Solution: We are given that the correlation coefficient between the age of a homeowner, x , and the number of years remaining on the homeowner's mortgage, y, is 0.485
We know that coefficient of determination is the percent of the variation in the dependent variable that is explained by the independent variable. The coefficient of determination is the square of correlation coefficient and is denoted by 
Therefore, we have:
denotes
Hence the option 23.5% is correct
Answer:
60
Step-by-step explanation:
80/100 times 75 and you will get 60
In my opinion 360 would be your closest answer.
Looks like the system is
x + 4y - z = -14
5x + 6y + 3z = 4
-2x + 7y + 2z = -17
or in matrix form,
Cramer's rule says that
where 
is the solution for i-th variable, and 
is a modified version of 
with its i-th column replaced by 
.
We have 4 determinants to compute. I'll show the work for det(A) using a cofactor expansion along the first row.
The modified matrices and their determinants are
Then by Cramer's rule, the solution to the system is
