Javier has 4 boxes of comic books. The mean number of books in each box is 25 . Which number line shows what could happen to the mean if he fills two more boxes, one with 26 comic books and one with 30 comic books?

The probability is 15%.

The answer you are looking for is 15%.

To find this answer, you must add up all the CDs to find the total. The total number of CDs is 40, which you divide into 6 (6/40). In doing so, you'll get 0.15, which you multiply by 100 to make it a percent. Thus making the answer 15%.

The correct answer is a. 3x + 6

In order to find a compound function, you must use the first letter in the function (in this case f) and plug the second letter (g) in where you see x's.

f(x) = x + 2

f(g(x)) = (g(x)) + 2

f(g(x)) = (3x + 4) + 2

f(g(x)) = 3x + 6

Final answer:

To find the composition (g ° f)(x), substitute f(x) into g(x) and simplify. The correct answer is 3x + 10.

Explanation:

To find (g ° f)(x), also known as the composition of the functions g and f, you would substitute f(x) into g(x). This means we are looking for g(f(x)):

First, we have f(x) = x + 2.

Then, g(x) = 3x + 4.

To compose g with f, we replace every instance of x in g(x) with f(x). So, g(f(x)) becomes 3(x + 2) + 4.

We simplify this to get 3x + 6 + 4.

And finally, combining like terms gives us 3x + 10.

Therefore, the correct option is (g ° f)(x) = 3x + 10, which is choice b.

The sum of 6 and 3: 6+3

The difference of 6 minus 3: 6-3

The sum of 6 and 3 divided by the difference of 6 minus 3: [tex]\frac{6+3}{6-3}[/tex][tex]=\frac{9}{3}=3[/tex]

I hope this helps :)

Final answer:

To solve the expression given in the question, perform subtraction first (6-3), then addition (6+3), and finally, divide the sum by the difference to get the answer, which is 3.

Explanation:

The question asks us to find the sum of 6 and 3 divided by the difference of 6 minus 3. To find this, we must apply the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, Addition and Subtraction from left to right).

Firstly, let's find the difference of 6 minus 3:
6 - 3 = 3.

Now we shall find the sum of 6 and 3:
6 + 3 = 9.

Lastly, we divide the sum by the difference we found earlier:
9 / 3 = 3.

So the answer to the question is 3.

Step-by-step explanation:

Given : Israel added $120 to his savings. This added amount represents 1/6 of his total savings.

To Find : If s represents the total savings, which equation could be used to determine the value of s?

Solution :

Israel added $120 to his savings.

This added amount represents 1/6 of his total savings.

Let s be the total savings

So, ATQ

[tex]\frac{1}{6}s = 120[/tex]

So, The equation could be used to determine the value of s is [tex]\frac{1}{6}s = 120[/tex]

The t's cancel out. on the right.  You are left with u on the right.

0.75(x+20)=2+0.5(x-2)

Distribute on both sides

0.75x+15= 2+0.5x-1

Add common factors

0.75x+15=1+0.5x

Subtract 0.5x on both sides

0.25x+15=1

Subtract 15 on both sides

0.25x=-14

Divide by 0.25 on both sides

x = -56

The value of x that will make both equations to be equivalent to each other is = -56

From the equation:

0.75(x + 20) = 2 + 0.5(x - 2)

Open brackets

0.75x + 15 = 2 + 0.5x - 1

Collect like terms

0.75x - 0.5x = 2 - 1 - 15

0.25x = - 14

Divide both sides by 0.25

[tex]\mathsf{\dfrac{0.25x}{0.25} =\dfrac{ - 14}{0.25}}[/tex]

x = -56

Therefore, we can conclude that the value of x that will make both equations to be equivalent to each other is -56

Given function: c(x) = 0.5x+70.

Where c is the cost (in dollars) and x is the number of miles you drive the truck.

If we compare given function by slope-intercept form y=mx+b, we get

Slope m = 0.5 in fractions could be written as 1/2.

And y-intercept b =70.

So, in order to graph it, we need to plot y-intercept at 70 first and then plot some more points using rise/run = 1/2.

The red line is the graph for the given function.

We can see that starting value of cost is $70 for 0 number of miles.

x values represents domain and C(x) represents range.

We can take x values greater than or equal to 0 and C values greater than equal to 70.

Therefore, Domain: x≥0 and Range : C(x) ≥ 70.

