Okay so median is the number in the middle and mean is when you add them all up and divide by how many numbers there are
<span>20,28,35,40,132
So 35 is the median
and the mean is </span>20 + 28 + 35 + 132 + 40 = 255 / 5 = 51
the mean is a better way to represent the data because it does not just pick a number from the set of numbers it calculates the average
There are 1.505535375e+24 atoms in 2.50 moles of iron.

A line is perpendiculat to another which has a slope of m if the perpendicular line has a slope of -1/m.
That means that if the product of slopes of two lines is -1, the two lines are perpendicular.
Here, y1=-7/4x, or m=-7/4
The perpendicular should have a slope of -1/m=-1/(-7/4)=4/7
Point A' is at (-2,-2)
Point D' is at (-2,4)
Just multiply each coordinate by 2
