Answer:

$\{-4, -1, 0, 2, 7\}$

Step-by-step explanation:

The domain of the function is the set of all possible inputs for the function. Therefore, the set of all possible inputs is $\{-4, -1, 0, 2, 7\}$ .

Agata [3.3K]

Answer:

$\begin{array}{cccccc}X&0&1&2&3&4\\Pr&\dfrac{1}{16}&\dfrac{1}{4}&\dfrac{3}{8}&\dfrac{1}{4}&\dfrac{1}{16}\end{array}$

Step-by-step explanation:

A family has four children. If the genders of these children are listed in the order they are born, there are sixteen possible outcomes: BBBB, BBBG, BBGB, BGBB, GBBB, BGBG, GBGB, BGGB, GBBG, BBGG, GGBB, BGGG, GBGG, GGBG, GGGB, and GGGG.

Let X represent the number of children that are girls. Then

1. When X=0, there is one possible outcome BBBB. So

$Pr(X=0)=\dfrac{1}{16}$

2. When X=1, then there are 4 possible outcomes GBBB, BGBB, BBGB, BBBG, so

$Pr(X=1)=\dfrac{4}{16}=\dfrac{1}{4}$

3. When X=2, then there are 6 possible outcomes BGBG, GBGB, BGGB, GBBG, BBGG, GGBB, so

$Pr(X=2)=\dfrac{6}{16}=\dfrac{3}{8}$

4. When X=3, then there are 4 possible outcomes GGGB, GGBG, GBGG, BGGG, so

$Pr(X=3)=\dfrac{4}{16}=\dfrac{1}{4}$

5. When X=4, then there is one possible outcome GGGG, so

$Pr(X=4)=\dfrac{1}{16}$

Now, the probability distribution table is

$\begin{array}{cccccc}X&0&1&2&3&4\\Pr&\dfrac{1}{16}&\dfrac{1}{4}&\dfrac{3}{8}&\dfrac{1}{4}&\dfrac{1}{16}\end{array}$

It costs $2.50 to rent bowling shoes. Each game costs $2.25. You have $9.25. Write and solve an equation to find how many games

Nesterboy [21]

Hi there!

So, 2.25x would represet the total amount of money spent for all the games.

2.25x + 2.50 = 9.25 would be the equation to represent this scenario.

Now to solve: Our goal is the get x alone. Subtract 2.50 (the price of the shoes) from both sides. 9.25 - 2.50 = 6.75.

We are now left with 2.25x = 6.75.

Finally, we divide both sides of the equation by 2.25, which leaves us with x = 3.

So you can bowl for a total of 3 games.

I hope I helped!

Find the value of x .

Bad White [126]

Answer:

Step-by-step explanation:

Because the four angles share a common point and because they start with the top of 2x and end there, the total number of degrees travelled is 360 -- the same as though the origin were at the meeting place of the 4 given angles and the center of a circle.

3x + 3x + 4x + 2x = 360 degrees. Combine

12x = 360 Divide by 12

12x/12 = 360/12

x = 30
