Perimeter is when you add the outside of a shape.
For example: if you are finding the perimeter of a rectangle the formula is P= l+w+l+w. I hope this helps !
Answer:
30.4
Step-by-step explanation:
if you want the basic perimeter just add up all the sides
I believe you would create and equation to find x and y.
Answer:
a) True
Step-by-step explanation:
The given statement is true.
where
are data points,
is the mean and n is the number of observations.

The standard deviation express the variation of data from the mean and therefore, have the same unit as the data like lbs, inches, dollars, etc.
Coefficient of variation on the other hand is the ratio of standard deviation and mean. It is also a measure of dispersion but since it is a ratio, the units cancel each other.

Thus, coefficient of variation is dimensionless.
Thus, it is a relative measure.
5% = 5/100 = 1/20;
12% = 12/100 = 3/25;
15% = 15/100 = 3/20;
