Mathematics

Answer:

\boxed {\boxed {\sf range= 6}}

Step-by-step explanation:

The range of a data set is the difference between the biggest value and the smallest value.

We are given this data set:

  • 8, 4, 6, 6, 8, 2, 6, 5

If we order it from smallest to largest:

  • 2, 4, 5, 6, 6, 6, 8, 8

We see that the smallest value is 2 and the largest is 8. Now we can find the range.

  • range= largest value - smallest value
  • range= 8-2
  • range= 6

The range for the data set is <u>6.</u>

Range = highest number - lowest number
Highest number = 8
Lowest number = 2
Range = 8-2 = 6

6 is the range

Nina knows that the average of the x-intercepts represents the line of symmetry for a quadratic function through the x-axis. Whi
Ghella [55]

Answer:

To get the x-intercepts of the function, f(x) = 4x2 – 24x + 20

It has to be equated to zero and the values of x are the x-intercepts. So,

4x2 – 24x + 20 = 0

The resulting equation is a quadratic equation which can be solved by different methods. The solution is

x = 5, 1

The average therefore is:

(1+5/)2 = 3

Which table shows a function whose range has exactly three elements
Rudik [331]
<h2>Answer:</h2>

The table which shows that a function's range has exactly three elements is:

         x      y

         3      8

        4      6

        5      12

        6       8

<h2>Step-by-step explanation:</h2>

<u>Domain of a function--</u>

The domain of a function is the set of all the x-values i.e. the value of the independent variable for which a function is defined.

<u>Range of a function--</u>

It is the set of all the y-value or the values which are obtained by the independent variable i.e. the values obtained by the function in it's defined domain.

a)

     x      y

     1      4

     2      4

     3       4

Domain: {1,2,3}

Range: {4}

Hence, the range has a single element.

b)

     x      y

     3      8

     4      6

     5      12

     6       8

Domain: {3,4,5,6}

Range: {6,8,12}

Hence, the range has three element.

c)

     x      y

     0     5

     2      9

     0      15

This relation is not a function.

because 0 has two images.

0 is mapped to 5 and 0 is mapped to 15.

d)

     x      y

     1      4

     3     2

    5      1  

    3      4

This relation is not a function.

because 3 has two images.

3 is mapped to 2 in the ordered pair (3,2) and 3 is mapped to 4 in the ordered pair (3,4)

When Judy worked 4 hours and Ben worked 1 hour, their combined pay was $75. When Judy worked 2 hours and Ben worked 6 hours, the
arsen [322]

Answer:

$15

Step-by-step explanation:

let the hourly rate of pay for Ben  = B

let the hourly rate of pay for Judy  = J

Judy worked 4 hours and Ben worked 1 hour, their combined pay was $75;

              4J + B = 75 ----- i

Judy worked 2 hours and Ben worked 6 hours, their combined pay was $120

               2J + 6B  = 120 --- ii

Now, we should solve the expression;

   Multiply equation ii by 2 and equation i by 1;

 

            4J + B = 75 ----- i    x 1  ;    4J + B  = 75          -- iii

            2J + 6B  = 120 --- ii  x 2 ;   4J + 12B  = 240    ---iv

Now,

 equation iv - iii;

                   11B  = 165

                      B  = $15

So, solving for J;

          4J + B = 75

         4J + 15  = 75

          4J  = 75 - 15  = 60

          J  = $15
