Suppose you are a computer salesman and your income depend on the total sales and commissions earned for the computers that you sell. Commission rates vary depending on how many units you sold (see chart below). Your income equals to the total sales plus the commission where the commission equals to total sales times the commission rate. That is, commission = total sales * commission rate and income = total sales + commission. Total Sales Commission rate % Less than 200 sold 8% (totalsales < 200) Greater or equal to 200 sold 10% (totalsales >=200 & totalsales <400) Greater than to 400 sold 12% (if (totalsales >= 400) Use Multiway if, else if (use as many you need) and else correctly Review slides 3-CH-2 Slide 4 and 8 Write the code correctly as show in the chapter slides.

We want to develop a game where the user should guess a secret number. The game asks the user to input a number and tells how close it is to the secret random number that the game generates. Complete the main() function that implements this game by calling the get_user_input(), generate_secret(), and display_result(user_input, secret) functions that you will develop as follows: • Complete the get_user_input() function so that it prompts the user to enter a whole number between 1 and 20 (inclusive) and returns the number that the user enters. • Complete the generate_secret() function so that it generates and returns a random number between 1 and 20 (inclusive). Complete the display_result(user_input, secret) function that takes the two parameters that correspond to the user input and the secret. It should then print the absolute difference between these two numbers. For example: Test Input Result random.seed (10) 5 random.seed(50) 6 Enter a number from 1 to 2015 You entered 5. The…

Please note that on the last line of the code, we need to print out the 'and" with the smallest and the largest number for min and max functions in order to maximize our credit with the zyBooks lab assignment for 3.9. Code Hints: smallestnum = min(usernumbers) #The smallest number is printed out - for example 5, 10, 15 - 5 would be printed out largestnum = max(usernumbers) #The largest number is printed out - for example 5, 10, 15 - 15 would be printed out Write a program that reads a list of integers into a list as long as the integers are greater than zero, then outputs the list values and the smallest and largest integers in the list using min and max built-in functions .

1. ponder_orb_density One of the most important questions to ponder about an orb is: what is the density of this orb? Here we will assume a spherical orb and calculate (ponder) its density as a function of its radius and mass. Recall that density is mass/volume, and recall (or look up) that the volume of a sphere is 4/3 * pi * r3. Sample calls should look like: >>> ponder_orb_density(1, 1)0.23873241463784303>>> ponder_orb_density(1, 10)2.3873241463784303>>> ponder_orb_density(2.5, 200)3.0557749073643907
For example, the number 35190 can be cut between 351 and 90 digits, from 3 + 5 + 1 = 9 and 9 + 0 = 9. On the other hand, the number 555 has no place to rest (you must divide between digits). Create a retrieval function if the number has a breakpoint, and is false if not. Examples break_point (159780) - true break_point (112) - true break_point (1034) - true break_point (10) lie break_point (343) – lie
