Answer:

convenience sampling is the correct answer.

Step-by-step explanation:

A convenience sample is a type of non-probability sampling method where the sample is taken from a group of people easy to contact or to reach.

<u>For example: </u> standing at a mall or a grocery store and asking people to answer questions would be an example of a convenience sample.

This type of sampling is also known as grab sampling or availability sampling. There are no other criteria to the sampling method except that people be available and willing to participate.

In addition, this type of sampling method does not require that a simple Random sample is generated, since the only criteria is whether the participants agree to participate.

1) The x-axis represents the energy (E), in joules. The y-axis represents the amplitude (x), in milimeters.

2) The curve depicts an <em>monotonous decrecent</em> rate of change.

3) The amplitude is directly proportional to the root square of the energy.

<h3>How to analyze a graph relationship between two variables</h3>

In this question we have a relationship between two variables, in which we must apply principles of <em>functional</em> analysis to respond three questions presented in the statement.

Now we proceed to answer the three questions below:

  1. <em>What is on the x-axis? The y-axis?</em> R/ The x-axis represents the energy (E), in joules. The y-axis represents the amplitude (x), in milimeters.
  2. <em>How would you describe the rate of change of the line?</em> R/ The curve depicts an <em>monotonous decrecent</em> rate of change, that is, the slope converges to zero when the energy tends to infinite.
  3. <em>What does this tell you about the relationship between amplitude and energy?</em> R/ The curve show a strong similarity with a function of the form x = A\cdot \sqrt{E}. Hence, the amplitude is directly proportional to the root square of the energy.

Imagine two lines intersect. How can the properties of linear pairs and vertical angles help to determine the angle measures cre
Vikentia [17]

Answer:When two lines intersect they form two pairs of opposite angles, A + C and B + D. Another word for opposite angles are vertical angles. Vertical angles are always congruent, which means that they are equal. Adjacent angles are angles that come out of the same vertex.

Suppose that, in some distant part of the universe, there is a star with four orbiting planets . One planet makes a trip around
WINSTONCH [101]

Answer: 90 Earth years.

Step-by-step explanation:

Analizing the information provided in the exercise, you need to find the Least Common Multiple (LCM) of the given numbers.

You can follow these steps:

1. You must descompose 6, 9, 15 and 18 into their prime factors:

6=2*3\\\\9=3*3=3^2\\\\15=3*5\\\\18=2*3*3=2*3^2

2. Finally, you need to choose the commons and non commons with their greatest exponents and multiply them. Then you get:

L.C.M=2*3^2*5=2*9*5\\\\L.C.M=90

Therefore, it will take 90 Earth years for them to all line up.
