The type of sampling method in which a sample frame is divided into groups is called stratified sampling.

The sampling method that describes the division of a sample frame into groups is called cluster sampling. This method involves randomly selecting groups (or clusters) from the population and then selecting individuals within those clusters to be part of the sample. It is different from stratified sampling, which involves dividing the population into subgroups and then randomly selecting individuals from each subgroup, and simple random sampling, which involves randomly selecting individuals from the population without any grouping. Systematic sampling involves selecting every nth individual from a list of the population.

The required function is P(t)=50000 + 5000t.

In this problem we need to form the function of the population in a town.

Here it is given that the initial population of the town is 50000.

the rate at which the population increases is 5000 per year.

So, the increase for the first year will be 5000. And the population will be 55000.

Then again for the next year the growth will be 5000 and the population will be 50000 + (5000×2)

        = 60000

So we can see clearly that the population is varying with time and we can write the function as P(t)=50000 + 5000t where t is the time in years.

Answer:

Step-by-step explanation:

MN = 89

ON = 39

MO = 80

You can draw your own diagram. Start with the right angle at O. No just label one end (other than O) equal to M. Label the other end of the right angle as N. Don't worry it doesn't look right. All will come out in the wash when you do the ratios.

Join MN

MN is the hypotenuse. Label it as 89 somewhere near the middle.

ON is 39 and MO is 80.

Now you want the Tangent of <M.

Tangent of M = Opposite / Adjacent. You have to actually do this. The opposite side of <M is the one that does not contain the letter M. It is NO.

The adjacent side is not the hypotenuse and does contain the letter M. It is OM

opposite = NO = 39

opposite = MO = 80

Tan<M = 39/80 = 0.4875

I really suggest you go through all the steps. You will a lot by doing it.

Answer:

c. 12 pens and 15 pencils

Step-by-step explanation:

We can find the number of each box Denis bought using a system of equations.

Let x represent the number of pen boxes and y the number of pencil boxes Denis bought

First equation:

We know that the sum of the quantities of the pen and pencil boxes equals the total number of boxes altogether as

# of pen boxes + # of pencil boxes = total number of boxes

x + y = 27

Second equation:

We know that the sum of the costs of the pen and pencil boxes equals the total cost as

(price of pen boxes * # of pen boxes) + (price of pencil boxes * # of pencil boxes) = total cost

15x + 18y = 450

Method to solve:  Substitution:

We can isolate x in the first equation and plug it in for x in the second equation.  This will allow us to first find y:

(x + y = 27) - y

x = -y + 27

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

15(-y + 27) + 18y = 450

-15y +405 + 18y = 450

3y + 405 = 450

3y = 45

y = 15

Find x:

Now we can find x by plugging in 15 for y in x + y = 27:

x + 15 = 27

x = 12

Thus, Denis bought 15 pens and 12 pencils (answer choice c.)

Check work:

We can check our work by plugging in 15 for y and 12 for x in both equations and seeing if we get 27 for the first equation and 450 for the second equation:

Checking solutions in x + y = 27:

12 + 15 = 27

27 = 27

Checking solutions in 15(12) + 18(15) = 450

15(12) + 18(15) = 450

180 + 270 + 450

450 = 450

Thus, our answers are correct.

Answer:

Marius is right.

Step-by-step explanation:

So although what Khalil said could be correct, they didn't say it right. It would be any two numbers the same distance from 0 going the opposite ways, which means that if you had 3 on one side, you would have -3 on the other side. BUt since Khalil said it wrong, he's basically saying that you can do 3+3 because they're both the same distance away from 0. or you could do (-3)+(-3)=-6 which would still work because they're the same distance away from 0. So unless you just skipped on that part while typing the question, Marius is correct.

Below are some authorial techniques that can be used to create mystery, tension, or surprise in literature.

Order of events: The order in which events are presented can create a sense of mystery or suspense.

Pacing: The pace of a story can also be used to create suspense. A slow-paced story can build tension by allowing the reader to dwell on the details of a situation, while a fast-paced story can create excitement and surprise by keeping the reader guessing what will happen next.

Structure: The structure of a story can also be used to create mystery, tension, or surprise. For example, a story that is told in flashback can create a sense of mystery by revealing information about the past that is relevant to the present.

Time manipulation: The manipulation of time can also be used to create suspense.

Language: The language that an author uses can also be used to create mystery, tension, or surprise. For example, an author might use vague or ambiguous language to create a sense of mystery, or use strong language to create a sense of tension or surprise.

Yes, 2/5 times x  always represent 40 percent of that number.

A percentage is a way of expressing a portion or fraction of a whole as a quantity out of 100. It is represented by the symbol "%". For example, 25% is equivalent to 25 out of 100, or 0.25 as a decimal

To convert a fraction to a percentage, you need to multiply it by 100. So, 2/5 times x can be written as:

(2/5) x 100% = 40% of x

So, when x represents a number, then 2/5 times x will represent exactly 40% of that number.

 For example, if x=7, then 2/5 times x is (2/5) x 7 = 2.8, which is exactly 40% of 7 (which is 2.8/7 = 40/100 = 0.4 or 40%).

So, in general, 2/5 times x will represent 40% of x .

The idea of the Laffer Curve, as it is expressed mathematically, is that there is an optimal tax rate at which the government can maximize revenue. This concept is based on the idea that as tax rates increase, revenue collected by the government initially increases but eventually reaches a point at which further increases in tax rates lead to a decrease in revenue.

The Laffer Curve is used to analyze how economic policies may affect growth and stability by illustrating the trade-off between higher tax rates and revenue generation. It is often used as an argument to reduce the government's role in the economy, as increasing taxes beyond a certain point can be counterproductive.

