Answer:

B. Divide 124 by 229.

Step-by-step explanation:

Given the table

\begin{array}{cccc}&\text{Action}&\text{Drama}&\text{Total}\\ \\\text{Male}&105&124&229\\ \\\text{Female}&99&151&250\\ \\\text{Total}&204&275&479\end{array}

The <u>joint relative frequency</u> is the ratio of the frequency in a particular category and the total number of data values.

The total number of males =229

The number of males that like drama =124

So, to find the joint relative frequency of being male and attending a drama movie, you should divide 124 by 229.

Step-by-step explanation:

Let x be the number of 2 point baskets made and y be the number of 3 point baskets made

:

1) x + y = 26

:

2) 2x + 3y = 60

:

solve equation 1 for x and substitute in equation 2

:

x = 26 - y

:

2(26 - y) +3y = 60

:

52 -2y +3y = 60

:

y = 8

:

x = 26 - 8 = 18

:
