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?

(Pick 5 Lotto) Write a program to simulate a pick-5 lottery game. Your program should generate and store 5 distinct numbers between 1 and 9 (inclusive) into an array. The program prompts the user to enter five distinctbetween 1 and 9 and stores the number into another array. The programthen compares and determines whether the two arrays are identical. If thetwo arrays are identical, then the user wins the game; otherwise the program outputs the number of matching digits and their position in the array.Your program must contain a function that randomly generates thepick-5 lottery numbers.

- please quickly thanks !! use Pythonarrow_forward(C Language) A photographer is organizing a photo collection about the national parks in the US and would like to annotate the information about each of the photos into a separate set of files. Write a program that reads the name of a text file containing a list of photo file names. The program then reads the photo file names from the text file, replaces the "_photo.jpg" portion of the file names with "_info.txt", and outputs the modified file names. Assume the unchanged portion of the photo file names contains only letters and numbers, and the text file stores one photo file name per line. If the text file is empty, the program produces no output. Assume also the maximum number of characters of all file names is 100.arrow_forwardPlease help with simple java code i/oarrow_forward

Test Scores File: test_scores.py Write pseudocode for the main() part of a program that asks the user to enter 4 test scores between 0 and 100, then displays a JCU grade for each score and also the average test score. When you have written the pseudocode for main, implement your solution in Python code and test it with a range of meaningful data. Remember that we've done the JCU grades question before, so copy your function from that practical code file. Sample Output Score: 3 Score: 50.5 Score: 66 Score: 100 Score 3.0, which is N Score 50.5, which is P Score 66.0, which is C Score 100.0, which is HD The average score was 54.875 Enhancements When you have that working...

You must have seen two types of images: color andgrayscale. A color image pixel has three colors: Red, Green, and Blue, but a grayscale imagepixel has only one color: Gray. Regardless of the image type, a color always has an 8-bitinteger value (0-255) associated with it. You need to implement a program that can input,create, update and display the images (matrices). It should be able to compute their negatives(matrices) as well. NOTE: You need to generalize the computation of negatives, for we onlyneed to subtract the color values from 255, regardless of the image type.arrow_forward
