When a study uses random sampling, each member of a population has an equal chance of being selected.

Cluster sampling occurs when researchers randomly sample subsets of the population and then use all individuals within the subsets.

Oversampling is often used to select participants to represent, in an unbiased way, subsets of the population that are not large enough to be accurately measured.

All all three of these techniques are representative sampling techniques.

It should be noted that sampling simply means the selection of subjects from the entire population.

In a random sampling, everyone has equal opportunity of being picked.

The answer to the given notation is 1970

Any value between 1.0 and 10.0 that can be expressed as a decimal number and multiplied by a power of 10 is referred to as being in standard form. If you look closely, you will see that 1.23 is a decimal between 1.0 and 10.0, and as a result, we have the standard form of 123,000,000 as 1.23 108.

This is already an standard notation : 1.97 × 10³

10 raised to the power three means there are three zeroes.

thus if we were to solve this question it will be

1.97 × 1000

which is equal to 1970.00

= 1970 .

Answer: 26 inches

Step-by-step explanation:

An isosceles triangle has two congruent legs.

1) Set up the equations

P = b + 2L

b = 2L-6

2) Substitute for variables

46 = (2L - 6) + 2L

3) Solve the equation

46 = 4L - 6

52 = 4L

13 = L

4) Solve the problem

It asks for what is the sum of the two congruent legs

13 + 13 = Ans

26 = Ans

Answer:

1. m∠P + m∠Q + m∠R = 180°

2. x = 10

Step-by-step explanation:

By the triangle sum theorem, the sum of the angles in a triangle is 180°. Therefore, using the given sum theorem, m∠P + m∠Q + m∠R = 180°. Using the substitution property, (5x)° + (5x)° + (8x)° = 180°. Simplifying the equation gets 18x = 180°. Finally, using the division property of equality, x = 10.

The arrival rate is found to be 30 emails per hour and the service rate is calculated to be 45 emails per hour.

It has been mentioned in the question that in every 2 minutes, customers send emails to a help desk of an online retailer, on an average, and the standard deviation of the inter-arrival time is also given to be 2 minutes. The online retailer has three employees for answering those emails.

It takes almost 4 minutes to write a response email to the customer, on average. The standard deviation (SD) of the service times is 2 minutes. This is a g/g/k type queue.

Therefore the arrival rate per hour is given by the following relation:

Arrival rate in 1 hr = No. of minutes in an hr / inter arrival time of email taken in minutes

Given here,

No. of minutes in an hour = 60 minutes

Inter arrival time of the email taken in minutes = 2 minutes

∴ Arrival rate in 1 hr = 60 / 2

                                = 30 emails / hr

Hence the arrival rate is 30 emails per hour.

Now for finding out the service rate we have the following formula:

Service rate = No. of minutes in an hr x No. of employes answering/ average time that is required to write response email

Given here,

No. of minutes in an hr = 60 minutes

No. of employes answering = 3

Average time that for writing response email = 2 minutes

∴ Service rate = 60 * 3 / 4

                       = 45 emails / hr

Hence the service rate is 45 emails per hour.

Step-by-step explanation:

Two or more expressions with an equal sign is called as Equation. We solve the problem by forming equations, After solving equations we came to know that 123 hotdogs were sold in the concession stand.

Two or more expressions with an equal sign is called as Equation.

Given that,

A concession stand sells drinks and hotdogs.

The number of drinks sold is 5 more than 4 times the number of hotdogs sold.

The stand sold 500 items.

Let the number of hotdogs=x

The number of drinks sold is 5 more than 4 times the number of hotdogs sold.

The number of drinks=5+4x

stand sold 500 items.

Let us formulate a equation by given data

5+4x=500

Let us separate the variable x on one side.

Subtract 5 on both sides

5+4x-5=500-5

4x=500-5

4x=495

Divide both sides by 4

x=123.25

Hence 123 hotdogs were sold in the concession stand.

The total cost of the skateboard after being discounted by 12% and then sales tax of 6.75% is$74.22.

The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.

As per the given,

Usually, the price of the skateboard = $79.01

The 12% of 79.01 ⇒ (12/100)79.01 = $9.4812

The price after a 12% discount

79.01 - 9.4812 = $69.5288

The 6.75% of 69.5288 ⇒(6.75/100)69.5288 = $4.693194

The total price after applying the 6.75% tax,

$69.5288 + $4.693194 = $74.22

Hence "The total cost of the skateboard after being discounted by 12% and then sales tax of 6.75% is$74.22".

Answer:

  1,225,043

Step-by-step explanation:

You want the ratio of volumes of spheres 428 inches and 4 inches in diameter.

The volume of a sphere in terms of its diameter is ...

  V = (π/6)d³

The ratio of the volumes of the larger to smaller sphere is ...

  [tex]\dfrac{V_{large}}{V_{small}}=\dfrac{\pi/6\cdot428^3}{\pi/6\cdot4^3}=\left(\dfrac{428}{4}\right)^3=107^3=\boxed{1,\!225,\!043}[/tex]

The ratio of volumes is 1,225,043.

The ratio of the volume of the large sphere to the volume of the small sphere is 1225043:1

The following is the formula for finding the volume of a sphere:

V = [tex]\frac{4}{3} \pi r^3[/tex]

Now, the normal assumption is that we must use the formula to calculate the volume of both spheres in order to compare. However, observe that in comparing the volume of two different spheres, the only difference between them is the radius, thus we can compare the two spheres directly in this way:

[tex]\frac{(radius of sphere B)^3 }{(radius of sphere A)^3}[/tex]

So,

[tex](\frac{428}{4})^3[/tex]

[tex]107^3[/tex]:1

Answer:

5/3 is the slope. slope is the same thing as rate of change

Step-by-step explanation:

The slope and intercept of the line are -2 and 0. The equation of the line is y = -2x

To find the equation of line, we have to find the slope of the equation and its y-intercept.

The slope of a line can be calculated as

[tex]m = \frac{y_2 - y_1}{x_2 - x_1} \\m = \frac{-4 - (-4)}{6 - 2}\\m = \frac{-8}{4} \\m = -2[/tex]

The slope of the line is equal to -2.

Lets find the intercept of the line;

The line of an equation is given as

[tex]y = mx + c[/tex]

We can pick point A and substitute its values to find c

[tex]y = mx + c\\- 4 = -2(2) + c\\-4 = -4 + c\\c = -4 + 4\\c = 0[/tex]
