Question

question: 1
the ap exam uses the following relational (comparison) operators: =, ≠, >, <, ≥, and ≤.
as well, and, or and not are used instead of &&, || and !=.
a comparison using a relational operator evaluates to a boolean value. for example, a = b evaluates to true if a and b are equal; otherwise, it evaluates to false.
determine what the following expression would evaluate to.
(9 ≠ 7 and 17 < 4) or 65 < 9
yes
true
false
no

Explanation:

Step1: Evaluate each comparison

• \(9

eq7\) is \(true\) because \(9\) and \(7\) are not equal.

• \(17 < 4\) is \(false\) because \(17\) is greater than \(4\).
• \(65 < 9\) is \(false\) because \(65\) is greater than \(9\).

Step2: Evaluate the AND operation

\((9
eq7\ AND\ 17 < 4)\) is \(false\) since \(true\ AND\ false\) is \(false\) (the AND operation requires both operands to be \(true\) for the result to be \(true\)).

Step3: Evaluate the OR operation

\((false\ OR\ 65 < 9)\) is \(false\) since \(false\ OR\ false\) is \(false\) (the OR operation requires at least one operand to be \(true\) for the result to be \(true\)).

Answer:

false
