Answer:
The correct option is C
Step-by-step explanation:
From the question we are told that
The number of independent variables is 
The number of observation is 
Since n is are independent variables then their degree of freedom is 3
The denominator(i.e z) degrees of freedom is evaluated as
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
Answer:
Wrong
Step-by-step explanation:
The student is wrong. Two angles are coterminal if and only if the difference between their measures is a multiple of 360°.
The difference between the angles 180° and –180° is 360°, and they are coterminal. Therefore the student is WRONG.
Answer:
agree

Answer:
754.2
Step-by-step explanation:
First of all, we cannot solve the question the way it is. We need to make 0.1 into a whole number. If we move the decimal to the right, once, then it will become the number one.
Of course, what we do to one, we have to do to the other. We move the decimal to 75.42 to the right one. Now it is 754.2
That looks like the answer. The reason is because we are now dividing by one. Something divided by one, will always be itself.
Now we have the answer of 754.2.
