7. What prints when the following snippet of code is executed? int x = 4; int y = 3; String result = ""; if (x > 0) { result = "11111"; if (y > 4) { result = "22222"; else { result = "33333"; System.out.println(result);

Given the following Schedule of Three processes P1,P2 and P3 : 

P1----> P2 -----> P3

Knowing that the processes arrived the same time (0ms) and the execution time for them is X,Y,Z respectively .

What is the response time for each of the three processes: 

a. P1=0, P2 = X , P3 = X+Y

b. P1 = X , P2 = Y , P3 = X+Y+Z

c. P1 = 0 , P2 = X+Y , P3 = X+Y+Z

d. None of the above

7. Given y-ax2+bx+c (a>0; b>0). Determine if the function is: (a) Strictly increasing or strictly decreasing (5 points) (b) convex, concave or linear (5 points)
