Answer:

Please insert a graph.

Step-by-step explanation:

If you submit a picture of the graph on here, I will see how how I can help.

Answer:

(a) x = 2

Step-by-step explanation:

x - 12 = -8x + 6

First, move all the like terms to one side of the equation. We will move all the x's to the left, and the rest to the right in this equation. (Don't forget to pay attention to the signs of the numbers as you move them over the equal sign.)

x - 12 + 8x = 6

x + 8x = 6 + 12

9x = 18

Next, solve for x by isolating it to one side of the equation. Here, we'll have to divide 18 by 9 (do the opposite of what 9 is doing with x; instead of multiplying it with 18 like it currently is with x, divide 18 by it.)

x = \(\frac{18}{9}\)

x = 2

Therefore, your answer is (a), since x = 2.

I hope this helps! I would really appreciate it if you would please mark me brainliest! Have a blessed day!

Developers determine the specifics of how to build a system in the design phase. b

The design phase and its importance:
Define Objectives:

The design phase begins after the completion of the analysis phase, where developers have gathered and evaluated requirements.

The main objective of the design phase is to create a blueprint for the system that addresses all identified requirements.
Create Architectural Design:

During this step, developers establish the overall structure of the system, including its components, their relationships, and the interactions between them.

This architectural design provides a high-level view of the system's organization.
Design System Components:

With the architectural design in place, developers focus on designing individual components or modules of the system. They create detailed specifications, which include the functionality, inputs, outputs, and processes for each component.
Design User Interface:

The user interface design involves creating a user-friendly and efficient way for end-users to interact with the system. This can include designing screen layouts, menus, buttons, and other interface elements.
Validate Design:

The final step in the design phase is to ensure that the proposed design meets all the requirements identified during the analysis phase.

Developers may use various methods, such as reviews and simulations, to validate their design before proceeding to the implementation phase.
The design phase is a crucial part of the system development process, as it defines how the system will be built, ensuring it meets the needs of its users and the project's objectives.

Answer: The base area of the cube is 25 square units.

Step-by-step explanation: A cube has six square faces, all of which are identical. The base area of a cube refers to the area of one of these square faces.

The formula for the volume of a cube is:

V = s^3

where V is the volume of the cube and s is the length of one side of the cube.

If we know the volume of the cube is 125 cubic units, we can solve for the side length:

125 = s^3

Taking the cube root of both sides, we get:

s = 5

Therefore, each side of the cube has a length of 5 units. The area of one of the square faces of the cube is:

A = s^2

A = 5^2

A = 25 square units

So the base area of the cube is 25 square units.

Answer:

25 square units.

Step-by-step explanation:

If a cube has a volume of 125 cubic units, then the edge length of the cube is the cube root of 125:

edge length = ∛125 = 5

Since all sides of a cube are equal, the base of the cube is a square with sides of length 5 units. The area of a square is calculated by multiplying the length of one side by itself:

base area = 5 × 5 = 25 sq. units.

Therefore, the base area of the given cube is 25 square units.

Using equivalent decimals, the correct option regarding which lake lost the least amount of water is:

c. Lake Stockton

For a fraction, we have to divide the numerator by the denominator to find the equivalent decimal.

For a percentage, we just have to divide the percentage by 100%.

Hence, for the three lakes, the equivalent amounts are given by:

Lake Jensen: 1/6 = 0.1666

Lake Parlow: 26% = 26/100 = 0.26

Lake Stockton: 33/200 = 0.165

The smallest equivalent decimal is 0.165,

Hence Lake Stockton lost the least amount of water, and option C is correct.

Answer:

97.5 is 159% of 61.32

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

Let the required number be n.

We are given that 97.5 is 159% of n.

It can be shown as equation:

To find:-

Answer:-

Let us suppose that there's a number " x " , whose 159% is 97.5 .

