After four hours, the height of the candles will be the same.

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

A red candle has an 8-inch height and burns at a 7/10-inch per hour rate. A 6-inch tall blue candle burns at a rate of 1/5 inch per hour.

Let x be the number of hours and y be the height.

y = -0.70x + 8           ...1

y = -0.20x + 6             ...2

From equations 1 and 2, then we have

- 0.20x + 6 = - 0.70x + 8

(0.70 - 0.20)x = 8 - 6

0.50x = 2

x = 4 hours

After four hours, the height of the candles will be the same.

Answer:

Sorry Bro I can't understand

Answer:

This is true.

Step-by-step explanation:

To prove this as true what we can do is draw a graph. On one of the graphs, we will have a point at (-7,1). If we were going to reflect it over the y-axis by counting the distance it is from the y-axis and counting it in the other direction. When we do this we get a point of (7,1). We can infer that because it was flipped in the y-axis the y value stayed the same while the x-axis changed.

This is how we can prove this to be true.

Answer:

Tom's height = x = 64 inches

Sally's height = y = 60 inches

Step-by-step explanation:

Let us represent

Tom's height = x

Sally's height = y

Tom is 4 inches taller than Sally

x = y + 4

Together their heights equal 124 inches

x + y = 124

We substitute y + 4 for x

y + 4 + y = 124

2y + 4 = 124

Collect like terms

2y = 124 - 4

2y = 120

y = 120/2

y = 60

Solving for x

x = y + 4

x = 60 + 4

x = 64

Therefore,

Tom's height = x = 64 inches

Sally's height = y = 60 inches

The correlation coefficient is 0.9541. This can be determined from the information provided in the ANOVA table, specifically the regression sum of squares (SSR) and the total sum of squares (SST).

The correlation coefficient, also known as the Pearson correlation coefficient, is a measure of the strength and direction of the linear relationship between two variables. It ranges from -1 to 1, where values closer to -1 or 1 indicate a stronger relationship, and values closer to 0 indicate a weaker relationship.

To calculate the correlation coefficient, we can use the formula:

r = sqrt(SSR/SST)

From the ANOVA table provided, we can see that SSR = 12,323.64 and SST = 13,538.4. Plugging these values into the formula gives:

r = sqrt(12,323.64/13,538.4) = 0.9541

Therefore, the correlation coefficient for this model is 0.9541, indicating a strong positive linear relationship between the independent variable and the dependent variable

The probability that a student who has a brother also has a sister is 2/7 or approximately 0.2857.

To find the probability that a student who has a brother also has a sister, we need to use the concept of conditional probability.

Let's first find the probability of a student having both a brother and a sister. According to the problem, there are 2 students who have both a brother and a sister. Therefore, the probability of a student having both a brother and a sister is:

P(Brother and Sister) = 2/23

Now, let's find the probability of a student having a brother:

P(Brother) = 7/23

Using the formula for conditional probability, we can find the probability that a student who has a brother also has a sister:

P(Sister|Brother) = P(Brother and Sister) / P(Brother)

Substituting the values we found, we get:

P(Sister|Brother) = (2/23) / (7/23) = 2/7

This means that if we randomly select a student who has a brother, the probability that they also have a sister is about 0.2857.

the maximum height of a quadratic equation can be find Use the formula: x = -b / (2a) then Substitute the value of x back into the quadratic equation to find the corresponding maximum height.

To find the maximum height of a quadratic equation, you need to determine the vertex of the parabolic curve. The vertex represents the highest or lowest point of the quadratic function, depending on whether it opens upward or downward.

A quadratic equation is generally written in the form of y = ax² + bx + c, where "a," "b," and "c" are coefficients.

The x-coordinate of the vertex can be found using the formula: x = -b / (2a). This formula gives you the line of symmetry of the parabola.

Once you have the x-coordinate of the vertex, substitute it back into the original equation to find the corresponding y-coordinate.

The resulting y-coordinate represents the maximum height (if the parabola opens downward) or the minimum height (if the parabola opens upward) of the quadratic equation.

Here's an example:

Consider the quadratic equation y = 2x² - 4x + 3.

