If the pond were a rectangle, then:
length=15 m
width=6 m
We would have to calculate the perimeter of this rectangle.
Perimeter of a rectangle=2(length)+2(width)
Perimeter of this rectangle=2(15 m)+2(6 m)=30 m+12 m=42 m
We need 42 m and I only have 40 m, therefore, it would not be enough for fencing the pond.
I think it’s 300 the answer
7:15 since there are 7 salty snacks and 15 sweet snacks
Answer:
(n-1)a
Step-by-step explanation:
In this question we have a single factor with number of levels equal to a.
Then the Number of observations that are within each factor setting is equal to n.
So the total number of observations = na.
We have the degrees of freedom for SS(Error) = n - k,
Now, n is the total number of observations,
While,
k is the number of levels of the single factor.
Therefore the degrees of freedom is = na - a
= (n - 1)a.