So we can create a equation as ,

159% of x = 97.5

Write 159% as fraction,

159/100 * x = 97.5

Multiply both sides by 100 ,

159x = 97.5 * 100

Divide both the sides by 159 ,

x = 97.5 * 100 / 159

Simplify,

x ≈ 61.32

Hence 97.5 is 159% of 61.32 .

The statistical term that explains this situation is "Simpson's Paradox." Simpson's Paradox occurs when a trend or association observed in different groups or subsets of data reverses or disappears when the groups are combined.

In this case, the paradox is evident when looking at the performance of schools. Individually, the worst-performing schools met their improvement goals, while some of the supposedly best schools failed to meet their goals. However, when considering the data as a whole, the trend appears to be the opposite of what was observed in the separate groups.

Simpson's Paradox highlights the importance of carefully analyzing and interpreting data, especially when different groups or factors are involved.

The red angle is also greater than 90 degrees but is closer to 90 degrees than the blue angle.

An angle is a geometric figure formed by two rays that share a common endpoint, called the vertex. The rays are called the sides of the angle. Angles are typically measured in degrees or radians, and are denoted using the symbol "∠".

Here the blue angle is greater than 90 degrees, but we need to find an angle that is also greater than 90 degrees and closer to 90 degrees than the blue angle.

Since the blue angle is obtuse (greater than 90 degrees), we need to look for an acute angle (less than 90 degrees) that is closer to 90 degrees than the blue angle.

Looking at the figure, we can see that the red angle appears to be the closest to 90 degrees. The red angle is acute and seems to be closer to 90 degrees than the blue angle.

Therefore, the answer is the red angle.

The probability of drawing a red marble, regardless of the urn chosen, is: (1/6) * (1/100) + (1/6) * (2/5) + (1/6) * (2/5) + (1/6) * (1/2) + (1/6) * (1/2) + (1/6) * (1/2) = 7/30.

In the second part, Bayes' rule is used to determine the probability of drawing from each type of urn given that a red marble was drawn. Using the probabilities calculated earlier, we can apply Bayes' rule:

P(Urn 1|Red) = (P(Red|Urn 1) * P(Urn 1)) / P(Red)

P(Urn 2|Red) = (P(Red|Urn 2) * P(Urn 2)) / P(Red)

P(Urn 3|Red) = (P(Red|Urn 3) * P(Urn 3)) / P(Red)

P(Urn 4|Red) = (P(Red|Urn 4) * P(Urn 4)) / P(Red)

P(Urn 5|Red) = (P(Red|Urn 5) * P(Urn 5)) / P(Red)

P(Urn 6|Red) = (P(Red|Urn 6) * P(Urn 6)) / P(Red)

Substituting the known probabilities, we can calculate the chance of drawing from each type of urn given that a red marble was drawn.

In the last part, if all the marbles are combined into a single urn, the probability of drawing a red marble will be the sum of the red marbles divided by the total number of marbles. This probability can be calculated by adding the red marbles from each urn and dividing by the total number of marbles. However, the probability in part (a) is different from this because it considers the selection of each urn with equal likelihood, whereas in part (c), all marbles are combined into one urn.

just look at the graphic : what value do we have on the cost side, when we have 1 pounds on the amount side ?

all the answer options specify a price per pound. that is why we only need to focus on the price for one pound.

we see in the graphic, that for 1 pound the price is $4.

just to make sure, we can also work with the directly specified point (0.5, 2), which means that 0.5 pounds cost $2.

and the function is clearly a straight line.

so, every point on the function has the same y/x ratio (slope).

therefore,

The area of the top surface of the d) Vanilla cake is 50.24 square inches and the Chocolate cake is 78.5 square inches.

The formula for the area of a circle is π times the radius squared. To find the top surface area of the cakes, we first need to find the radius of each cake by dividing the diameter by 2.

The radius of the vanilla cake is 4 inches and the radius of the chocolate cake is 5 inches. Then, we can use the formula: π times the radius squared to find the area of each cake. Using π = 3.14, we get:

Vanilla cake: π * 4^2 = 50.24 square inches
