1- Each Student Creates the F1 & F2 Equation With Their Own Number For example: Student Number: 249176126876 FI=2X^5+4X^4+9X^3+1X^2+7X^1+6X^0 F2 =1X^5+2X^4+6X^3+8X^2+7X^1+6X^0 For two equations: 1. Perform addition and the result (T) is variable. 2. Subtract and the result (C) is variable. 3. If: X = linspace (-5, 5, 100), plot the relationship between X and T. 4. Do the multiplication and the result (V) is a variable. 5. Divide and the result (A, B) is variable. 6. Introduce (T/F1) as a transfer function in MATLAB. 2- Program the desired operation using MATLAB commands for the given transfer function. write as: H1/H2=2X^5+9X^3+6/X^6+2X^4+8X^2+7X For X=linspace (1, 5, 10), if H1>H2, Draw the relationship between X and H1 or? Draw the relationship between X and H2 Note: Student number to be used in the solution; 207106106015 To be solved using the Matlap program
Declare an array that represents 100 students. Assign the examscores between 0 and 100 randomly into this array. Write amethod and display that assigns letter grade equivalents of theexam scores to a second array. Display the number ofunsuccessful students.The grade scala is as follows:100 – 90 : A89 – 80 : B79 – 70 : C69 – 60 : D59 – 0 : F (unsuccessful) (Write in java)
CODE IN JAVA design a program that grades arithmetic quizzes as follows: (Use the below startup code for Quizzes.java and provide code as indicated by the comments) 1. Ask the user how many questions are in the quiz. 2. Use a for loop to load the array. 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. They can be entered on a single line, e.g., 34, 7, 13, 100, 8 might be the key for a 5-question quiz. You will need to store the key in an array called "key". 3. Ask the user to enter the student's answers for the quiz to be graded. There needs to be one answer for each question. Note that each answer can simply be compared to the key as it is entered. If the answer is correct, add 1 to a correct answer counter. need this in a separate for loop from the loop used to load the array. 4. When the user has entered all of the answers to be graded, print the number correct…
*in java* Array testGrades contains NUM_VALS test scores. Write a for loop that sets sumExtra to the total extra credit received. Full credit is 100, so anything over 100 is extra credit. Ex: If testGrades = {101, 83, 107, 90}, then sumExtra = 8, because 1 + 0 + 7 + 0 is 8. import java.util.Scanner; public class SumOfExcess {public static void main (String [] args) {Scanner scnr = new Scanner(System.in);final int NUM_VALS = 4;int[] testGrades = new int[NUM_VALS];int i;int sumExtra = -9999; // Assign sumExtra with 0 before your for loop for (i = 0; i < testGrades.length; ++i) {testGrades[i] = scnr.nextInt();} /* Your solution goes here */ System.out.println("sumExtra: " + sumExtra);}}
please code in python Forbidden concepts: arrays/lists (data structures), recursion, custom classes You have been asked to take a small icon that appears on the screen of a smart telephone and scale it up so it looks bigger on a regular computer screen.The icon will be encoded as characters (x and *) in a 3 x 3 grid as follows: (refer image1 ) Write a program that accepts a positive integer scaling factor and outputs the scaled icon. A scaling factor of k means that each character is replaced by a k X k grid consisting only of that character. Input Specification:The input will be an integer such that 0 < k ≤ 10. Output Specification:The output will be 3k lines, which represent each individual line scaled by a factor of k and repeated k times. A line is scaled by a factor of k by replacing each character in the line with k copies of the character. [refer image2]

Create an array and store 10 multiples of 5 and print it out. Use for loop to generate the multiples and then print them out using a second for loop. 5 10 15 20 25 30 35 40 45 50 Note: You cannot get any credit if you don't use array or for loop. JAVA CODE class Main {public static void main(String[] args) {}}
Exercise 1: //The max function the max between a and b, it returns a if a == //b public double max(double a, double b); //The mult function returns the result of a * b public double mult(double a, double b); //The exist in array function returns the index of the element //‘a’ if //‘a’ exist in array ‘arr’ otherwise returns ‘-1’ public int existsInArray(int [] arr, int a); //Are array equals method compares two arrays and returns true // if the elements of array ‘a’ are equal to elements of array // ‘b’, element by element. If equals it returns 0, it returns - // 1 if not public int areArrayEquals(int [] a, int [] b); Devise four executable test cases for every method in the JUnit notation. See the attached handout for a refresher on the notation.
