Step-by-step explanation:

There are four methods of sampling namely Random sampling,Stratified sampling, Cluster sampling and Multistage sampling. Let’s look at them one by one.

Random sampling - When each subject of the population is equally likely to be included in the sample, the sampling method is called random sampling.

Stratified sampling- Under this, the data are first divided into stratas. Each stratum consists of homogeneous subjects and strata are heterogeneous among themselves. Samples are randomly taken from each strata. Example- In an investigation of mortality rate of the insured, we can first subdivide the data into males and females and then take sample from each group. Here, male and female groups represent stratas.

Cluster sampling- Under this we first divide the data into clusters that are homogeneous among themselves and then select few of them and sample all observations from the randomly selected clusters. For example- suppose we want to take a sample of people's weight in a specific city. We observed that the areas in that city are similar to each other , so instead of travelling to each area and collecting data we can select few areas and then take observations from all people of those areas.

Multistage sampling - This adds one more stage to cluster sampling. Unlike cluster sampling where we sample all observations from the selected clusters, In multistage sampling we randomly sample observations from each selected cluster.

Rounding to the nearest whole number, the tire makes 214 revolutions while traveling 500 feet.

What is Circumference?

Circumference is a term used in geometry to refer to the distance around the edge of a circle or any circular object. It is the total length of the boundary or perimeter of the circle. The circumference is determined by the diameter or radius of the circle, and it is calculated using the formula:

Circumference = π × diameter

The circumference of the tire is equal to the distance it travels in one revolution. Since the diameter of the tire is 28 inches, its radius is 14 inches. Therefore, the circumference of the tire is:

C = 2πr = 2π(14 inches) = 28π inches

To convert the distance of 500 feet to inches, we multiply by the conversion factor 12 inches/foot:

500 feet × 12 inches/foot = 6000 inches

Now we can find the number of revolutions of the tire:

number of revolutions = distance traveled / circumference of tire

number of revolutions = 6000 inches / 28π inches ≈ 214 revolutions

Therefore, rounding to the nearest whole number, the tire makes 214 revolutions while traveling 500 feet.

Ben is incorrect because, all of Ben's expressions are erroneous since none of them equal the number 108 degrees. The correct equation is (n-2) x 180 / n.

A polygon is a geometric shape with a limited number of sides and two dimensions. The sides or edges of a polygon are formed by joining end-to-end segments of a straight line to form a closed shape. The intersection of two line segments, which results in an angle, is referred to as a vertex or corners.

The formula for calculating an interior angle in a regular polygon with n sides is (n-2) x 180 / n.

An internal angle in a pentagon has a measure of (5-2) x 180 / 5 = 108 degrees.

Substituting the angle in Ben's expression:

xᵒ + (x + 40)° + (2x - 30)° + 3(x - 40)° + 3x°

9x - 27° = 108

We observe that none of the value of x results in 108 degrees.

Hence, all of Ben's expressions are erroneous since none of them equal the number 108 degrees.

The other two roots are x = (9 + √137) / 2 and x = (9 - √137) / 2.

Given that x = -9 is a root of |(x,3,7)(2,x,2)(7,6,x)| = 0, we can use the determinant of the matrix to find the other roots. The determinant of the matrix is given by:

| (x,3,7)(2,x,2)(7,6,x) | = x(x*x - 2*6) - 3(2*x - 7*2) + 7(2*6 - 7*x)

= x^3 - 12x - 3(2x - 14) + 7(12 - 7x)

= x^3 - 12x - 6x + 42 + 84 - 49x

= x^3 - 67x + 126 = 0

Since x = -9 is a root, we can divide the polynomial by (x + 9) to get:

(x^3 - 67x + 126) / (x + 9) = x^2 - 9x - 14

Now we can use the quadratic formula to find the other two roots:

x = (-(-9) ± √((-9)^2 - 4(1)(-14))) / (2(1))

x = (9 ± √(81 + 56)) / 2

x = (9 ± √137) / 2

The correct classification for 11+8i is a complex number.√−81 can be expressed as the complex number 9i.

The number 11+8i is a complex number. This is because it has both a real part (11) and an imaginary part (8i). A complex number is any number that can be expressed in the form a+bi, where a and b are real numbers and i is the imaginary unit. Therefore, the correct classification for 11+8i is a complex number.

To express √−81 as a complex number, we can use the fact that √−1 = i. So, √−81 = √(81)*√(−1) = 9*i = 9i. Therefore, √−81 can be expressed as the complex number 9i.

YCG + GCK = 180

YCG = 180- 121

Another method

All the four angles at a point is 360

YCH + HCK + KCG +YCG is 360

C is 121

121 + X + 121 + X = 360

2X + 242 =360

Subract 242 from both sides

2X = 118

An investment of $1,000 at an annual interest rate of 7.5%, compounded annually, will be worth $1,232.28 after 3 years.

Value is a term used to describe the worth of something, either in terms of money, or in terms of importance or usefulness. Value can be determined in terms of the amount of money something is worth, or the level of importance or usefulness it has to someone. When something has a high value, it means that it is worth a lot of money or has a high level of importance or usefulness.

The value of an investment of $1,000 after 3 years at an annual interest rate of 7.5%, compounded annually, can be calculated using the following formula:

Future Value (FV) = Present Value (PV) × (1 + r)ⁿ

Where PV is the present value of the investment ($1,000 in this case), r is the annual interest rate (7.5%) and n is the number of years (3).

Using this formula, we can calculate the future value of the investment after 3 years as follows:

FV = $1,000 × (1 + 0.075)³

FV = $1,000 × 1.23228

FV = $1,232.28

Therefore, an investment of $1,000 at an annual interest rate of 7.5%, compounded annually, will be worth $1,232.28 after 3 years.

To find out how many minutes it would take Teresa to run 9 miles at the same rate, we can use a proportion.

We know that Teresa took 44 minutes to run 6 miles. This means she was running at a rate of 6 miles per 44 minutes. To solve for how long it would take to run 9 miles, we can set up a proportion with this information.

Let x = the number of minutes it would take Teresa to run 9 miles.

6/44 = 9/x

Cross-multiply to solve for x: 44x = 54

Divide both sides by 44 to find the solution: x = 54/44 = 1.227 minutes
