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.

We have to find to solution for the equation


The solution of the above equation is the intersection of F(x) and G(x).
From the graph it is noticed that both graph intersects each other at (0,1) and (2,4).
The x-coordinates of these points are the solutions of the given equation.
Therefore the solution of given equation are 0 and 2.
Therefore option A and C are correct.