Remember that parentheses come first. Follow PEMDAS

Answer:

The  speed of air in still air =570 mph and

speed of wind = 40 mph

Step-by-step explanation:

Given that plane travelled 2135 miles in 3.5 hours with the wind.

Let the velocity of plane be x and that of wind be y.

Then with the wind speed =x+y and

against the wind the speed = x-y

Use distance = time x speed

Since travelled 2135 miles in 3.5 hours we have

2135 = 3.5 (x+y) ... i

Similarly with x-y speed it travelled 1855 miles in 3.5 hours

i.e. 1855 =   3.5(x-y) ... ii

Solving these two we can get x and y

i-ii gives

3.5y+3.5y = 2135-1855 = 280

i.e. 7y =280

Or y = 40 mph

Substitute in i

3.5(x+40) = 2135

x+40 = 610

x = 570 mph

Hence the  speed of air in still air= x =570 mph and

speed of wind = 40 mph

To find the speed of the plane in still air and the speed of the wind, set up a system of equations using the given information and solve them simultaneously.

To find the speed of the plane in still air and the speed of the wind, we can set up a system of equations using the given information. Let's call the speed of the plane in still air 'p' and the speed of the wind 'w'.

Given that the plane traveled 2135 miles with the wind in 3.5 hours, we can represent this as p + w = 2135/3.5.

Similarly, given that the plane traveled 1855 miles against the wind in 3.5 hours, we can represent this as p - w = 1855/3.5.

Solving these two equations simultaneously will give us the values of 'p' and 'w'.

Answer:

17 hours and 3 hours.

Step-by-step explanation:

Let us assume that Annie travels x hours and Brian y hours.

Then given that x = 5y+2

Together they travelled = total hours of both = x+y

Substitute x = 5y+2 in the total distance.

We have an equation in a single variable y as

= 5y+y+2 = 20

Simplify to get

6y+2 = 20

subtract 2

6y = 18

Divide by 6

y =3

x =5y+2

= 5(3) +2=17 hours

Annie traveled 17 hours and Brian 5 hours.

Answer:

Cost equation = 5x + 25000

Step-by-step explanation:

Given: The producing the product is 25,000 plus $5.00 per piece.

x is the number of pieces.

Production cost = fixed cost + cost per piece * number of piece.

Given: Fixed cost = $25000 and cost per piece - $5.00

Now plug in these values in the production cost equation.

So, to produce x number of items, the cost = 25000 + 5x

Which can be written as

Cost equation = 5x + 25000

Get the variable alone by doing the same thing to both sides. You will divide 5 by both sides which gets you to 5n/5 = -20/5. You can then cancel out the 5n/5 to get just n. Then find the greatest common factor of the numerator and denominator of -20/5, and then cancel out the GCF.

The answer is n = -4

The solution to the equation 5n = -20 is n = -4.

To solve the equation 5n = -20, you can follow these steps:

Step 1: Divide both sides of the equation by 5 to isolate the variable n.

(5n) / 5 = (-20) / 5

Simplifying the equation gives you:

n = -4

So the solution to the equation 5n = -20 is n = -4.

Answer:

180 tiles.

Step-by-step explanation:

We have been given that Vanessa wants to cover her closet floor with tile’s that are 1/3 feet on each side the closet is 3 1/3 feet wide on a 6 foot deep.

To find the number of tiles needed to cover the closet floor, we will divide area of closet floor by area of each tile as:

[tex]\text{Area of closet floor}=3\frac{1}{3}\text{ feet}\times 6\text{ feet}[/tex]

[tex]\text{Area of closet floor}=\frac{10}{3}\text{ feet}\times 6\text{ feet}[/tex]

[tex]\text{Area of closet floor}=10\text{ feet}\times 2\text{ feet}[/tex]

[tex]\text{Area of closet floor}=20\text{ feet}^2[/tex]

[tex]\text{Area of each tile}=\frac{1}{3}\text{ feet}\times \frac{1}{3}\text{ feet}[/tex]

[tex]\text{Area of each tile}=\frac{1}{9}\text{ feet}^2[/tex]

[tex]\text{Tiles needed to cover the closet floor}=20\text{ feet}^2\div \frac{1}{9}\text{ feet}^2[/tex]

Convert into division problem by flipping the fraction:

[tex]\text{Tiles needed to cover the closet floor}=20\times\frac{9}{1}[/tex]

[tex]\text{Tiles needed to cover the closet floor}=180[/tex]

Therefore, Vanessa needs 180 tiles to cover the closet floor.
