Red Hair
Green eyes: 18
Eye color other than green: 29

Hair Color Other Than Red
Green eyes: 114
Eye color other than green: 650

Consider the relative frequency table.

To the nearest whole percent, what is the value of x in the table?

A) x = 14%

B) x = 15%

C) x = 16%

D) x = 18%

Answer 1

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

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

Answer 2

The answer is x=14% I just took the quiz so.
