Answer:

D

Step-by-step explanation:

Given

| 2 - 4n | - 4 = 34 ( add 4 to both sides )

| 2 - 4n | = 38

The absolute value function always returns a positive value but the expression inside can be positive or negative, that is

2 - 4n = 38 OR -(2 - 4n) = 38

subtract 2 from both sides

- 4n = 36 ( divide both sides by - 4 )

n = - 9

OR

-(2 - 4n) = 38

- 2 + 4n = 38 ( add 2 to both sides )

4n = 40 ( divide both sides by 4 )

n = 10

As a check

Substitute these values into the equation and if both sides are equal then they are the solutions.

n = - 9

| 2 + 36 | - 4 = | 38 | - 4 = 38 - 4 = 34 = right side

n = 10

| 2 - 40 | - 4 = | - 38 | - 4 = 38 - 4 = 34 = right side

Thus the solutions are { - 9, 10 } → D

Answer:

Your answer would be 3/7 or $\frac{3}{7}$

____________________________________________________

Step-by-step explanation:

In this type of question, we would need to find out the chances of getting something as an outcome, and that would be expressed as a fraction.

In order to find out the chance (or likeliness) of an outcome, we would need o use the information provided in the question.

Let's give you some key information that was given to us.

Key information:

4 animal characters

3 Human characters

With the information above, we can figure out what would be the probability of an outcome.

The question is saying "what is the probability of the computer picking a human character." That means that the amount of human characters would go on our numerator.

There's not only human characters, but there are 4 animal characters too, so that would be used to give us our total. the "4" will be added to our denominator.

Now, let's write it in a fraction.

Fraction: $\frac{numerator}{denominator}$

We know that we are trying to find the probability of getting a human character, so "3" would go on our numerator.

For our denominator, we would add up both numb ers since it would have to be the total amount of options in order to find the probability, and that would be "7" since 4 + 3 = 7.

When you put those into a fraction. Your FINAL answer would be:

3/7 or $\frac{3}{7}$