Additionally, the Laffer Curve is related to the idea that aggregate supply increases when production costs decrease, as lower taxes can lead to lower production costs and, therefore, an increase in supply. This is a long answer that describes the various aspects of the Laffer Curve.

The statement " An example of continuous data would be the numbers on baseball player jerseys" is false because the numbers on baseball player jerseys represent a finite set of distinct values, which makes them an example of discrete data, not continuous data.

Continuous data is data that can take on any value within a range or interval. This means that the data can be measured and expressed as a decimal or a fraction, and there are an infinite number of possible values within the range. For example, the height of a person can be any value between 5 feet and 6 feet, including all the possible fractions or decimals in between.

On the other hand, discrete data is data that can only take on certain distinct values. These values cannot be measured or expressed as a decimal or a fraction. Examples of discrete data include the number of children in a family, the number of students in a classroom, or the number of books on a shelf.

In the case of baseball player jerseys, the numbers are assigned to players based on a finite set of integers (typically 0 to 99), and there are no fractional or decimal values in between. Therefore, the numbers on baseball player jerseys are an example of discrete data, not continuous data.

A cycloid is the plane curve traced out by a point on the circumference of a circle as it rolls without slipping along a straight line.

A cycloid is a geometric curve that occurs when a point on the circumference of a circle rolls along a straight line without slipping. As the circle rolls, the point traces a curve in the plane known as a cycloid.

To understand how a cycloid is formed, imagine a circle with a fixed radius rolling along a straight line. As the circle rolls, a point on its circumference, called the generating point, moves along the line, tracing out a curve.

The resulting curve has distinct characteristics. It consists of a series of arcs, with each arc representing one revolution of the rolling circle. The shape of the curve depends on the size of the rolling circle and the path it follows.

The equation that describes a cycloid is parametrically defined by two equations: one for the x-coordinate and one for the y-coordinate of the generating point. These equations involve the radius of the rolling circle, the angular displacement, and the position of the starting point.

Cycloids have been studied for their mathematical properties and applications in various fields, including physics, engineering, and mathematics. They have intriguing properties such as cusps, where the curve has a sharp corner, and self-intersections, where different parts of the curve overlap.

The study of cycloids has practical implications, such as in designing gear systems and understanding the motion of objects rolling along surfaces. They also have aesthetic appeal and have been used in architecture and art.

In summary, a cycloid is a curve formed by a point on the circumference of a circle as it rolls without slipping along a straight line. It is a fascinating geometric shape with various applications and mathematical properties.

The sample size used in this analysis, representing the number of sales calls Lori made during the month, is approximately 385.

The sample size used in this analysis, representing the number of sales calls Lori made during the month, can be determined using the standard error of the proportion and the desired level of confidence.

To calculate the sample size, we need to use the formula:

\(n = (Z^2 * p * (1 - p)) / E^2\)

Where:

n = sample size

Z = z-score corresponding to the desired level of confidence

p = estimated proportion (historical book adoption rate)

E = margin of error (standard error of the proportion)

Given the standard error of the proportion as 0.0400, we can use this value as the margin of error (E). Assuming a 95% level of confidence, the corresponding z-score is approximately 1.96.

Plugging these values into the formula, we have:

n = (1.96^2 * 0.20 * (1 - 0.20)) / 0.0400^2

Simplifying the equation, we get:

n = (3.8416 * 0.20 * 0.80) / 0.0016

n = 0.61536 / 0.0016

n ≈ 384.6

Therefore, the sample size used in this analysis, representing the number of sales calls Lori made during the month, is approximately 385.

The coordinates of the top right corner of the screen (1280, 720).

The coordinates usually consist of two or three values, depending on whether you're working with a two-dimensional or three-dimensional system.

To answer your question, we need to know which coordinate system we're using. In this case, we're assuming that we're dealing with a two-dimensional system, which means that we only need to specify two coordinates: the x-coordinate and the y-coordinate.

The top right corner of the screen is located at a specific position that can be determined by measuring the distance from the origin (usually the bottom left corner) to that point. If we assume that the origin is located at (0, 0), then we need to find the x and y values that correspond to the top right corner.

The x-coordinate of the top right corner depends on the width of the screen, which can vary depending on the device you're using. For example, if the width of the screen is 1280 pixels, then the x-coordinate of the top right corner would be 1280.

The y-coordinate of the top right corner also depends on the height of the screen, which again can vary depending on the device. If the height of the screen is 720 pixels, then the y-coordinate of the top right corner would be 720.

Therefore, the resulting coordinates would be (1280, 720).

Answer:

She will be paid $1,350

Step-by-step explanation:

Let the flat rate be $x and the fixed percentage be y% = y/100

Thus, her payment per month will be

x + (y% of monthly amount) = Payment

For the 1st month, her pay calculations will look like this;

x + y/100 *(16,000) = 1,600

x + 160y = 1600 •••••••••(i)

For the month before the last, her calculations would be;

x + y/100(12,000) = 1,400

x + 120y = 1,400 ••••••••(ii)

It is these two equations that we now solve simultaneously.

We can directly get this by subtracting equation ii from i

That would be;

(x-x) + (160y-120y) = (1600-1400)

40y = 200

y = 200/40

y = 5%

To get x, we can substitute in any of the equations

Let us use equation ii

x + 120(5) = 1,400

x + 600 = 1,400

x = 1,400-600

x = $800

Thus, for $11,000 , the equation will be as follows;

x + (y% of amount) = payment

= $800 + (5/100 * 11,000) = $800 + $550 = $1,350
