A convenience sample differs from a voluntary sample in thata convenience sample is structured based on accessibility to the researcher, and a voluntary sample is based on participant interest.
convenience samples survey each participant once, and voluntary samples survey each participant numerous times.
convenience sampling is a method of random sampling, and a voluntary sample is not.
convenience sampling is not a probability-based method, and voluntary sampling is.

Answers

Answer:  A convenience sample is structured based on accessibility to the researcher, and a voluntary sample is based on participant interest.


Step-by-step explanation:

For the conventional sample the researcher chooses a sample that is readily available in some non-random way. Thus, it is structured based on accessibility to the researcher.

But for the voluntary sample the researcher puts out a request for participants of a population to join the sample, and participants decide whether or not to be in the sample. Thus, it is based on participant interest.

The best answer to the incomplete statement above would be the first choice. A convenience sample differs from a voluntary sample because a convenience sample is based on how accessible or easily obtained participants are to the researcher, while a voluntary sample is based on the participants' interest of participating.

A triangle has an area of 10 m². The height of the triangle is 5 m.What is the base length of the triangle?

2 m

4 m

5 m

15 m

Answers

area=1/2 times bas time height
given that area=10
height=5
find base

10=1/2 times base times 5
times 2 both siddes
20=base times 5
divide oth sides by 5
4=base

the base is 4m

Alex and Jackson are brothers who are selling mums for a football fundraiser. Together they have sold 37 mums. If Alex has sold 19 more mums than Jackson, how many mums has Jackson sold? Use X to represent the number of mums alex sold and y to represent the number of mums Jackson sold.

Answers

Jackson has sold 18, that’s the only possibility.

x = mums sold by Alex

y = mums sold by Jackson

\boxed{\begin{array}{llll} \stackrel{ \textit{together they've sold 37} }{x + y = 37} \n\n\n \stackrel{ \textit{Alex has sold}}{x} = \stackrel{ Jackson }{y} + 19 \end{array}}\hspace{5em} \begin{array}{llll} \stackrel{\textit{substituting on the 1st equation}}{(y+19)~~ + ~~y~~ = ~~37}\n\n 2y+19=37\n\n 2y=18\n\n y=\cfrac{18}{2}\n\n y=9 \end{array}

Let the function f(x) have the form f(x) = Acos(x + C). To produce a graph that matches the one shown below, what must the value of A be?

Answers

A general cosine function has the form:

f(x) = A*cos(c + x)

We want to find the value of A that matches the one in the image, and we will find that A = 3

Ok, a general cosine function is:

f(x) = A*cos(c + x)

Where A is the amplitude.

To find the amplitude of a cosine function, we just need to find half of the difference between the maximum and minimum value of the function:

By looking at the given graph, we can see that the maximum is y = 3, and the minimum is y = -3

Then the amplitude is:

A = (3 - (-3))/2 = 6/2 = 3

The correct option is B.
