r 2 representa la proporción de variación en la variable y que es explicada por la variable x. II. Un coeficiente de correlación de −0,9 indica una asociación negativa débil entre x e y. tercero Un coeficiente de correlación de 0,5 significa que el 50 % de la variación en los valores de y se explica por los valores de x. IV. Cuando r = 1, existe una relación perfecta de causa y efecto entre la variable x y la variable y.

0/5 is 0, 2/0 is undefined, and 0/0 is indeterminate.

answer:   c ?

step-by-step explanation:

answer: an 8-foot rope is tied from the top of a pole to a

stake in the ground, as shown in the diagram

below

step-by-step explanation:

a.) list the factors of 40.

1/2/4/5/8/10/20/40

b.) list the factors of 40 that represent the number of cans that could be on each shelf.

5

c.) how many different arrangements of cans are possible?

just one because if you put more on one shelf you will go way over 40 and the cabinet will probably break.

d.) what are the possible arrangements of the cans?

put 5 cans on each self to reach 40 cans in total.

e.) which arrangement uses all the shelves?

5 because you can put 5 cans on each shelf, and since there are 8 shelfs you are equally going to get 40 cans.
