write matlab code 2) Student scores 70 80 75 50 90 96 60 68 56 99 40 78 Using for loop: a) create a variable called avg_all that calculates the average of all student scores. b) create a variable called avg_pass that calculates the average of the students who pass (>=60) the class only. (Any score less than 60 needs to be neglected) 3) Create the following matrix using for nested loops 1 1 1 x = 2 2 2 3 3 3 4) Create a for loop that allows the user to input a number and it gives back the number's factorial. 5) Create the following vector using for loop x=[22 24 26 28 210]
