the last one might be right.
The mean is the average, which is adding all the numbers up and dividing by how many numbers there are. There are 2x(1), 3x(2), 9(3), 9(4), and 5(5).
2+6+27+36+25 = 96.
There were 28 total.
Divide 96 by 28. 3.4 is the average.
The median is the middle number from least to greatest.
3.5 is the median.
What is your question? I don't see one, I am willing to help just need a question and i will try to help!
First, we need to isolate the variable x.
To isolate x, we simply need to multiply both sides by 9, which would result in x = 9
