Students were surveyed about their favorite colors. of the students preferred red, of the students preferred blue, and of the remaining students preferred green. If 15 students preferred green, how many students were
surveyed?

Sketch the vector field vector f( vector r ) = 8vector r in the xy-plane. select all that apply. the length of each vector is 8. the lengths of the vectors decrease as you move away from the origin. all the vectors point away from the origin. all the vectors point in the same direction. all the vectors point towards the origin. the lengths of the vectors increase as you move away from the origin.
