12

Step-by-step explanation:

The median is the middle value when all values are listed in increasing order.

Here, there are 25 values.

The middle value is the 13th value.

There are 2 size 8.

Then there are 9 size 10.

2 + 9 = 11

That accounts for the first 11 values in increasing order.

Then there are 8 size 12.

Since we need the 13th value, and we already have 11 values, we need the second size 12.

The 13th value is size 12, so the median is size 12.

12

if x = 1, then the answer is 3.5
