Question 4: Write a program that receives 8 positive numbers from the user. Make sure you have 8 positive number at the end. Each time the user enters a negative or string, print a message. 1. Display, the average of 8 positive numbers collected, the sum of all positive odd numbers and the maximum of the 8 positive numbers. 2. Determines how many of them are prime, composite or neither prime or composite and prints the message. Do not use Python's internal functions for sum, average and maximum. Question 5: Write a Python program that accepts an integer (b) 1. Computes the value of 2b+3bb+1.5bbb. 2. Compute sum of the first b positive integers (if the number is negative convert it to positive). Question 6: Write a program that takes as input two points: (x1,y1) and (x2,y2) - float or integer only. Finally, the user is prompted for a third point (x3,y3). The program should find the distance between the points (x1,y1) and (x3,y3) and the points (x2,y2) and (x3,y3). At the end of each run, the user should be prompted to ask whether then want to continue
