Answer:

294

Step-by-step explanation:

To find the surface area of a cube, first we need to realize that a cube, on its surface, is made up of 6 squares forming a box. That means that all we need to do is find the surface area of one of those squares, and multiply it by 6. So what we do is take side length 7, and square it, giving us 49. Then, we multiply that by 6 giving us 294. The formula for this, in short, is y=6a^2, y being the total surface area and a being a side length, in this case 7.

Option (a) is correct. There'll be No Solution to the given system of linear equations.

According to the solutions of linear equations, we know the following things,
1. If two intersecting lines are at one common point, the system has only one solution.
2. If two coincidental lines mean both equations give the same line, that means the system has infinitely many solutions.
3. If the lines are parallel to each other, the system will have no solution.

We can see lines are parallel but we can also find whether the given lines are parallel or not by simply finding their slope m.

For Line 1, we have the following data
\($\left(\mathrm{x}_1, \mathrm{y}_1\right)=(0,2)$\)

\($\left(\mathrm{x}_2, \mathrm{y}_2\right)=(3,1)$\)

For slope m of the line 1,
slope m₁ = \(\frac{y_2-y_1}{x_2-x_1}=\frac{1-2}{3-0}=-\frac{1}{3}\)

For Line 2, we have the following data

\($\left(\mathrm{x}_1, \mathrm{y}_1\right)=(0,-1)$\)

\(- $\left(x_2, y_2\right)=(3,-2)$\)

For slope m of line 2,
slope m₂\($=\frac{y_2-y_1}{x_2-x_1}=\frac{-2-(-1)}{3-0-x_1}=-\frac{1}{3}$\)

As the slope of both lines is equal, so lines are parallel to each other, and hence, if lines are parallel so there'll be no solution to the system.
Hence, option (a) is correct.

Using z - score the minimum score required for the scholarship is 31.8

Since ACT Reading scores are normally distributed with a mean of 21.3 and a standard deviation of 6. Since a university plans to award scholarships to students whose scores are in the top 4%. To find the minimum score required, we use the z-score.

Z-score is a statistical measurement that describes a value's relationship to the mean of a group of values. Z-score is measured in terms of standard deviations from the mean. It is given by

z = (x - μ)/σ where

Since we require x, making x subject of th formula, we have

x = σz + μ

Since  ACT Reading scores are normally distributed with a mean of 21.3 and a standard deviation of 6. Since a university plans to award scholarships to students whose scores are in the top 4%, we have that

For the minimum score p value = 4% which is in the 100 - 4 = 96 percentile.

So, the p value , p = 0.96. Thus the z-score z = 1.75

So, substituting these into the equation for x , we have

x = σz + μ

x = 6 × 1.75 + 21.3

x = 10.5 + 21.3

x = 31.8

So, the minimum score is 31.8

Here we have given that a radio station claims that the amount of advertising each hour has a mean of 12 minutes and a standard deviation of 1.5 minutes. you listen to the radio station for 1 hour and observe that the amount of advertising time is 5 minutes.

And we need to calculate the z-score for this amount of advertising time.

While we looking into the given question, we have identified that Z-scores measure the distance of any data point from the mean in units of standard deviations and are useful because they allow us to compare the relative positions of data values in different samples.

Here the z-score for any single data value can be found by the formula:

z = (data value- mean) / standard deviation

Here from the information given we know:

Data value = 11 minutes

Mean = 12 minutes

Standard deviation = 1.5 minutes

When we apply the values on the formula then we get,

The mouse traveled 4 meters while pushing the block of cheese with 4 N of force if she did 16 J of work.

An equation is a mathematical statement that shows that two expressions are equal. Equations typically consist of variables, constants, and mathematical operations such as addition, subtraction, multiplication, and division.

We know that work (W) is equal to force (F) times distance (d) in the direction of the force, so we can use the formula:

W = F x d

To find the distance traveled (d), we need to rearrange the formula:

d = W / F

Plugging in the values we have:

d = 16 J / 4 N

d = 4 meters

Therefore, the mouse traveled 4 meters while pushing the block of cheese with 4 N of force, if she did 16 J of work.

Kyle's estimate of 9 was not very accurate, but his calculated answer of 9 1/24 is a reasonable approximation of the sum.

