Answer:

Imma rewrite the question as: 2+6/41

2+6=8

i think since the letters were next to each other u multiply?? Is so...:

4x1=4

8+4=12

=12

but if u add the letters next to eachother....

2+6=8

4+1=5

8+5=13

=13

or if u use “41” as a whole number and add it in..:

2+6=8

8+41=49

=49

Which term best describes the association between variables A and B?

Answer: Choice B) negative linear association

=================================

Reasoning:

The points all go downhill as you move from left to right. We can draw a straight line that is fairly close to all of them. This is known as the regression line. The regression line having a negative slope tells us the linear association is negative. This means the correlation coefficient r is negative, so, $-1 < r < 0$ (r = -1 is not possible as not all points fall on the same straight line)
