Answer: The total cost of the gas before it was split among the friends.

Explanation: If they split it equally, they divide. 3g is divided by 4 so you know that there are 4 friends/people.

Since they are splitting the [total] amount of gas for 4 people, 3g must be the total cost of the gas.

The mean and standard deviation (in ) of the sampling distribution of the difference in sample means \(\sigma_1\) -  \(\sigma_2\) = (7)² ÷100+ 6² /150.

A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean. Low standard deviation means data are clustered around the mean, and high standard deviation indicates data are more spread out.

Given:

Level A:

S.D. = 7

Level B: Mean = 20

S.D. = 6

So, \(\nu_1\) = 22

\(\nu_2\) = 20

Then,  \(\nu_1\) - \(\nu_2\)   = 22-20=2

and, \(\sigma_1\) -  \(\sigma_2\)

= (7)² ÷100+ 6² /150

Step-by-step explanation:

First, add like terms. You can take out the x if it's too confusing and add it again.

-5/8 - 7/24 + 1/3 (multiply get a common denominator--in this case it's 24)

-15/24 - 7/24 + 8/24

If Point A is located at (1, 2) and Point B is located at (4, 6), the length of the line between points A and B is 5 units.

To determine the length of the line between points A and B, we can use the distance formula, which is a formula used to calculate the distance between two points in a coordinate plane. The distance formula is:

d = √((x₂ - x₁)² + (y₂ - y₁)²)

where (x₁, y₁) and (x₂, y₂) are the coordinates of the two points and d is the distance between them.

Using the coordinates of points A and B, we can substitute their values into the distance formula to find the length of the line between them:

d = √((4 - 1)² + (6 - 2)²)

d = √(3² + 4²)

d = √(9 + 16)

d = √25

d = 5

Rounded to the nearest whole number, the length of the line is also 5 units.

In conclusion, we can use the distance formula to find the length of the line between two points in a coordinate plane. The distance formula uses the coordinates of the two points to calculate the distance between them. The resulting distance can be rounded to the nearest whole number, if needed.

Answer:

below

Step-by-step explanation:

Let's call the number of months since you started the business "x" and the amount of money you make "y". We know two points on this line: (1, $1,200) and (5, $5,800).

From this information, we can write the equation of the line in slope-intercept form: y = mx + b, where m is the slope and b is the y-intercept.

Using the first point, we can solve for b:

$1,200 = m * 1 + b

$1,200 = m + b

b = $1,200 - m

Using the second point, we can solve for m:

$5,800 = m * 5 + $1,200 - m

$5,800 = 6m + $1,200

$4,600 = 5m

m = $920

So the equation of the line is: y = $920x + $1,200

Finally, to find out how much money you will make in 9 months, we can plug in x = 9:

y = $920 * 9 + $1,200

y = $8,280

Therefore, in 9 months, you will make $8,280.

Answer:

Step-by-step explanation:

Lets write a linear equation from two known points

Point 1 = (x1, y1) = (1,1200)

Point 2= (x2,y2)= (5,5800)

The general expression for a linear equation is:

Y-y1 = m (X-x1)

Where:

\(m=\frac{y2-y1}{x2-x1}\)

\(m=\frac{5800-1200}{5-1}\)

\(m=\frac{4600}{4}\)

m= 1150

Therefore, if terms are replaced in the general expression, the linear equation is given by:

Y-1200 = 1150 (X-1)

Y=1150X-1150+1200

Y=1150X+50

Where:

Y= The amount of money you make for the given month

X= Month No.

The equation that represents this situation is 4.75 = 2.5x - 1.25x.

What is a linear equation in one variable?

A linear equation in one variable is an equation that has only one solution and is expressed in the form ax + b = 0, where a and b are two integers and x is a variable. 2x + 3 = 8, for example, is a linear equation with a single variable.

Let the cost of the binder be represented with x.

The cost of the folder is x = 0.5x

The cost of the highlighter = x - $1.25

The total cost of the items = cost of binder + highlighter + folder

                      4.75 = x + 0.5x + x - 1.25

Add similar x terms together, and we get

                         4.75 = 2.5x - 1.25x

Answer:

\(x-3\)

Step-by-step explanation:

The area of the flagpole base is \(x^2-6x+9\ \text{yd}\)

where the factor of the equation is the length of the base.

