CPU Usage
We have the hourly average CPU usage for a worker's computer over the course of a week. Each row of data represents a day of the week starting with Monday. Each column of data is an hour in the day starting with 0 being midnight.
Create a chart that shows the CPU usage over the week. You should be able to answer the following questions using the chart:
When does the worker typically take lunch?
Did the worker do work on the weekend?
On which weekday did the worker start working on their computer at the latest hour?

Problem Description:
In the Whimsical Library, each book is enchanted with a magical code to ensure the
protection of knowledge. The validation process for these magical codes involves a
combination of mathematical spells.
The validation process is described as follows:
Take the sum of the digits at odd positions from left to right.
Take the sum of the squared digits at even positions from left to right.
If the absolute difference between the results from step 1 and step 2 is a prime
number, the book code is considered valid; otherwise, it is invalid.
Example 1:
Consider the magical book code 86420137.
Step 1. Take the sum of the digits at odd positions from left to right.
8+4+0+3=15
Step 2. Take the sum of the squared digits at even positions from left to right.
6^2+2^2+1^2+7^2=36+4+1+49 = 90
Step 3. If the absolute difference between the results from step 1 and step 2 is a prime
number.
115-901 = 75 (not a prime number)
Book code 86420137 is invalid.
Example 2:
Now, let's examine the…
Parking Charges) A parking garage charges a $2.00 minimum fee to park for up to threehours and an additional $0.50 per hour for each hour or part thereof over three hours. The maximumcharge for any given 24-hour period is $10.00. Assume that no car parks for longer than 24 hoursat a time. Write a program that will calculate and print the parking charges for each of three customers who parked their cars in this garage yesterday. You should enter the hours parked for eachcustomer. Your program should print the results in a tabular format, and should calculate and printthe total of yesterday's receipts. The program should use the function calculateCharges to determine the charge for each customer. Your outputs should appear in the following format:Car Hours Charge1 1.5 2.002 4.0 2.503 24.0 10.00TOTAL 29.5 14.50

As part of her evaluation, she asks members for the number of fat grams and carbohydrate grams that they consumed in a day. Then, she calculates the number of calories that result from the fat, using the following formula: calories from fat = fat grams x 9. Next, she calculates the number of calories that result from the carbohydrates, using the following formula: calories from carbs = carb grams x 4. Write a program that will make these calculations. Your program should use two separate functions to calculate fat and carb calories.

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.

- 1) Simple Calculator: In Python, implement a simple calculator that does the following operations: summation, subtraction, multiplication, division, sqrt, power, natural log and abs. a) Follow the instructions below: To work with the calculator, the user is asked to enter the first number, then the operation, and finally, a second number if required. Your code has to recognize the need for the second number and ask for it if required. After performing one operation, the calculator prints the output of the operation. After performing one operation, the calculator must not exit. It has to start again for the next operation. The calculator will be closed if the user writes 'e' as any input. Use functions to perform the operations and the appropriate conditions to prevent common errors such as entering characters as one of the numbers etc. b) Run your code and provide the results for at least one example per operation. - -arrow_forward## MP (Machine Problem) Details The bulls and cows game is a code-breaking game designed for two or more players. Each player chooses a secret code of 4 digits from 0 – 9. The digits must be all different. The goal of the game is for each player to guess the other player's secret code. The players in turn present their guesses to the opponents. The opponents respond by telling the players: 1. The number of bulls, i.e. the number of matching digits in their right positions, and 2. The number of cows, i.e. the number of matching digits but in different positions. ### Requirements The main goal of this assignment is to develop the bulls and cows game that allows a single player to play interactively against the computer. The game stores two secret codes, one from the player and one from the computer. The player and the computer will try to guess each other’s secret code. Both the player and the computer only have seven attempts for guessing the secret code.

Maybe you're hosting a party with a lot of guests! In these circumstances, it's better to make preparations in advance.So, we will ask a user to enter the desired amount of coffee, in cups. Given this, you can adjust the program by calculating how much water, coffee, and milk are necessary to make the specified amount of coffee.Of course, all this coffee is not needed right now, so at this stage, the coffee machine doesn't actually make any coffee yet. ObjectivesLet's break the task into several steps:First, read the numbers of coffee drinks from the input.Figure out how much of each ingredient the machine will need. Note that one cup of coffee made on this coffee machine contains 200 ml of water, 50 ml of milk, and 15 g of coffee beans.Output the required ingredient amounts back to the user.
