Write a Matlab program in a script file that finds and displays all the numbers between 700 and 2999, whose product of digits is 6 times the sum of the digits (e.g. 2864 since 2*8*6*4 = 6(2+8+6+4)). You may use a loop in the script. For extra credit, print out also the number of times that the product and sum were the same! (5 pts)

Write a program that creates the multi-panel plot shown below, for Planck curves at 4 different temperatures Planck Curves Use embedded noninteractive plotting and set the figure size to be 10x5 inches. • You may write your program in a single cell, or break it over multiple cells. Use a logarithmic x axes, and the logspace() function for generating the axes values. You will have to be careful with units on this one. For 50% extra credit have your program use a loop over the four axes, with all the plotting code contained within the loop (except for any subplot adjustments). 0.030 12 300K 1000K 0.025 10 0.020 FBBX (Wm-nm-1) FBBA (Wm-2nm-¹) 0.015 10 0.010 0.005 2 0.000 A (nm) λ (nm) 100000 3000 3000K 6000K 2500 80000 2000 60000 FBBA (Wm-2nm-¹) FBBX (Wm-2nm-1) 1500 40000 1000 20000 500 0 101 102 0 101 103 104 105 106 102 103 104 105 106 X (nm) λ (nm) python language
You are writing an inventory system for a library. This program will allow the user to enter a book, remove a book, and find a book. The book titles will be stored in a dictionary. Each key in the dictionary is a book’s title, and each value is the number of copies currently in stock. In a continuous loop, give the user the option to add a book, remove a book, find a book, and quit. If the user chooses to add a book, call a function named add_book. This function should ask for a book title and how many copies the user is adding. If the title is not yet in the dictionary, add a new key/value pair to the dictionary with the key being the book title and the value being the amount the user is adding. If the title is already in the dictionary, update its value to include the copies the user is adding. If the user chooses to find a book, call a function named find_book which asks the user for a book title. If the book’s title exists in the dictionary, print out how many copies of it…

Your program must contain at least the following functions: a function called GetData to read and store data into two arrays, a function called Average that is used to calculate the average test score and grade, and a function called PrintResults to output the results. The student names should be to the left with a width of 10 columns. The test scores should be to the right with a width of 8 columns. Have your program also output the class average on a line…
A teacher has asked all her students to line up single ﬁle according to their ﬁrst name. For example, in one class Amy will be at the front of the line and Yolanda will be at the end. Write a program that prompts the user to enter a number between 1 and 25 for the number of students in the class, then loops to read in that many names. Once all the names have been read in it reports which student would be at the front of the line and which one would be at the end of the line. You may assume that no two students have the same name.
Write a program using while loop and for loops to print first 50 prime numbers in 5 lines, each line containing 10 numbers. 1. Create a program called CountCharacters.java. 2. At the top of your java file add the following documentation comments. Replace the italicized text with the appropriate content. /** @author Your Name CS 110 Section 012 Lab 9 Final Today's Date 3. Import the Scanner class and ask user to enter a line. Implement the while loop so that the user can input any number of lines and one line at a time. To stop entering lines, the user can write "quit. (Hint: Use the string method <str>.equals() in the while condition to stop the while loop OR a break keyword). 4. Implement the for loop inside the while loop to iterate through the line one character at a time to count and output the number of blank spaces, alphabetic characters, digit characters, and other characters in all the lines. You need to use different methods of character class like charAt(), isDigit(),…
Using a csv file attached (https://file.io/NMvbdnv4E3r0), Create a program on python that use the csv file. The program should accept a user's input of a compound. It should output the molar mass (in 2 decimal places only) of the compound.by using the csv file to compute for the atomic mass at name of the elements. Furthermore, if the "elements involved" are wrong an invallid message should be outputted and only existing chemical symbols are the output. The same goes for wrong input of the "number of atoms" wherein a wrong an invallid message should be outputted and only integers are to be inputted by the user. Program should look like this: Enter compound: C6H12O6 Enter elements involved: C,H,O Enter no. of Carbon atoms: AA Enter no. of Hydrogen atoms: 12 Enter no. of Oxygen atoms: 6 Wrong input of number of atoms! Try again. or Enter compound: C6H12O6 Enter elements involved: C,H,O Enter no. of Carbon atoms: 6 Enter no. of Hydrogen atoms: 12 Enter no. of Oxygen atoms: 6…
Write a program that computes and displays the five set of products of each three random numbers between 1 and 20 using only for loops (Don’t use Arrays). Here is a sample run: The Product 1: of 2, 10, 8 is 180 The Product 2: of 11, 3, 20 is 660 The Product 3: of 5, 12, 8 is 480 The Product 4: of 3, 5, 7 is 105 The Product 5: of 12, 11, 18 is 2376
Here is the assignment Write a program that prints the multiplication table but inserts a randomly generated incorrect value between 1 and 50 into a cell whose row and column are randomly selected. Make sure the program does insert an incorrect value. For example, if row and column of 3 and 4 are randomly selected, keep generating a random number to print for that location until it's not the right value of 12. Then, ask the user to tell where in the table the incorrect number is located by entering the row and column of the incorrect number. Print whether the user was right or not. If he or she was right, ask for and read the correct value; if not, the program must give the correct location and the correct number. My main issue: is how to set up the multiplication table? I've only learned the basics in C++ (loops and if statements).
Using Python build your own song remixing solution. As an example: given the following American children’s song (this is ONE of the 3 songs I’m giving you in the starter code that includes the data you'll use for your program) Starter file: music.py (data file for my songs and playlist) here below; SONG = ['old macdonald had a farm - ee-i-ee-i-o.', 'and on that farm he had a cow - ee-i-ee-i-o.', 'with a moo moo here and a moo moo there', 'here a moo - there a moo - everywhere a moo moo', 'old macdonald had a farm - ee-i-ee-i-o.' ] Do This: Create a solution that allows users to: Load a new song from our playlist When requested, show the title of the song you’re currently remixing Continue the above operations on demand, until the user explicitly quits your program. Note that there is punctuation in some of the songs we've given you. When you remix a song, you should remove the punctuation (see the example reverse below). If you are unable to perform…
Write a program that reads in from a file a starting month name, an ending month name, and then the monthly rainfall for each month during that period. As it does this, it should sum the rainfall amounts and then report the total rainfall and average rainfall for the period. For example, the output might look like this: During the months of March-June, the total rainfall was 7.32 inches and the average monthly rainfall was 1.83 inches. Data for the program can be found in the rainfall.txt file located in the Chapter 5 º programs folder on the book's companion website. Hint: After reading in the month names, you will need to read in rain amounts until the EOF is reached and count how many pieces of rain data you read in.
Download the text file, Random.txt, from the demo file folder on Canvas. This file contains a long list of random numbers. Copy the file to your hard drive (where the working directory of the IDE you use). Write a program that opens the file, reads all the numbers from the file, and calculates the following: 1. The number of numbers in the file 2. The sum of all the numbers in the file (a running total) 3. The average of all the numbers in the file Requirements: The program should display all numbers found in the file, and every twenty numbers in one line. Summarize the number of numbers found in the file, the sum of the numbers, and the average of the numbers in a table format. The average should be displayed in 2-digit in decimal. I mostly need help with the second part of requirements (1) It is C++
