Question

Which of the following is a quantity that could be represented by the number 2 * 10^(-3)

Answer 1

next time please post the choices

A. the diameter (in meters) of an atom

B. the time it takes (in minutes) to blink

C. the occupancy limit of a pizza restaurant

D. the annual salary of a high school math teacher

Answer 2

that being said, 2 * 10^(-3) is 0.002

you can obviously eliminate C&D because both C+D must be numbers above 1

so you're down to A or B, any ideas which one is better? try doing a bit of research if you are still unsure
