(a)
different possibilities
(b)
So, there is a 1 in 4 chance that both dice will show an even.

Answer: Rectangle
If you let
P = (0,0)
Q = (0,b)
R = (a,b)
S = (a,0)
you'll be able to find that
PQ is a vertical line with undefined slope
QR is a horizontal line with slope 0
so PQ and QR form a right angle as they are perpendicular lines
You'll find this with the other line pairings as well. We'll have four right angles
Answer:
there is a strong negative correlation between data so the chosen model is a good fit
Step-by-step explanation:
a correlation coefficient close to -1 means that the model is considered a good fit; if correlation is greater than 0.8 then it's described as strong
