Write a matlab program in a script file that calculates the average and the standard deviation of a list of grades as well as the number of grades on the list. the program asks the user (input command) to enter the grades as elements of a vector. the program then calculates the required quantities using matlabs built-in functions length, mean, and std. the results are displayed in the command window in the following format: "there are xx grades." where xx is the numerical value. "the average grade is xx." where xx is the numerical value rounded to the nearest tenth. "the standard deviation is xx." where xx is the numerical value rounded to the nearest tenth. execute the program and enter the following grades: 93, 77, 51, 62, 99, 41, 82, 77, 71, 68, 100, 46, 78, 80, and 83

Design a pos circuit that displays the letters a through j on a seven-segment indicator. the circuit has four inputs w, x, y, and z which represent the last 4 bits of the uppercase ascii code for the letter to be displayed. thus, if wxyz = 0001 then "a" will be displayed. (any answer with 22 or fewer gates and inverters, not counting any for the inputs, is acceptable)

1. ask the user how many questions are in the quiz. 2. ask the user to enter the key (that is, the correct answers). there should be one answer for each question in the quiz, and each answer should be an integer. e.g., 34 7 13 100 81 3 9 10 321 12 might be the key for a 10-question quiz. you will need to store the key in an array. 3. ask the user to enter the answers for the quiz to be graded. there needs to be one answer for each question. note that these answers do not need to be stored; each answer can simply be compared to the key as it is entered. 4. when the user has entered all of the answers to be graded, print the number correct and the percent correct. 5. add a loop so that the user can grade any number of quizzes with a single key. after the results have been printed for each quiz, ask "grade another quiz? (y/n)." note: you only have one array (the key). you are not creating a new key for each set of quiz answers.