In order to find the length we need to factorize the equation

\(x^2-6x+9\)

\(=x^2-3x-3x+9\)

\(=x(x-3)-3(x-3)\)

\(=(x-3)(x-3)\)

The length of the base of the flagpole is \((x-3)\ \text{yd}\).

The area of a square base is the product of the side lengths.

The length of the base is x - 3

The area is given as:

\(\mathbf{Area =x^2 - 6x + 9}\)

Expand

\(\mathbf{Area =x^2 - 3x - 3x + 9}\)

Factorize

\(\mathbf{Area =x( x- 3) - 3(x - 3)}\)

Factor out x - 3

\(\mathbf{Area =( x- 3) (x - 3)}\)

Express as squares

\(\mathbf{Area =( x- 3)^2}\)

Rewrite the area as:

\(\mathbf{Length^2 =( x- 3)^2}\)

Take square roots of both sides

\(\mathbf{Length =x- 3}\)

Hence, the length of the base is x - 3

29 years from now, the father will be 49 years old.

Let's start by setting up the given information:

Currently, the father is 20 years old, and the son is 5 years old.

In 10 years, the father will be twice as old as the son.

The father is currently four times as old as the son.

Determine the age of the father and son in 10 years:

In 10 years, the father's age will be 20 + 10 = 30 years.

In 10 years, the son's age will be 5 + 10 = 15 years.

Write equations based on the given information:

The father's age in 10 years will be twice the son's age in 10 years: 30 = 2 × 15.

The father's current age is four times the son's current age: 20 = 4 × 5.

Solve the equations:

From the second equation, we find that the son's current age is 5 years.

Plugging this value into the first equation, we get: 30 = 2 × (5 + 10).

Simplifying further, we have: 30 = 2 × 15, which is true.

Determine the current age of the son in 29 years:

The son's current age is 5 years.

Adding 29 years to the son's current age, we find that the son will be 5 + 29 = 34 years old.

Determine the current age of the father in 29 years:

The father's current age is 20 years.

Adding 29 years to the father's current age, we find that the father will be 20 + 29 = 49 years old.

Therefore, 29 years from now, the father will be 49 years old.

Step-by-step explanation:

From the question given above, the following data were obtained:

Cos α = 0.93

Sine θ = 0.26

Tan β = 0.84

α + β + θ =?

Next, we shall determine the value of α. This can be obtained as follow:

Cos α = 0.93

Take the inverse of Cos

α = Cos¯¹ 0.93

α = 22°

Next, we shall determine the value of θ. This can be obtained as follow:

Sine θ = 0.26

Take the inverse of Sine

θ = Sine¯¹ 0.26

θ = 15°

Next, we shall determine the value of β. This can be obtained as follow:

Tan β = 0.84

Take the inverse of Tan.

β = Tan¯¹ 0.84

β = 40°

Finally, we shall determine the value of α + β + θ . This can be obtained as follow:

α = 22°

θ = 15°

β = 40°

α + β + θ = 22 + 40 + 15

α + β + θ = 77°

If x + 1 is a factor of p(x) = x³ + k x² + x + 6, then by the remainder theorem, we have

p (-1) = (-1)³ + k (-1)² + (-1) + 6 = 0   →   k = -4

So we have

p(x) = x³ - 4x² + x + 6

Dividing p(x) by x + 1 (using whatever method you prefer) gives

p(x) / (x + 1) = x² - 5x + 6

Synthetic division, for instance, might go like this:

-1   |   1    -4     1     6

...   |         -1    5    -6

----------------------------

...   |   1    -5    6     0

Next, we have

x² - 5x + 6 = (x - 3) (x - 2)

so that, in addition to x = -1, the other two zeros of p(x) are x = 3 and x = 2

The number of tiles needed to cover the surface area of the box excluding the bottom is: 1,046 tiles.

The surface area of a box is the area surrounding all its faces. A box has 6 rectangular faces. Therefore, the total surface area of the box equals the sum of all 6 rectangular faces.

SA = 2(lw + lh + hw), where:

The image attached below shows the box Dmitri wants to cover. Since the bottom of the box would be excluded, therefore:

The surface area to be covered = surface area of the box - area of the bottom rectangular face

The surface area to be covered = 2(lw + lh + hw) - (l)(w)

l = 26

w = 15

h = 8

Substitute

The surface area to be covered = 2(l×w + lh + hw) - (l)(w) = 2·(15·26+8·26+8·15) - (26)(15) =

The surface area to be covered = 1436 - 390 = 1,046 cm
