Suppose that there were a positive correlation between the variables u and v. if v is 12 when u is 10, which of these is most likely to be the value of v when u is 20?

Answer with Step-by-step explanation:

Positive correlation between u and v means:

We can write u and v as

v=ku  where k is some positive number

when u=10,v=12

⇒ 12=k×10

⇒ k=1.2

⇒ v=1.2u

when u=20

v=1.2×20

⇒ v=24

Hence, when u=20, value of v is:

24

10/60

step-by-step explanation:

if you divide 10 by 60 the answer is 0.166666 while if you divide or solve the other problems it equals 0.6
