N-8=21 should be the answer
Hello!
As we can see, our a value, which would be the coefficient of
, which determines our slope, is negative, meaning that this whole line is negative.
Furthermore, the correlation can be determined using the r value of the linear regression, which is around -0.9.
If the r value of the linear regression is close to 1 or -1, let's say around |r| > 0.8, then we can consider the regression a strong correlation, meaning that this is a strong negative correlation, which is answer choice A.
For the answer to the question above, A person drives north 6 blocks, then drives west 6 blocks. the displacement is a straight line from the starting point to the finish in <span>8.49 blocks</span> in a Northwest <span>direction.
The Solution:
</span>A^2+B^2=C^2
6*6+6*6 = sqrt(72)
Answer: x+8
The term 'sum' means 'result of adding two (or more) numbers or expressions'.
