Exercise II Write a program that finds the positive integer solutions of the following equation ax³ + bx² + cx' + d = 0. The user enters the values of coefficients a, b, c and d. The program should test each integer starting from -50 to 50, and each time the equation is equal to zero, it prints its value as well as "is a solution". At the end, it displays the total number of positive integers found. Note that if the equation has more than one solution, the plural word "solutions" is used in the output. Sample run 1: Enter the coefficient of a, b, c, d: 1 -8.5 21 -13.5 1 is a solution 3 is a solution The equation has 2 integers as solutions Sample run 2: Enter the coefficient of a, b, c, d: 6 48 103.5 67.5 The equation has no integer solutions Sample run 3: Enter the coefficient of a, b, c, d: 1 -1 -12 0 4 is a solution The equation has 1 integer solution

Given a positive integer n, the following rules will always create a sequence that ends with 1, called the hailstone sequence: If n is even, divide it by 2 If n is odd, multiply it by 3 and add 1 (i.e. 3n +1) Continue until n is 1 Write a program that reads an integer as input and prints the hailstone sequence starting with the integer entered. Format the output so that ten integers, each separated by a tab character (\t), are printed per line. The output format can be achieved as follows:print(n, end='\t') Ex: If the input is: 25 the output is: 25 76 38 19 58 29 88 44 22 11 34 17 52 26 13 40 20 10 5 16 8 4 2 1 this is what i have n = int(input())count = 1while n != 1: if count%10==0: print(n,'\t') else: print(n, end='\t') if n%2==0: n = int(n/2) else: n = int(n*3 + 1) count = count + 1 print(n) the output is correct but theres whitespaces that arnt needed
7- Write a program to input number of 3 digits and check whether it is Armstrong Number or Not. Hint: to check Armstrong number, we have to calculate sum of each digit's cube and then compare number is equal to Sum or not. If Number equal to Sum of digit's cube then Number will be an Armstrong Number otherwise not. Examplel: 153 is an Armstrong number: here 153 = (1*1*1) + (5*5*5) + (3*3*3). Example2: 371 is an Armstrong number: here 371 (3*3*3) + (7*7*7) + (1*1*1). Example2: 322 is not Armstrong number: here 322 = (3*3*3) + (2*2*2) + (2*2*2).

python Write a program that prompts the user to enter the number of study hours of a student and the average of the student. Then the program is checking the following:- If the average of the student is greater than 4 and the number of hours is less than 26, then the program should display "You have a chance".- Otherwise, the program should display "You do not have a chance".
Prime factors of an integer \( n \) are a set of prime numbers that can be multiplied together to obtain \( n \). Write a proHide Transcribed Text Prime factors of an integernare a set of prime numbers that can be multiplied together to obtainn. Write a program that asks the user to enter a number and displays the prime factors ordered from smallest to largest. If the number entered by the user is less than 2 then there are no prime factors and the message "No prime factors" should be displayed. The following algorithm can be used to discover the prime factors: - initialize factor to 2 - while factor is less than or equal tondo: ifnis evenly divisible by factor then - conclude that factor is a factor ofn- dividenby factor using floor division else: - increase factor by 1 Adapt the algorithm so it can be used to print out the prime factors of a number. Notes: - You can assume that the number entered by the user will be an integer number. - The output must be in the format shown in the…
4) Roll the dice 2 Make a program that tests the probability of a certain score when rolling x dice. The user should be able to choose to roll eg 4 dice and test the probability of a selected score eg 11. The program should then do a number of simulations and answer how big the probability is for the selected score with as many dice selected. There must be error checks so that you cannot enter incorrect sums, for example, it is not possible to get the sum 3 if you roll 4 dice. TarningsKast2 How many dices do you want to throw? 11 Which number do you want the probability for? The probability the get the number 11 with 4 dices is 7.19% Calculate

A company of 20 employees wants to find the employee who made the highest commission so he/she can be paid a 10% bonus of the commission he/she earned for that month. The commission an employee makes is calculated by multiplying the sales amount by the commission rate. The commission rates are shown below: Sales Amount Commission Less Than 40000 No commission 40000 to 80000 inclusive 5% Greater than 80000 10% Write a program to: Prompt the user for each employee’s id (an integer value) and the sales amount For each employee, display the commission earned Display the total commission earned by all the employees Display the average commission earned by an employee Display the employee id, the commission and the bonus paid to the employee with the highest commission Must be written in c++, no arrays to be used, only use iostream library
