Answer:
Yes, there is one outlier (lower)
Step-by-step explanation:
Looking at the distribution of the lower/smallest observation, we can see that there is a values in the lower/smallest that is very far from others. See the attached box-plot for understanding.
The median is the line in the middle of the box-plot.
The Lower fourth is the lower whisker line and upper fourth is the upper whisker line. The lower box (just below the median) line is the 1st quartile and the upper box line (just above the median) is 3rd quartile.
Answer:
Step-by-step explanation:
If the area is
and area = length * width and our width is given as x + 4, then the length is found by dividing the area by the width. You could do that using long division, but it's easier using synthetic division.
-4 | 1 -2 -40 -64
______________
1
This is how you start. The -4 inside the box comes from the factor you are dividing by. If x + 4 = 0, then x = -4. The numbers after are the coefficients from each descending power of x. Multiply the -4 by the 1 and put that product up under the -2 and add to get:
-4 | 1 -2 -40 -64
-4
--------------------------------
1 -6
Now multiply -4 by -6 and put that product up under the -40 and add:
-4 | 1 -2 -40 -64
-4 24
-------------------------
1 -6 -16
Multiplying -4 by -16 gives you 64 so when you add you get a remainder of 0.
The numbers under the line give you the depressed polynomial
That gives you the expression for the length. That's C.
