    With this definition in mind, do any of those have both magnitude and direction?

    Well #1 im not sure about, but #2 adn #3 i kno dont deal with direction right? I'm pretty sure they all have magnitude because they all deal with numbers.

    Yes 2 and 3 are just magnitudes.

    But if you are confused with 1, just ask yourself this, do you normally say "the number of people attending a football game at 37 degrees to the x-axis"?
