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:
<h2>-4</h2>Step-by-step explanation:
Given the function f(x)=(x+4)², <u>the x intercept occurs at f(x) = 0,</u> substituting f(x) = 0 into the given equation to get the value of x we have;
Taking the square root of both sides
Subtracting 4 from both sides of the equation
Therefore the x intercept of the equation is -4
