Step-by-step explanation:

Using the Greatest Common Factor, we need to find factor out the greatest common factor of the two numbers ; 24 and 84. That is; the greatest number that can divide 24 and 84

The easiest way to find the greatest common factors is;

1. To first find the factors of each number

2. Find the common factors of the two numbers

3. Find the greatest number among those factors

Factors are number that can divide a number without a remainder.

Factors of 24 are;   1, 2, 3, 6, 8, 12 and 24

Factors  of 84 are; 1, 2, 3, 6, 7, 12, 14, 42 and 84

common factors are the factors that are common between the two numbers. That is; factors we can find in 24 and as well as 84

common factors are;  1, 2, 3, 6, and 12

Greatest Common Factor : This is also known as the highest common factor, it is the highest among the common factors.

Greatest Common Factor is 12.

Now after we've gotten our Greatest Common Factor(GCF), The next is to factor out this Greatest Common Factor(GCF);

24v - 84 =  12(2v - 7)

Therefore, the factored form of 24v - 84 is  12(2v -7)

The factored form of the given expression is 12(2v-7)

Equations are expressions separated by an equal sign

Greatest common factor is the highest value that can go in a particular expressions

Given the expression 24v - 84

Find that factors of both terms

24v = 12 × 2v

84 = 12 × 7

Since 12 is common to both terms, hence the GCF form of the expression will be written as;

24v - 84 = 12(2v - 7)

Hence the factored form of the given expression is 12(2v-7)

Based on the information given regarding the regression line, the correct option is D. That the regression equation is not a good fit for the data.

A regression line simply means a single line that best fits the data. It should be noted that the formula for the regression line is y = mx + b.

Based on the question asked, since the residual plot looks like a quadratic function, it means that the regression equation is not a good fit for the data.

If the regression line is a good fit for the model, there'll be no pattern in the residual. In this case, since there is a residual, it means that the regression equation is not a good fit for the data.

A residual plot showing a quadratic pattern suggests the current linear regression model is inappropriate and a non-linear model might be required. Answer D is correct: the residual plot indicates the regression equation is not a good fit for the data.

When a residual plot exhibits a pattern, such as a quadratic function, this indicates that the regression equation used to fit the data may not be appropriate; specifically, it suggests that a linear model does not properly capture the relationship between the variables. Instead, the underlying relationship may be better modeled with a non-linear equation, such as a quadratic function.

The correct answer to the student's question is D) That the regression equation is not a good fit for the data.

A good residual plot will have residuals scattered randomly around the horizontal axis, which means that the regression model adequately captures the pattern in the data.

Final answer:

The total trip cost, including gas, hotel, and food for three people, is $829.70, calculated by multiplying the quantities by their respective unit prices and summing up all costs.

Explanation:

Calculating the Total Trip Cost

To calculate the total cost of the trip, we need to consider the cost of gas, hotel, and food. For gas, the cost is $2.09 per gallon, and the consumption is 30 gallons. The hotel cost is $98 per night for 4 nights. Each person's food cost is $25 per day for 5 days.

Here is the detailed calculation:

Therefore, the total cost of the trip is $829.70.

The total cost of the trip is $705.70.the total cost of the trip amounts to $705.70. This includes various expenses such as gas for the trip calculated at $62.70, hotel expenses totaling $392 for the four-night stay, and food expenses adding up to $375 for three people over five days.

To calculate the total cost, start with the gas cost: 30 gallons * $2.09/gallon = $62.70. Next, calculate the hotel expenses: 4 nights * $98/night = $392. Then, calculate the food expenses: 3 people * $25/day * 5 days = $375. Add all these expenses together: $62.70 (gas) + $392 (hotel) + $375 (food) = $829.70.

However, to account for the cost shared among friends, divide the total by 3: $829.70 / 3 = $276.57 per person. Finally, multiply the individual cost by 3 people to find the total cost: $276.57/person * 3 people = $829.70. The final total cost of the trip, considering shared expenses, is $705.70. This includes gas, hotel accommodation, and food for three individuals across the entire trip duration.

In summary, the total cost of the trip amounts to $705.70. This includes various expenses such as gas for the trip calculated at $62.70, hotel expenses totaling $392 for the four-night stay, and food expenses adding up to $375 for three people over five days.

The calculation incorporates sharing costs among the three friends, dividing the overall expenses equally. Each individual's share amounts to $276.57, resulting in a final total cost of $705.70 for the entire trip. This comprehensive calculation considers all major expenses incurred during the trip and divides the shared costs among the friends, arriving at the total trip expenditure.

Answer:

y = 3x - 5

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y-intercept )

y = - [tex]\frac{1}{3}[/tex] x + 1 is in this form

with slope m = - [tex]\frac{1}{3}[/tex]

given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-1/3}[/tex] = 3

y = 3x + c ← is the partial equation

to find c substitute (3, 4) into the partial equation

4 = 9 + c ⇒ c = 4 - 9 = - 5

y = 3x - 5 ← equation of perpendicular line

Final answer:

By inserting parentheses to create the expression (6 + 10) x 2, we change the order of operations and get the desired result, which is 32.

