Suppose that there were a positive correlation between the variables u and v. If v is 24 when u is 10, which of these is most li
sveta [45]

Answer:

The correct answer is 48, given by option c.

Step-by-step explanation:

This question can be solved by proportions, using a rule of three.

Positive correlation means that the variables are directly proportional, and thus, we apply cross multiplication.

If v is 24 when u is 10, which of these is most likely to be the value of v when u is 20?

24 - 10

x - 20

Applying cross multiplication:

10x = 24*20

Simplifying both sides by 10:

x = 24*2 = 48

The correct answer is 48, given by option c.
