7 0

Answer:

  0

Step-by-step explanation:

The sorted data set is ...

  1 2 3 3 5 7 8 9

The median is the average of the middle two numbers: (3+5)/2 = 4.

Replacing one of the 3s with a 1 makes the data set be ...

  1 1 2 3 5 7 8 9

The average of the middle two numbers is (3+5)/2 = 4.

The median increases by 4 - 4 = 0.

Answer:

  g(x) = |x -7|

Step-by-step explanation:

The form given for your answer has parameters 'a', 'h', and 'k'. The parameter 'a' is the vertical scale factor. Since g(x) is a translation only, that factor is 1. The parameters (h, k) identify the translation (right, up). The translation is 7 units right and 0 units up, so (h, k) = (7, 0).

Filling in these values of the parameters, your g(x) is ...

  g(x) = |x -7|

Swimsuit discounted 65% on sale for $20.30.
Dafna1 [17]
Original price of the swimsuit = x 

If something was discounted 65%, that means you are paying 35% for it. 
(100% - 65% = 35% or 0.35) 

x(0.35) = 20.30

divide both sides by 0.35

x = 58 

The swimsuit was originally 58 dollars.

30 POINTS Please Help (: Thank you.<br> I have to solve for x and z.
MrRa [10]

Answer:

13 =x

z =88

Step-by-step explanation:

7x+1 is a vertical angle to 9x -25

That means they are equal

7x+1 = 9x-25

Subtract 7x from each side

7x-7x+1 = 9x-7x-25

1 = 2x-25

Add 25 to each side

1+25 =2x-25+25

26 = 2x

Divide by 2

26/2 = 2x/2

13 =x

7x+1 and z are supplementary angles, which means they add to 180

7x+1 +z = 180

We know x

7(13) +1 +z = 180

91 +1 +z = 180

92 +z = 180

Subtract 92 from each side

92-92 +z = 180-92

z =88
