9,10,12,x,20,25; the median is 14.

Step-by-step explanation:

In statistics, the median is a central measure, which represents the value placed in the middle.

In this case, the middle value is between 12 and x. To find the median, we have to find the mean between those two values

But, we know by given that the median is 14, we replace it and solve for

Therefore, the unknown value is 14.

how many players are there?

step-by-step explanation:

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
