Answer:
13.1mi
Step-by-step explanation:
Length(l) = 4.1mi
Breadth(b) = 2.5 mi
Perimeter of a rectangle = addition of all sides that is = l + l + b + b as a rectangle has 2 opposite equal length and also breadth.
Therefore perimeter = 4.1 + 4.1 + 2.5 + 2.5
= 8.1 + 5
=13.1 mi

Answer:
22 33/40
Step-by-step explanation:
To solve for the coefficient of variation you will need this formula:
CV = (SD/X) x 100
Where: CV = Coefficient of Variance
X = Mean/average
SD = Standard Deviation
To determine which one is more variable, just get the coefficient of both and compare.
AGE SALARY
CV = (6/55) x 100 CV = (4,100/37,000) x 100
= 10.90 = 11.08
Based on the results, salary is more variable because 10.90<11.08.
X= 9....
This is the correct answer.
