Apply clustering to "Wholesale customers Data Set" and see if you can distinguish between regions. NOTE: the clustering should exclude the region column.

Create a graphical spell checker program that The File menu has the three items shown. On Open, the program reads a text file (!) with the current directory set to the directory where your program is located. Save saves the current text in the window to the file selected over a dialog and The Edit menu has one menu item: Spell Check.

For a perceptron algorithm with a fixed learning rate(r), prove or disprove that if the classes are not linearly separable, it may not converge. Can you modify the learning rate(r) so that the iterations converge in expectation? Explain.

Write a c program that prints the final sum of all values from 1 to n only when n is a positive value. The program is to print "Poor!" when the final sum is less than 70, print "Good" when the sum is between 71 and 90. or "Great!" when the sum is 91 or better.

Plot the hyperbolic paraboloid given by: z = x**2/a**2 - y**2/b**2. You may use any non-negative integer values for a and b.

The citizens of Javaland require a program that calculates the personal income tax owed by

each taxpayer.

Write the code for a class method

calculateTaxableIncome

that accepts the following 5

inputs:



General Income



Investment Income



Other Income



Regular Deductions



Other Deductions

The method calculates the amount of a citizen’s taxable income. Taxable income is obtained

by summing all income and subtracting all deductions. Note that only 50% of Other

Deductions are tax deductible.

The signature for this method is:

public static double calculateTaxableIncome(double generalIncome, double

investmentIncome, double otherIncome, double regularDeductions,

double otherDeductions)

Note that all calculated monetary values should be rounded to 2 decimal places.

Write the code for a class method

calculateIncomeTax

that accepts the following input:

Taxable Income. The method calculates the amount of income tax due to the Government of

Javaland based on a citizen’s calculated taxable income. Income tax is calculated as a

percentage of taxable income based on the following rules:

10% on the first $20,000 of taxable income

12% on the next $20,000 of taxable income

15% on the next $20,000 of taxable income

20% on all remaining taxable income

The signature for this method is:

public static double calculateIncomeTax(double taxableIncome)

Interger Programming and Nonlinear Programing are two important extensions of the basic Simplex Linear Programing model. How does each differ from Simplex in theory and practice? How does Solver adjust for these two extensions? What about Rosenbrock’s method, cutting plane procedure, and interior point methods?

PUT IN JAVA PROGRAMMING

The Rectangle class: Design a class named Rectangle to represent a rectangle. The class contains:
• Two double data fields named width and height that specify the width and height of a rectangle. The default values are 1 for both width and height.
• A no-arg (default) constructor that creates a default rectangle.
• A constructor that creates a rectangle with the specified width and height.
• A method named findArea() that finds the area of this rectangle.
• A method named findPerimeter() that finds the perimeter of this rectangle.
• Create a client (test) class (program) to test and use your Rectangle class. In the client program, you need to create objects of the Rectangle type and use those objects to perform some meaningful and valid rectangle operations (finding area and perimeter). The test/client class should display all results
