Which of the following could be used to replace /* missing code */ so that the code segment works as intended?

• (int) (rn * max) + min

• (int) (rn * max) + min - 1

• (int) (rn * (max - min)) + min

• (int) (rn * (max - min)) + 1

• (int) (rn * (max - min + 1)) + min

Which of the following statements assigns a random integer between 1 and 10, inclusive, to rn ?

• int rn = (int) (Math.random()) * 10;

• int rn = (int) (Math.random()) * 10 + 1;

• int rn = (int) (Math.random() * 10);

• int rn = (int) (Math.random() * 10) + 1;

• 
  int rn = (int) (Math.random() + 1) * 10;

Which of the following can replace /* missing code */ so that the method works as intended

• Math.sqrt(x ^ 2, y ^ 2, a - b)

• Math.sqrt((x + y) ^ 2) / Math.abs(a, b)

• Math.sqrt((x + y) ^ 2 / Math.abs(a - b))

• Math.sqrt(Math.pow(x + y, 2) / Math.abs(a, b))

• Math.sqrt(Math.pow(x + y, 2) / Math.abs(a - b))

Which of the following best explains the effect of simultaneously changing x <= 4 to x < 4 in line 1 and y < 4 to y <= 4 in line 3 ?

• "a" will be printed fewer times because while each output line will have the same length as before, the number of lines printed will decrease by 1.

• "a" will be printed more times because while the number of output lines will be the same as before, the length of each output line will increase by 1.

• "a" will be printed the same number of times because while the number of output lines will decrease by 1, the length of each line will increase by 1.

• "a" will be printed more times because both the number of output lines and the length of each line will increase by 1.

• The output of the code segment will not change in any way.
