Answer:

hope this helps !

Step-by-step explanation:

1) ( 8 x- 16 ) / (x²- 13 x + 22 ) = ( 8 x- 16 ) ( x - 11) ( x -2 ) = 8 ( x-2) ( x-11) ( x- 2 ) = 8/(x-11)

Restriction x ≠ 11 & x ≠ 2

since both values render the denominator = to 0 & we can't divide by 0.

<h3>What is statistics?</h3>

Statistics refers to the method of collecting data for the purpose of analysis, making of inferences and drawing of conclusions about the data collected.

Statistics usually involve numerical data in large quantities.

Statistical data can be used to make predictions about future events. They are also used to make decisions. For example, the statistical data of soccer players such as games/goal ratio, number of complete dribbles per match, number of successful take-ons, number of tackle or interceptions per game can be used in deciding which soccer player a football team should buy.

In the given scenario, Coach Salinas wants to compare the kicking statistics for kickers on their team in order to find the kicker with the greatest goal success rate.

To do this, Coach Salinas should:

  1. determine the kicker who has the best accuracy
  2. determine the kicker has the highest number of field goals per game.

In conclusion, statistical data is important in making decisions.

Kathryn's school is selling tickets to a choral performance. On the first day of ticket sales the school sold 6 adult tickets an
san4es73 [151]

Answer:

Student tickets cost $8 and adult tickets cost $5.

Step-by-step explanation:

12a + 12y = 156

6a + 11y = 118

We can multiply the second equation by -2 to try and cancel out the a variable.

12a + 12y = 156\\-12a - 22y = -236\\\\-10y = -80\\y = 8

Now that we know that the student tickets cost $8, we can substitute it into an equation to find the value of a, the adult tickets.

12a + 12\cdot8 = 156\\12a+96=156\\12a=60\\a=5

So, adult tickets cost $5 and student tickets cost $8.

Hope this helped!
