We are given coordinates of A, B, C and D :
A(2, 4), B(9, 8), C(-1, 2), and D(3, -5).
Now, we need to find the slopes of AB and CD.
Slope of AB is :
.
Slope of CD is:
.
<em>Slope of CD is negative reciprocal of slope of slope of AB. </em>
<h3>Therefore, lines AB are CD are perpendicular.</h3>
First subtract the 2 dollars then you will have 6.39 then divid by the .99 wich gives you 6.45 which you round up to 7 copious because you can’t have a 1/2 of a copy
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
