Use technology to determine an appropriate model of the data. (-1,0), (1,-4), (2,-3), (4,5), (5,12)
Vinil7 [7]
By graphing the points, The best mode of the data will be the quadratic function

There is 5 steps to find the quadratic function that models the data.

First step           ⇒ Plot the data pairs (x, y) in a coordinate plane.
                              which are the blue circles in the attached figure

Second step     ⇒ Draw the parabola you think best fits the data.
                             Which is the red function in the attached figure.

Third step         ⇒ Estimate the coordinates of three points on the
                             parabola, which are (-1, 0), (2, -3), and (5, 12).

Fourth step       ⇒ Substitute the coordinates of the points into the model
                            y = ax² + bx + c
                            to obtain a system of three linear equations.

                            a - b + c = 0           ---------(1)
                            4a + 2 b + c = -3    ---------(2)
                            25a + 5 b + c = 12 ---------(3)   

Fifth step   ⇒ Solve the linear system.
                      By using the calculator
                      a = 1 , b = -2 , c = -3

So, the quadratic model for the data is ⇒ y = x² - 2x - 3

A play has tickets available for 8 orchestra seats and 12 balcony seats. The next person to buy a ticket will be randomly assign
qaws [65]

The probability that the next person will be assigned an orchestra seats is 2/5.

<h3>What is Probability?</h3>

Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.

Here, Available Orchestra seats = 8

            Balcony seats = 12

      Total available seats = 12 + 8 = 20

  Probability = Favorable Outcome / Total Outcome

  Probability of getting orchestra ticket = 8/20

                                                                 = 2/5

Thus, the probability that the next person will be assigned an orchestra seats is 2/5.

The sum of two numbers is 22. the difference is 6 what are the two numbers?
Nataly [62]

Answer:

8,14

Step-by-step explanation:

Let one number = x

Other number = 22-x

x - (22-x) = 6

x - 22 +x =6

2x = 6 + 22

2x = 28

x = 28/2

x = 14

Other number = 22 - 14 =8