Explanation:

The question involves inserting parentheses in the expression 6 + 10 x 2 so that the result of the expression equals 32. According to the order of operations, we typically perform multiplication before addition, so if we compute the expression as it stands, we would get 6 + (10 x 2) = 6 + 20 = 26, which is not the result we want. To achieve the desired result, we need to adjust this order. By adding parentheses, we can change the order in which the operations are performed. Thus, the correct placement of parentheses would be (6 + 10) x 2, which gives us (16) x 2 = 32.

Use the slope formula

m = (y2 - y1)/(x2 - x1)

m = (2 - 5)/(-23 - (-8))

m = (2 - 5)/(-23 + 8)

m = (-3)/(-15)

m = 1/5

m = 0.2

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

The answer as a fraction is 1/5

In decimal form, this is equivalent to 0.2

To find the slope, use the slope formula and plug in the two points:

(-8,5) = (x₁ , y₁)

(-23,2) = (x₂ , y₂)

[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

[tex]m=\frac{2-5}{-23-(-8)}[/tex]

[tex]m=\frac{2-5}{-23+8}[/tex]

[tex]m=\frac{-3}{-15}[/tex]

[tex]m=\frac{1}{5}[/tex]

Let the slower runners speed be X kilometers per hour.

Then the faster runners speed would be X+2 kilometers per hour.

The formula for distance is Speed times time.

The distance is given as 30 kilometers and time is given as 3 hours.

Since there are two runners you need to add the both of them together.

The equation becomes 30 = 3x + 3(x+2)

Now solve for x:

30 = 3x + 3(x+2)

Simplify:

30 = 3x + 3x +6

30 = 6x + 6

Subtract 6 from each side:

24 = 6x

Divide both sides by 6:

x = 24/6

x = 4

The slower runner ran at 4 kilometers per hour.

The faster runner ran at 4+2 = 6 kilometers per hour.

Answer:

The value of k is -5.

Step-by-step explanation:

To find the value of k, start by using the known information we have in the equation for slope. The equation is below.

m(slope) = (y2 - y1)/(x2 - x1)

In this equation, the first ordered pair would be (x1, y1) and the second would be (x2 , y2). So we put the values in for these variables and we get.

-1/5 = (-7 - k)/(6 + 4)

-1/5 = (-7 - k)/10

Now we can use cross multiplication to solve for k.

-1/5 = (-7 - k)/10

-1*10 = 5(-7 - k)

-10 = -35 - 5k

25 = -5k

-5 = k

Answer:

k=-5

Step-by-step explanation:

To find the value of k, start by using the known information we have in the equation for slope. The equation is below.

m(slope) = (y2 - y1)/(x2 - x1)

In this equation, the first ordered pair would be (x1, y1) and the second would be (x2 , y2). So we put the values in for these variables and we get.

-1/5 = (-7 - k)/(6 + 4)

-1/5 = (-7 - k)/10

-1/5 = (-7 - k)/10

-1*10 = 5(-7 - k)

-10 = -35 - 5k

25 = -5k

-5 = k

Final answer:

By setting up a proportion based on the fact that 4 ounces represents 25% of the amount in bottle B, we calculated that bottle B must contain 16 ounces of water.

Explanation:

The question asks us to determine how much water is in bottle B given that bottle A contains 4 ounces of water, which is 25% of the amount of water in bottle B. This means bottle A has one-fourth the amount of water that is in bottle B.

To find out how much water is in bottle B, we can set up a simple proportion: if 4 ounces is 25%, then 100% (which is the full amount in bottle B) would be four times as much. Therefore, we multiply 4 ounces by 4.

4 ounces × 4 = 16 ounces

So, bottle B contains 16 ounces of water.

The area of the blue glass needed to fill each dot is 144π square inches.

To find the area of the blue glass needed to fill each dot, we need to first determine the radius of the dot. The distance around each dot is given as 24π inches, which means the circumference of the dot is 24π inches.

Using the formula for circumference, 2πr = 24π, we can solve for the radius r, which is 12 inches. The area of the blue glass needed to fill each dot is then the area of a circle with radius 12 inches, which is given by the formula A = πr^2.

Substituting the value for r, we get A = π(12)^2 = 144π square inches.

Your y intercept is your c value. Your c value is 4.

4 is your y intercept.

Place a point on 4. This is your starting point. Rise over run is 1/1

To find the positive points, go up one from the y intercept and over one, repeating the process until you reach the edge of the graph.

To find the negative points, do the opposite. Go down one and to the left, but still repeat the process until you reach the end of the graph.

Linear equations are always ended with arrows on both sides, meaning that the line continues forever, or infinitely.

To find domain, look at the x values.

Because the lines go on infinitely, you know that your domain is (-infinity, infinity).

To find your range, look at your y values.

Because the lines go on infinitely, you know that your range is also (-infinity, infinity).

Make sure to use the symbol for infinity instead of the words. In case you do not know what the infinity symbol is, it simply looks like an 8 that is rotated 90 degrees.
