Select the statements that describe a vector. Check all that apply.Vectors have a size only.Vectors have a size and a direction.Vectors are indicated with arrows.Vectors can have only positive values.Vectors can have positive or negative values.

A vector has both magnitude (size) and direction, so “Vectors have a size and a direction” is correct; size alone describes a scalar. Vectors are commonly represented by arrows, with the arrow’s length showing magnitude and its orientation showing direction. Vector components can be positive or negative depending on their direction relative to the chosen coordinate axes, so they are not limited to positive values.
