A certain device requires a passcode to be used. The passcode must meet both of the following requirements. • The passcode must be 4 digits long. • The passcode must not start with a zero (0) digit. Assume that pass is a properly declared and initialized int variable. Which of the following expressions will evaluate to true if pass is an acceptable passcode?

A store sells rope only in whole-foot increments. Given three lengths of rope, in feet, the following code segment is intended to display the minimum length of rope, in feet, that must be purchased so that the rope is long enough to be cut into the three lengths. For example, for lengths of 2.8 feet, 3 feet, and 5 feet, the minimum length of rope that must be purchased is 11 feet. For these values, the code segment should display 11. As another example, for lengths of 1.1 feet, 3.2 feet, and 2 feet, the minimum length of rope that must be purchased is 7 feet. For these values, the code segment should display 7. In the following code segment, len1, len2, and len3 are properly declared and initialized double variables representing the three lengths of rope. double total = len1 + len2 + len3; int minLength = (int) (total + 0.5); System.out.print(minLength); Which of the following best describes the behavior of the code segment?