To determine if Kyle's calculated answer is reasonable, we can compare it to the original sum of 3 1/6 + 5 7/8.

First, we need to convert the mixed numbers to improper fractions:

3 1/6 = 19/6

5 7/8 = 47/8

Next, we can add the fractions:

19/6 + 47/8 = (152 + 141)/48 = 293/48

Now, we can compare this exact sum to Kyle's estimated answer of 9 and his calculated answer of 9 1/24.

Kyle's estimated answer of 9 is much larger than the exact sum of 6 5/48.

The coordinates of B' after the translation represented by (x - 4, y - 3) is (1, -2). See other solutions below

B is located at the point (5, 1) in the figure.

If we translate the point by (x - 4, y - 3), the new location of B, denoted by B', can be found by subtracting 4 from the x-coordinate and 3 from the y-coordinate.

Therefore, B' is located at (1, -2).

The given information provides us with a set of matching points, which are:

Preimage = (2, 1)

Image = (-1, 2)

These points can be represented by the equation:

(x, y) = (-y, x)

This equation indicates that the points have undergone a (d) clockwise rotation of 270 degrees.

Here, the smaller shape is created by scaling down a larger shape, the transformation is a dilation that results in a reduction.

The scale factor for this transformation could be either 1/2 or 1/4.

Given the points P = (3, -2) and S = (4, -5), we apply two transformations.

The first transformation (x - 2, y) is defined as shifting the x-coordinate of each point left by 2 units, while keeping the y-coordinate the same.

This results in new points P' = (1, -2) and S' = (2, -5).

The second transformation involves reflecting the new points across the x-axis, which changes the sign of their y-coordinates.

The resulting points are P'' = (1, 2) and S'' = (2, 5).

In this context, we are given the coordinates of point A as (-2, -5).

This implies that if we scale down the original coordinates by a factor of 1/2, we get the new coordinates of point A, which become (-1, -2.5).

Therefore, the coordinates of point A' are (-1, -2.5).

An expert system differs from conventional systems in that it incorporates knowledge and expertise in a specific domain to make intelligent decisions or provide recommendations.

Conventional systems are typically rule-based or algorithmic, where predefined rules or instructions are followed to process data or perform tasks. These systems are designed to handle specific functions but lack the ability to mimic human expertise or reasoning.

On the other hand, an expert system utilizes artificial intelligence (AI) techniques, such as knowledge representation, inference engines, and learning algorithms, to capture and apply human expertise in a particular domain. It relies on a knowledge base, which contains expert knowledge and rules, and an inference engine, which uses logical reasoning to draw conclusions or provide recommendations based on the given input.

The key distinction of an expert system lies in its ability to handle complex, knowledge-intensive tasks that would typically require human expertise. By emulating the decision-making processes of human experts, expert systems can analyze complex data, diagnose problems, offer solutions, and provide expert-level advice.

Expert systems have applications in various fields, including medicine, finance, engineering, and customer support. They enable organizations to leverage and preserve expert knowledge, enhance decision-making processes, and improve overall efficiency and accuracy.

In summary, expert systems differ from conventional systems by incorporating AI techniques to emulate human expertise, allowing them to handle complex tasks and provide intelligent recommendations.

Step-by-step explanation:

The area of the 1/4 inch diameter circle, expressed to the nearest thousandth square inch, is 0.049 square inches.

The formula to find the area of a circle is A = π\(r^2\).

Where,

r is the radius of the circle.

Since the diameter of the circle is given as 1/4 inch, the radius is 1/8 inch (radius = diameter/2).
Substituting the value of r in the formula, we get A = π(1/8) = π/64 square inches.
Now, to express the answer to the nearest thousandth square inch, we need to calculate the value of π/64 and round it to the nearest thousandth. Using a calculator, we get π/64 = 0.04908738521...
The area of a circle with a 1/4 inch diameter, we'll use the formula A = π\(r^2\), where A is the area, and r is the radius.

First, we need to find the radius.

Since the diameter is 1/4 inch, the radius (r) is half of that: 1/8 inch.

Now, we'll calculate the area: A = π\(\frac {1}{8} ^{2}\) = π(1/64) ≈ 0.0123 square inches. So, the area of the circle is approximately 0.0123 square inches to the nearest thousandth.
Rounding this value to the nearest thousandth gives us 0.049 square inches.
