The tree is 25 feet log becuase the shadow of the tree is 5 times bigger than the shadow of the pole so the tree should be 5 times bigger than the vertical pole which is 5 feet long.
Answer:
the value of x=9 and AB(h)=9.396
Rational. irrational numbers are numbers that never end.
The answer to your question is C.
Answer:
196
Step-by-step explanation:
Formula of degree of freedom for simple regression = n-2
Formula of degree of freedom for multiple regression = n-k-1
We are given the case of multiple regression and there are three independent variables.
So, k = 3
n = 200
So, Degree of freedom for multiple regression =
=
=
So, Option A is true .
Hence degrees of freedom for testing the statistical significance of individual slope coefficients is 196
