Question

Which of the following expressions evaluate to 3.5 ?

I. (double) 2 / 4 + 3
II. (double) (2 / 4) + 3
III. (double) (2 / 4 + 3)
(A) I only
(B) III only
(C) I and II only
(D) II and III only
(E) I, II, and III

Answer 1

After evaluating each expression, it's clear that expressions I, II, and III each evaluate to 3.5. The correct answer to the question is (E) I, II, and III.

Step-by-step explanation:

The question asks which of the following expressions evaluate to 3.5:

1. (double) 2 / 4 + 3
2. (double) (2 / 4) + 3
3. (double) (2 / 4 + 3)

Let's evaluate each expression:

1. Expression I: (double) 2 / 4 + 3 = 0.5(double) + 3 = 0.5 + 3 = 3.5
2. Expression II: (double) (2 / 4) + 3 = (double) (0.5) + 3 = 0.5 + 3 = 3.5
3. Expression III: (double) (2 / 4 + 3) = (double) (0.5 + 3) = (double) 3.5 = 3.5

Each expression: I, II, and III evaluates to 3.5. Therefore, the correct answer is (E) I, II, and III.
