An article describes a study in which a new type of ointment was applied to forearms of volunteers to study the rates of absorpt

irinina [24]

Answer:

There were 28 different choices for the six locations to apply the new ointment

Step-by-step explanation:

The order in which the location are chosen is not important, which means that we use the combinations formula to solve this question.

Combinations formula:

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

Two events, A and B are independent, if:

$P(A \cap B) = P(A)P(B)$

How many different choices were there for the six locations to apply the new ointment?

Six locations from a set of 8. So

$C_{8,6} = \frac{8!}{6!2!} = 28$

There were 28 different choices for the six locations to apply the new ointment

If one x-value maps to many y-values, does the relation represent a function?

Dahasolnce [82]

Answer:

Step-by-step explanation:

This is the general rule for any function, where a function cannot have more than one x value for every y value, there is only one output for every input.

You can also use the vertical line test which states that anything that hits the line more than once is not a function.
