Answer:

Correct choice is A

Step-by-step explanation:

You are given the table

\begin{array}{cccc}&\text{Green eyes}&\text{Other eye color}&\text{Total}\\\text{Red hair}&18&29&47\\\text{Other hair color}&114&650&764\\\text{Total}&132&679&811\end{array}

Find the probabilities:

\begin{array}{cccc}&\text{Green eyes}&\text{Other eye color}&\text{Total}\\\text{Red hair}&\dfrac{18}{811}&\dfrac{29}{811}&\dfrac{47}{811}\\ \\\text{Other hair color}&\dfrac{114}{811}&\dfrac{650}{811}&\dfrac{764}{811}\\ \\\text{Total}&\dfrac{132}{811}&\dfrac{679}{811}&\dfrac{811}{811}\end{array}

Instead of x should be

\dfrac{114}{811}\approx 0.14=14\%.

Andre constructs the image of line n under a dilation centered at point O that is not on line n. Becca construct a different ima
GenaCL600 [577]
<em /><u><em /></u>I think that both lines will show only 1 line because 1 line will be on top of the other. I believe this because both lines are dilated with its center at point O which does not lie on line n. Whatever dilation Andre uses may also be the dilation used by Becca since their lines centered at point O. Both lines will have the same slope and share the same coordinates.
