l ZAIN IQ ? 3:39 PM @ O 69% H.W.1.jpg 1) Write a python program that reads three numbers from the keyboard and prints the sum. 2) Write a python program that reads three numbers from the keyboard and prints the average 3) Write a python program that reads three numbers from the keyboard and prints the minimum value 4) Write a python program that reads three numbers from the keyboard and prints the maximum value 5) Write a python program that reads a number from the keyboard and prints "Yes" if it's an ODD number and "No" otherwise. 6) Write a python program that reads a word from the keyboard and prints "Yes" if the length is greater than 5 and "No" otherwise 7) Solving quadratic equation program Let's consider the general formula of a quadratic equation : ax? + bx + c = 0 Example in the equation : x2 + 3x + 8 = 0 where a, b and c are real numbers and a # 0 a=1, b=3 and c=8 To solve the equation a discriminant D is calculated as : D = b2 – 4ac If D is less that 0 : there is no solution If D is equal to 0: there is one solution 2a If D is greater that 0: there is two solutions x1 and x2 -b+VD x1 = 2a -b - VD x2 = 2a Task : Write a program that reads from the keyboard three numbers a, b and c and prints the solutions(if exist) of the quadratic equation defined by the entered numbers. Indication : you can use the function sqrt() to calculate the square root of a number. Before using sqrt, you should import it from math library : from math import sqrt
