, slides, coverslips, etc.
Biuret and Benedict’s reagents and the necessary
equipment to perform these tests
1. What are your observations?
2. Could there be something in the water that killed
the Daphnia? What could that something be?
3. Formulate a hypothesis as to what you think might be in the “death” tank based simply on the few observations you have at the moment.
4. What experiment would you perform to test your
hypothesis?
5. Let’s assume the results of your experiment support your hypothesis. (Check with instructor, then proceed.) State the results of your experiment.
6. Given that your hypothesis is supported, propose an
explanation as to why the Daphnia died in terms of osmosis,
diffusion, tonicity and the effects of hyper/hypo-tonic solutions
on living cells.
List the four steps of the scientific method and describe what you did in the above scenario as it relates to each of those steps.
Scenario 2:
1. You are walking through the woods when you discover a small twitching blob. You think it might be alive so you bring it to class. Unfortunately by the time you get to class, it is no longer twitching. Your instructor decides to let you dissect it. When you cut the blob open you see a round mass of tissue in the center of the blob so you cut into it. You make a slide from that tissue and look at it under the microscope. What you see is a confusing mass of cells. It appears as though the cells have branches. Within the cell body you see a single nucleus. What do you think this tissue/cell type might be? And what would its function be?
2. Next you remove a piece of some very tough tissue.
Under the microscope you see linear strands of fibers that appear
to have striations in them. You wonder what would happen if you
applied an electric current to this tissue in the blob. Your
instructor gets an electrode and applies a mild electric current.
The tissue twitches! What type of tissue do you think this is? What
is its function?
3. With all of this cutting, the blob begins to leak.
You examine the fluid under the microscope and see many individual
cells all with a nucleus. What type of cells do you think these
are? Which other animal cell type do these cells resemble?
Scenario 3:
It’s twenty past the hour and you are late to biology lab. When you arrive, you find your classmates gathered outside the door and the Professor is nowhere to be found. You then notice that everyone is hovered around some spatters of red liquid inside the doorway. Has your professor been injured? You’d better find out.
What are your observations?
What are some hypotheses you could make about the situation based on your observations?
You and your classmates decide to examine the red liquid to find out exactly what it is. Your initial thought is to see what you can find under the microscope. You first need to prepare your slide. What would you need and how would you do this?
After you get the slide on the microscope all you see is darkness. What might be the problem?
Describe how you would manipulate the microscope to first center your specimen and then focus in on your image.
After some adjustments, you are able to focus on some tiny oval shaped structures. Each contains a purple stained dot in the center. As you scan around you also see some smaller, rounder structures that are also stained purple. Could this be the blood of you missing Professor or is there no cause for alarm?
Scenario 4:
Your pet dog has a stomach ache. The veterinarian, in order to help determine the cause of the ache, will attempt to identify the contents of its stomach. What tests could the vet perform and what results might you expect him/her to find?
Scenario 5:
You return from a bathroom break during your lab class on diffusion and osmosis, having just drank half a bottle of water. You return to find that your water has been moved and your lab partners are looking your way, pointing to the bottle, and snickering. You then catch a glimpse of an empty salt packet on the table. Are your lab partners trying to be funny? How would you determine whether or not they had poured the salt in your water without drinking it?

A loan of $3,200 is obtained at 8.4% payable monthly and is due in six years. To accumulate the principal the borrower will make monthly deposits into a sinking fund which earns 7.2% interest compounded monthly. Determine the total periodic payment. IF the debt had been amortized with payments equal in size to the total periodic payment, what would be the effective interest rate to the nears 0.01%?

***In Java language***The first programming project involves writing a program that computes the salaries for a collection of employees of different types. This program consists of four classes. 1. The first class is the Employee class, which contains the employee's name and monthly salary, which is specified in whole dollars. It should have three methods: a. A constructor that allows the name and monthly salary to be initialized. b. A method named annualSalary that returns the salary for a whole year. c. A toString method that returns a string containing the name and monthly salary, appropriately labeled. 2. The Employee class has two subclasses. The first is Salesman. It has an additional instance variable that contains the annual sales in whole dollars for that salesman. It should have the same three methods: a. A constructor that allows the name, monthly salary and annual sales to be initialized. b. An overridden method annualSalary that returns the salary for a whole year. The salary for a salesman consists of the base salary computed from the monthly salary plus a commission. The commission is computed as 2% of that salesman's annual sales. The maximum commission a salesman can earn is $20,000. c. An overridden toString method that returns a string containing the name, monthly salary and annual sales, appropriately labeled. 3. The second subclass is Executive. It has an additional instance variable that reflects the current stock price. It should have the same three methods: a. A constructor that allows the name, monthly salary and stock price to be initialized. b. An overridden method annualSalary that returns the salary for a whole year. The salary for an executive consists of the base salary computed from the monthly salary plus a bonus. The bonus is $30,000 if the current stock price is greater than $50 and nothing otherwise. c. An overridden toString method that returns a string containing the name, monthly salary and stock price, appropriately labeled. 4. Finally there should be a fourth class that contains the main method. It should read in employee information from a text file. Each line of the text file will represent the information for one employee for one year. An example of how the text file will look is shown below: 2014 Employee Smith,John 2000 2015 Salesman Jones,Bill 3000 100000 2014 Executive Bush,George 5000 55 The year is the first data element on the line. The file will contain employee information for only two years: 2014 and 2015. Next is the type of the employee followed by the employee name and the monthly salary. For salesmen, the final value is their annual sales and for executives the stock price. As the employees are read in, Employee objects of the appropriate type should be created and they should be stored in one of two arrays depending upon the year. You may assume that the file will contain no more than ten employee records for each year and that the data in the file will be formatted correctly. Once all the employee data is read in, a report should be displayed on the console for each of the two years. Each line of the report should contain all original data supplied for each employee together with 2 that employee's annual salary for the year. For each of the two years, an average of all salaries for all employees for that year should be computed and displayed. The google recommended Java style guide, provided as link in the week 2 content, should be used to format and document your code. Specifically, the following style guide attributes should be addressed: Header comments include filename, author, date and brief purpose of the program. In-line comments used to describe major functionality of the code. Meaningful variable names and prompts applied. Class names are written in UpperCamelCase. Variable names are written in lowerCamelCase. Constant names are in written in All Capitals. Braces use K&R style. In addition the following design constraints should be followed: Declare all instance variables private Avoid the duplication of code Test cases should be supplied in the form of table with columns indicating the input values, expected output, actual output and if the test case passed or failed. This table should contain 4 columns with appropriate labels and a row for each test case. Note that the actual output should be the actual results you receive when running your program and applying the input for the test record. Be sure to select enough different kinds of employees to completely test the program.

Write a Python program to read in the temperatures for ten consecutive days in Celsius and store them into an array. The entire array should then be displayed. Next each temperature in the array should be converted to Fahrenheit and the entire array should be again be displayed. The formula for converting Celsius to Fahrenheit is °F = (°C × 1.8) + 32. Finally, the number of cool, warm and hot days should be counted and the number of each type of days should be displayed. You should decide on the thresholds for determining whether a day is cool, warm or hot.
