Answer

To solve for y, we calculate as follows:

  1. Calculate ceil(25.0/6):

    ceil(25.0/6)=ceil(4.1667)=5ceil(25.0/6) = ceil(4.1667) = 5

  2. Calculate 30 mod 6:

    30mod6=030 mod 6 = 0

  3. Calculate round(15.0/4):

    round(15.0/4)=round(3.75)=4round(15.0/4) = round(3.75) = 4

  4. Substitute these values into the expression:

    y:=5+0−4=1y := 5 + 0 - 4 = 1

Therefore, the value of y is 1.
