Mean is just the average of all of them
So... 5 + 4 + 18 + 19 + 12 + 20 + 12 + 12 = 102
Then you divide that number by the amount of numbers you have so 102 / 8 = 12.75 or rounding it up to 13
For median you have to first put them in order from smallest to largest.
So 4 5 12 12 12 18 19 20
Then you have to find the middle number between them but in this case we have two... 12 and 12. Since they're the same number, the median is 12.

Answer:
x = 3
Step-by-step explanation:
4x + 3 = 5x
4x = 5x - 3
4x - 5x = -3
(4 - 5)x = 1x
-1x = -3
x = -1 × (-3)
<u>x</u><u> </u><u>=</u><u> </u><u>3</u>
