TASK 1 – Work out the cost. The cost of the trip for each student is a share of the cost of a coach plus the cost of entry to the theme park.
The total cost of the coach will be $550. The entry cost to the park is $30 for each student. The national park gives one free ticket for every ten that are bought, which must be taken into consideration.
Set up a program that:

• stores the cost of the coach
• stores the cost of an entry ticket
• inputs the estimated number of students taking part, this must be validated on entry and an
unsuitable entry rejected
• calculates and outputs the recommended cost per student to ensure the trip does not make a loss.

Write an algorithm to complete Task 1, using either pseudocode, programming statements or a
flowchart. [5]

Write a program that uses a widgetviewer object to do the following: generate two random integers between 1 and 9 (inclusive). name one of them x, the other y. display them to the user using jlabel objects. create a jlabel object displaying the text "enter an operation number." create a jtextfield for the user's input. create a jbutton displaying the text "press here when you've entered your operation." use addandwait to add it to the widgetviewer object. when the user clicks the jbutton, evaluate operation in the following order to determine the one and only mathematical operation to perform on x and y. use a jlabel to display the result. if operation is between 1 and 10 inclusive, add x and y. if operation is evenly divisible by 4, subtract y from x. if operation is evenly divisible by 5, use integer division to divide y into x. if operation is an even number, use floating point division to divide y into x. if none of the other tests on operation apply, multiply x and y. note: operation can be negative or zero.

Using least squares fitting, you are to fit the data sets to the following models and solve for the parameters ai , where i is the index of the parameter. the input/output data for the systems are linked in the bblearn site. for each of the systems use matlab to plot the supplied data vs. the model fit on one plot. include your code in the solutions. (a) linear fit "lineardata. mat" y=a1x^3 + a2x^2 + a3x + a4 (b) plant fit "plantdata. mat g(s) = a1/(s + a2)
