Mean = 8+6+5+7+4/5 = 30/5 = 6
Median = 6
Both the mean and median are 6
For the answer to the question above, the power of "y" doesn't influence descending order for x even if it is higher than power of x.
Unordered polynomial is
7x3y3 + 4 - 11x5y2 - 3x2y
Polynomial in descending order looks like this
-11x5y2 + 7x3y3 - 3x2y + 4
Degree of the second term is 5 ( because of x5 )
Since work = force * distance, the answer would 5*.5, which is 2.5 J
Plug the given x and y values (x, y) into the equations and solve
It look like the second equation is the answer.
