The best choice that it would be would be 3
Answer:
Refraction
Step-by-step explanation:
Since the line bends (and this can apply to light too), the line refracts, or changes the angle of direction.
Answer:
The correct option is C
Step-by-step explanation:
From the question we are told that
The number of independent variables is ![n = 3](https://tex.z-dn.net/?f=n%20%3D%20%203)
The number of observation is ![z = 47](https://tex.z-dn.net/?f=z%20%3D%20%2047)
Since n is are independent variables then their degree of freedom is 3
The denominator(i.e z) degrees of freedom is evaluated as
![Df(z) = z - (n +1)](https://tex.z-dn.net/?f=Df%28z%29%20%3D%20%20z%20-%20%28n%20%2B1%29)
![Df(z) = 47 - (3 +1)](https://tex.z-dn.net/?f=Df%28z%29%20%3D%20%2047%20-%20%283%20%2B1%29)
![Df(z) = 43](https://tex.z-dn.net/?f=Df%28z%29%20%3D%20%2043)
So for the numerator (n) the degree of freedom is Df(n) = 3
So for the denominator(i.e z) the degree of freedom is Df(z) = 43
