The

company wants to use a computerised system for selling their tyres. There are 2 types of

tyres in stock, namely those for luxury vehicles and those for construction vehicles.

4

Construction vehicle tyres cost twice the price of luxury vehicle tyres, and the prices

depend on the wheel size according to the following price list for luxury vehicles:

Wheel Size Price/Unit measurement ($)

Less than 10 Inches 3.50

10- 15 Inches 4.00

Greater than 15 inches 6.00

You are required to create a python program that implements the program according to

the following guidelines:

a) Create a class called Home, which contains a function called Details for receiving the

values of the type of vehicle, the size of the tyres and the number of tyres for the

vehicle.

b) Create a class called Construction which contains:

i) A constructor

ii) A function called Calc for doing relevant calculations for calculating the total price

of the tyres purchased for construction vehicles.

PRACTICAL: Question 6 (Marks: 10)

Create a PL/SQL query to display the customer name and total amount spent by each customer. In your solution determine the customer rating. If the total amount spent is greater than or equal to R 1000, the customer receives a star rating, otherwise no star rating applies.

Sample Output

FIRST NAME: Patrick

SURNAME: Smith

AMOUNT: R 700

----------------------------------------------------

FIRST NAME: Steven

SURNAME: Hewson

AMOUNT: R 570

----------------------------------------------------

FIRST NAME: Barry

SURNAME: Goodwin

AMOUNT: R 2500 (***)

Assume a file named 

Random.txt

exists, and contains a list of random numbers. Write a program that opens the file, reads all the numbers from the file, and calculates the following:

• The number of numbers in the file
• The sum of all the numbers in the file (a running total)
• The average of all the numbers in the file

The program should display the number of numbers found in the file, the sum of the numbers, and the average of the numbers.

Output Labels:

Print each of the above quantities on a line by itself, preceded by the following (respective) strings: "

Number of numbers: 

", "

Sum of the numbers: 

", and "

Average of the numbers: 

".

Sample Run

Number of numbers: 20

Sum of the numbers: 210

Average of the numbers: 10.5 

Write the pseudocode and flowchart for a vending machine

Create a windows desktop application which can be used by a local gardening service to determine the amount due by customers.

Your program should request the user to input the approximate length and breadth of the lawn, and whether cleaning the flower beds are included. Your program should then calculate and display the amount due, which is R8 per square meter of lawn, and a fixed cost of R60 if the flower beds needs to be cleaned.

1. Write a program that generates a random number between 0 to 10. Use the following statements below for generating random number and the class Random from the package java.util:Random rand = new Random();int num = rand.nextInt(10);2. Display the generated random number with text: "The generated random number between 0 to 10 is: ".3. Name the class as RandomNumber and save the file.4. Compile and execute the program using the command prompt (cmd). If you do not have cmd, run it in JDoodle.
