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 =![n-k-1](https://tex.z-dn.net/?f=n-k-1)
= ![200-3-1](https://tex.z-dn.net/?f=200-3-1)
= ![196](https://tex.z-dn.net/?f=196)
So, Option A is true .
Hence degrees of freedom for testing the statistical significance of individual slope coefficients is 196
D because it is the most specific

Answer: Choice D. 8m, 9m, 10m</h3>
==================================
Explanation:
If a = 8 and b = 9 are the two legs of a triangle and c = 10 is the hypotenuse, then
a^2 + b^2 = c^2
8^2 + 9^2 = 10^2
64 + 81 = 100
145 = 100
We get a false equation as 145 and 100 are two different values. So the original equation is false when (a,b,c) = (8,9,10)
By the converse of the pythagorean theorem, we have proven that this particular triangle is not a right triangle
-------------
Contrast this with something like choice A where we have a = 3, b = 4, c = 5 leading to
a^2 + b^2 = c^2
3^2 + 4^2 = 5^2
9 + 16 = 25
25 = 25
we get a true equation so a triangle with sides 3,4,5 is a right triangle. Choices B and C follow a similar path.
Answer:
Y=2x+(-1)
Step-by-step explanation:
The slope/m = 2/1 and the Y int.= -1 So for it to be in slope intercept form it would look like this Y=2x+(-1).