1. Identify the coefficients:

a = 2

b = -4

c = 3

2. Find the x-coordinate of the vertex:

x = -(-4) / (2 * 2) = 4 / 4 = 1

3. Substitute x = 1 back into the equation to find the y-coordinate:

y = 2(1)² - 4(1) + 3 = 2 - 4 + 3 = 1

Therefore, the maximum height of the quadratic equation y = 2x² - 4x + 3 is 1.

The maximum height of a quadratic equation can be found by determining the vertex of the parabolic shape represented by the equation. The x-coordinate of the vertex can be found using the formula x = -b / (2a), and the corresponding y-coordinate represents the maximum height.

To find the maximum height of a quadratic equation, we need to determine the vertex of the parabolic shape represented by the equation. The vertex is the point where the parabola reaches its highest or lowest point.

The general form of a quadratic equation is ax^2 + bx + c, where a, b, and c are constants. To find the x-coordinate of the vertex, we can use the formula x = -b / (2a).

Once we have the x-coordinate, we can substitute it back into the equation to find the corresponding y-coordinate, which represents the maximum or minimum height of the quadratic equation.

Let's take an example to illustrate this process:

Suppose we have the quadratic equation y = 2x^2 + 3x + 1. To find the maximum height, we first need to find the x-coordinate of the vertex.

Using the formula x = -b / (2a), we can substitute the values from our equation: x = -(3) / (2 * 2) = -3/4.

Now, we substitute this x-coordinate back into the equation to find the y-coordinate: y = 2(-3/4)^2 + 3(-3/4) + 1 = 2(9/16) - 9/4 + 1 = 9/8 - 9/4 + 1 = 9/8 - 18/8 + 8/8 = -1/8.

Therefore, the maximum height of the quadratic equation y = 2x^2 + 3x + 1 is -1/8.

The perimeter is 24.56 units and the area is 41.12 square units.

What is perimeter?

Each two-dimensional closed shape's perimeter is defined as the whole distance encircling it. A polygon's perimeter is equal to the sum of its sides.

The given figure is a combination of a semicircle and rectangle.

We are given the diameter as 8 units.

So, the radius is 4 units.

The length of the rectangle is 8 units and breadth is 2 units.

Now,

⇒Perimeter of semi circle = πr

⇒Perimeter of semi circle = 3.14 * 4

⇒Perimeter of semi circle = 12.56 units

Similarly,

⇒Perimeter of rectangle = l + 2b

⇒Perimeter of rectangle = 8 + 4

⇒Perimeter of rectangle = 12 units

So,

⇒Perimeter of shaded figure = 12.56 + 12

⇒Perimeter of shaded figure = 24.56 units

Now,

⇒Area of semi circle = π\(\frac{r^{2}}{2}\)

⇒Area of semi circle = 3.14 * \(\frac{4^{2}}{2}\)

⇒Area of semi circle = 3.14 * 8

⇒Area of semi circle = 25.12 square units

Similarly,

⇒Area of rectangle = lb

⇒Area of rectangle = 8  * 2

⇒Area of rectangle = 16 square units

So,

⇒Area of shaded figure = 25.12 + 16

⇒Area of shaded figure = 41.12 square units

Hence, the perimeter is 24.56 units and the area is 41.12 square units.

Equation: y * 5 = 85

In this equation, 'y' represents the number of learners in class 9T, and '5' represents the number of pencils each learner receives. The equation states that the product of the number of learners (y) and the number of pencils each learner receives (5) is equal to the total number of pencils (85) that Mrs. Leclerc shares among the learners.

This equation can be used to solve for the value of 'y' by dividing both sides of the equation by 5. By doing so, we can determine the number of learners in class 9T based on the given information about the number of pencils shared.

For example, if we divide 85 by 5, the result is 17. Therefore, there are 17 learners in class 9T.

In summary, the equation y * 5 = 85 represents the situation where Mrs. Leclerc shares 85 pencils between the learners in class 9T, with each learner receiving 5 pencils. By solving the equation, we can find the number of learners in the class, which in this case is 17.

The model also assumes that the decision-maker is rational and logical, able to identify and evaluate all alternatives and select the best one based on a careful analysis of the pros and cons of each option.
