Answer:
The fraction.
Step-by-step explanation:
3 
is a mixed number, so the 1 over 2 is the fraction of the whole number.
Answer:
symmetric property
Step-by-step explanation:
The symmetric property states that for any real numbers, a and b,
if a = b then b = a
Answer: D. .400
Step-by-step explanation:
Given : In a multiple regression model involving 44 observations, the following estimated regression equation was obtained.
For this model,
Regression sum of squares =SSR = 600
and Sum of squares due to error =SSE = 400.
Total sum of squares = SST= SSR+SSE
SST= 600+400=1000
The multiple coefficient of determination is given by :-
Substitute values , we get
Thus, the multiple coefficient of determination for the above model is 
Hence, the correct answer is D. .400.
Answer: y+9=-2(x-9)
Step-by-step explanation:
The point-slope equation is 
. All we have to do is fill in all the values except for y and x.
To find m, you use 
. Since we are given 2 points, we cna plug them in.
. Now that we have our slope m, we can fill in the point slope equation.
