Answer:

A or D

Step-by-step explanation:

I would think that it would be a valid sample because the first nine people were selected to participate.  But, it also could not be a valid sample because it is only a short study.  If there are more than one answer, I would say those two, but if it is only one answer, it is either A or D.  I think....

I can’t figure out what the half circle means the answer options are 163,129,149 and 186
vodka [1.7K]

Answer: 129

Step-by-step explanation: First find the area of the circle. Since we know the area of a circle is πr²  (pi multiplied by the radius squared) we can find the area of the half circle. The radius is 5 (because radius is half of the diameter)

Area=3.14(5)²

       =3.14(25)

       =78.5

But since this is just a half circle, divide this by 2

That will get 39.25

Then add this to the area of the rectangle (L*W) which is 90

That will get about 129
