The coefficient of correlation is independent of change of scale and origin of the variable X and Y. Change of origin means some value has been added or subtracted in the observation. If we divide all observations with x then new mean =initial mean/x.

<em>combine like terms</em>

Answer:
the answer is x + 9
Step-by-step explanation:
3 times x equals 3x and 3 times 3 equals 9 -2X
you need to add like terms together
3x+2x=5x
and then 9 is by itself
so x+ 9 is the answer
hope this helps :-)
True - since the outlier is way off it will cause your average to mess up which is why we test multiple times to make sure we are more accurate with our numbers
