Answer:
c. 4 and 42
Step-by-step explanation:
Given
-- independent variables
---- observations
Required
The numerator and denominator degrees of freedom
The denominator degrees of freedom is:
For the numerator, we have:
Hello,
For a given perimeter (P) there are an infinity of Area (A)
Let's say x the length, and y the wide of the rectangle
P=2(x+y)
A=xy
k=x-y >=0
As (x+y)²-4xy=(x-y)²: A²-4P=k² or P=(A²-k²)/4
In primus, you will find a graph (abacus) giving P for a A and k given.
Negative Area or P are excluded.(just remind the first quadrant, A>=0 and P>=0)
