Answer: mean= 16.9

Median= 14

Step-by-step explanation:

Mean= sum of data set/ number of data set

= 118/7 =16.9

Median- the middle number of a data set, to reflect the best measure of the centre, the data set should be arranged in an ascending order

12, 13, 13, 14, 21, 22,23...... 14 is the median

Answer:

x = 55

Step-by-step explanation:

Draw a line parallel to the top and bottom parallel lines so this new line goes through the pointed end of x.

Draw another line parallel to the top and bottom lines through the pointy end of 45.

The bottom angle of the line through 45 is 15 degrees (alternate interior angles.

The top angle is 45 - 15 = 30

The bottom angle of the line going to x is 150 degrees. It and the 30 degree angle make 180. 30 + 150 = 180

One final observation The top angle of made by the line going through x is 180 - 25 = 155

What you have now is

155 + 150 + x = 360

305 + x = 360

x = 360 - 305

x = 55

An you help me now with these |x + 2| + 16 = 1 i need help :( |2x + 6| − 4 = 20 nd help solving
krok68 [10]
|x + 2| + 16 = 1
<u>           - 16  - 16</u>
        |x + 2| = -15
         x + 2 = -15    U    x + 2 = 15
         <u>    - 2     - 2</u>          <u>    - 2    - 2</u>
               x = -17                 x = 13

|2x + 6| - 4 = 20
<u>            + 4   + 4</u>
     |2x + 6| = 24
      2x + 6 = 24    U    2x + 6 = -24
      <u>     - 6    - 6</u>           <u>     - 6      - 6</u>
            <u>2x</u> = <u>18</u>                 <u>2x</u> = <u>-30</u>
             2      2                   2       2
              x = 9                     x = -15
