You will select one of the problems below and create a program that uses nested selections to solve the problem.Do not use Boolean operators. Write a program that reads three edges for a triangle and computes the perimeter if the input is valid. Otherwise, display that the input is invalid. The input is valid if the sum of every pair of two edges is greater than the remaining edge.
Written in Python The run time of a particular piece of Python code is normally distributed with mean 8 second and standard deviation 1.5 seconds. Write a piece of code to compute the probability that the code take between 7 and 11 seconds to run. Your code should print out the probability, rounded to 4 decimal places.
Generate a list of 10 random numbers with values between 1 and 20, and submit the first 10 numbers as an answer to this question. (Use any random number generator). For the purpose of using them in the next questions, call these numbers A, B, C, D, . . . J Convert Aπ/B into degrees. Find the result ofa. Degrees = (A × B × C) + 180 mod 180; this is the remainder after dividing (A × B × C) + 180 by 180 b. Convert Degrees into radians, and put the answer in π notation. Calculate the measurements of the acute angles of a right triangle whose sides measure A, B, C units. Build a matrix, M, of random numbers as follows: A B C D E F G H I What is MT? Find the inverse of M, showing the steps. What is the result of M * M−1? Let V = [A B C] and W = [ D E F]. In the textbook, the dot product V • W involves an angle, alpha (α).

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 Find the smallest value, and then subtract it from all three values, thus removing the gray.

Using Matlab. Monte Carlo methods are a class of computational methods that rely on repeated random sampling to compute their results. In this problem, you will use the Monte Carlo method to estimate the temperature at an arbitrary point in a uniform solid. Specifically, we will consider the solid object shown below. The temperatures of all surfaces are 500 des F with the exception of the two shaded surfaces, which are at 0 deg F. Inputs to the program should be: 1. The number of random walkers. 2. The (x,,2) coordinates of the point at which the temperature is to be estimated. 3. Plot interval (eg., you may want 1,000,000 random walkers in the simulation but may want to plot after every 10,000). Output from the program should be: 1. A graph of the estimated temperature, plotted according to the plot interval 2. Numerical value of the estimated temperature. USING MATLAB
Write a program that calculates the equivalent resistance of a circuit. n electrical resistors with resistance values R1, R2,.., Rn are said to be connected in parallel if the same voltage is applied across each. Their equivalent resistance Reg is related to the values R1, R2, ..., Rn by: 1 1 1 1 + +...+ R R R, R. "eq Write a program that prompts the user to enter the resistance of n resistors. The user should be prompted continuously by using a while loop until a zero or negative value is entered (the program should count the number of resistors n entered by the user and store the values in an array). Use another separate loop to print the resistance values entered by the user and the equivalent resistance Reg. Test your program with R1= 1 kn, R2= 2 kn, R3= 4 kQ and R4= 8 kQ.
Using Eclipse: Implement a program that directs a cashier how to give change. The program has two inputs: the amount due and the amount received from the customer. Display the dollars, quarters, dimes, nickels, and pennies that the customer should receive in return. In order to avoid roundoff errors, the program user should supply both amounts in pennies, for example 274 instead of 2.74. Use labels for each currency when you display.
Your relative, who goes to primary school and has just learned the multiplication table, asks you to constantly ask him. You wanted to gamify it. The computer will randomly scan in the multiplication table and the user will write the answer on the screen. There will be 10 questions in total and at the end the number of questions, the number of correct answers and the number of wrong answers will be printed on the screen. Also, write a program that will print if the percentage of success is below 80, it remained, and if it was above, it passed. (On C# ConsoleApp(.Net Framework)
A very known application in natural language processing is to extract information from a given text. In this lab, you will be able to extract some emotions (Sad and Happy) from a given string and calculate the score of each emotion. You will be given below the words that express sadness, anger, and happiness. For each word, you will be given weight as well, so that when you are calculating for example the score for sadness in the text (string), you can use this formula:
