The two-way table shows the estimated number of students who will enroll in three area high schools next year. a 5-column table
mr Goodwill [35]

Answer:

A. 0.2

Step-by-step explanation:

First make the table.

                                          <u>10-grade</u>  <u>11-grade</u>  <u>12-grade</u>  <u>Total</u>

<u>Woodson high school </u>    |     110     |     120    |      80     |   310   |

<u>Valley high school </u>          |     180    |     150    |     120     | 450   |

<u>Riverside high school </u>     |     160    |     140    |     200    | 500   |

<u>Total </u>                                 |     450   |     410    |     400    | 1260 |

Question: In decimal form, to the nearest tenth, what is the probability that a randomly selected riverside high school student is in twelfth grade?

First, find 12-grade and riverside high school number. 200. Take the total lined up with total number, which is 1260, and divide 200 divided by 1260.

200/1260=0.2

The answer is 0.2.

Hope this helps!

If not, I am sorry.

Sketch the graph of each rational function showing all the key features. Verify your graph by graphing the function on
Sonja [21]

Answer:

The graph crosses the x axis at x=0. For x> 0, it rises to a maximum value and then decreases toward y= 0 as x goes to infinity. For x< 0, it decreases to a minimum values then rises toward y= 0 as x goes to negative infinity. y= 0 is a horizontal asymptote but the graph crosses y= 0 at x= 0.

Step-by-step explanation:

A common mistake that students make is to think that a graph cannot cross a slant or horizontal asymptote. This is not the case! A graph CAN cross slant and horizontal asymptotes (sometimes more than once). It's those vertical asymptote critters that a graph cannot cross.
