Summary: Given integer values for red, green, and blue, subtract the gray from each value.
Computers represent color by combining the sub-colors red, green, and blue (rgb). Each sub-color's value can range from 0 to 255. Thus (255, 0, 0) is bright red, (130, 0, 130) is a medium purple, (0, 0, 0) is black, (255, 255, 255) is white, and (40, 40, 40) is a dark gray. (130, 50, 130) is a faded purple, due to the (50, 50, 50) gray part. (In other words, equal amounts of red, green, blue yield gray).
Given values for red, green, and blue, remove the gray part.
Ex: If the input is:
130 50 130
the output is:
80 0 80

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?

- Part 4: For circle, square and annulus write a program to find the area, perimeter (or circumference) for a range of parametric values given by the user and plot the corresponding shapes in the range given. User needs to identify lower and upper values of each parameter. The identified range for the parameters should be then divided into 10 monotonic steps inside your program. Accordingly, you need to calculate the values and plot the shapes corresponding to all 10 values in the range identified by the user. The program should plot the geometries in the first quadrant.arrow_forwardPlease help answer these two questions in Python.

The exact rule is: • Years divisible by 4 are leap years • except if they are also divisible by 100 and then they are not leap years (so 1900 was not a leap year), • unless they are also divisible by 400 and then they ARE leap years (so 2000 was a leap year). Part 1) Write a function in Python that takes as input a number, the year, and determines if it is a leap year or not. The function should return True if it is a leap year and False otherwise. Part 2) Write a main function to test out your leap year function on a few different illustrative inputs.arrow_forward1) 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
- How to attempt? Question : The Card Game One day, Fred and his N friends were playing a card game in which each player throws a card with a number written on it. The cards are such that a number X is written on front of the card, and the negative of that number is written on the back side of the card. This game has the following rules: - Each of the N players is asked to throw a card. After all the N cards are thrown, Fred has to flip one or more cards in consecutive order, only once. Your task is to help Fred flip the cards in such a way that the sum of the numbers, on front face of the cards, is the maximum.arrow_forwardC Programming Language (Code With C Programming Language) Problem Title : Visible Trees There is a legend about a magical park with N × N trees. The trees are positioned in a square grid with N rows (numbered from 1 to N from north to south) and N columns (numbered from 1 to N from west to east). The height (in metres) of each tree is an integer between 1 and N × N, inclusive. Magically, the height of all trees is unique. Bunga is standing on the northmost point of the park and wants to count the number of visible trees for each Column. Similarly, Lestari is standing on the westmost point of the park and wants to count the number of visible trees for each Row. A tree X is visible if all other trees in front of the tree X are shorter than the tree X. For example, let N = 3 and the height (in metres) of the trees are as follows6 1 87 5 32 9 4 On the first column, Bunga can see two trees, as the tree on the third row is obstructed by the other trees.

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.

- Problem Description: The bird of paradise called the Helipixsal is renowned for its magnificent tail feathers which range in number from five to nine ornate feathers each of a different length. Their "magnificence" is quantified by the rather simple process of counting the exact number of tail feathers and multiplying this by the difference in the length of the minimum and maximum lengths of tail feather. You are to write a simple program that will allow the user to enter the length of each tail feather individually and keep on entering feathers until a -1 is entered. The program will then return the quantified "magnificence" factor.arrow_forwardQUESTION 5 This is a MULTIPLE ANSWER question, which means you are able to select one or more answers as being correct. Note that this does not necessarily mean that there are multiple correct answers. In any case, select all the answers you believe are correct. (NB: There are no part marks awarded for multiple answer questions.) Consider the following Python code, where the variables level and threshold have integer values: alarm = 3 if level = threshold: if level < 100: alarm = 1 alarm = 2 What initial values for variables level and threshold guarantee that variable alarm ends up with the value of 2 after the code has executed? When level is 200 and threshold is 99 When level is 4 and threshold is 5 ☐ When level is 200 and threshold is 100 When level is 400 and threshold is 300 When level is 5 and threshold is 4 When level is 3 and threshold is 4 When level is 1 and threshold is 2 O When level is 10 and threshold is 10arrow_forwardMATLAB The Mach number is a critical quantity in aerodynamics. It is the ratio of the speed of an object (e.g., an aircraft) to the speed of sound. If the Mach number is less than 1, the flow is subsonic; if the Mach number is between (0.8-1.2), the flow is transonic; if the Mach number is equal to 1, the flow is sonic; if the Mach number is between (1.2 and 5), the flow is supersonic; if the Mach number is greater than 5, the flow is hypersonic. Write a script that will prompt the user for the speed of an aircraft and the speed of sound at the aircraft's current altitude and will print whether the condition is subsonic, transonic, sonic, supersonic or hypersonic.arrow_forward
