Which points are coplanar and non collinear ?

Two points are collinear if there exists a line in which they both lie.

Two points are coplanar if there exists a plane in which they both lie.

If you pick any two points, you can always draw a line (and infinitely many planes) passing through them.

So, you need at least three points in order to have points that are coplanar and not collinear. For example, the vertices of any polygon form a set of points that are all coplanar (they all lie on the plane of the polygon), but are not all collinear.

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

for a it would be 24 children.

for b i don't understand the question. is it saying for each individual person they pick 5 reds to 7 greens or is it the whole group. clarify and i hope this can you.
