The first question's answer is 80% because 100-20 is 80.
The second question is There is not enough information to tell because it doesn't give an amount. It gives us percent so we can't tell how many people are in the survey.
Answer;
A, B, C are coplanar and also A, B, C are collinear.
Explanation;
-For points to be collinear it means they lie on the same line. For rays to be opposite, they should be in the same line making a 180° or a straight line with each other.
-Coplanar means the points lie in the same plane. For these rays to be opposite and collinear the points should lie in the same plane.
Than you check this line of terms
1. 80=160/2
2. 40=80/2
3. 20=40/2
4. 10=20/2
5. 5=10/2
6. 2 1/2 = 5/2 so what mean that choice c. is right sure
