Answer:
option B

Step-by-step explanation:
we know that
The<u> correlation coefficient</u> r measures the direction and strength of a linear relationship.The value of r is always between
and 
Using a Excel tool (Correl function)
see the attached table
The value of r is 
well, a and d are true, and b is somewhat false...
angles that are both less than 90 degrees and higher than 0 have to add up to equal 90, not just be less than 90
c, is the same thing. Straight angles are 180 degrees, but supplementary means two angles add up to equal 180 degrees, not just one
so b and c may be true, im not sure
i know that a and d are true, therefore they are not the right answer
