The surveyor selects the twentieth student who enters the building. The student do not enter the building to be surveyed but for other reasons and the researcher take advantage of that and selects them. This is a form of continence sampling.
 The researcher selects every twentieth student and not any other. Therefore, the sampling is systematic in nature.
Finally, students selected to participate in the survey are free to choose if to participate in he survey or not. Therefore, it is voluntary kind of sampling.

Therefore, the applicable sampling methods are convenience, systematic, and voluntary.

Find The Value x ~<br><img src="https://tex.z-dn.net/?f=%20%5Clarge%20%5Csf%20%5Cunderline%20%5Cbold%7B4x%20%2B%2026%20%3D%2016%

The value of x in the algebraic equation is: -5/2.

<h3>How do you Find the Value of a Variable in an Algebraic Equation?</h3>

Given an algebraic equation, to find the unknown value of x, solve by isolating x in the equation.

Given:

4x + 26 = 16

Subtract 26 from both sides

4x = 16 - 26

4x = -10

Divide both sides by 4

x = -10/4

x = -5/2

Therefore, the value of x in the algebraic equation is: -5/2.

Oduvanchick [21]

Answer: The ratio of protein bars to water bottles will be 4:3.

Explanation:

Since we have given that

Number of protein bars = 20

Number of water bottles = 15

We need to calculate the ratio of protein bars to water bottles which is given by

\text{ Number of protein bars}:\text{ Number of water bottles }\\\\=20:15\\\\=4:3

So, the ratio of protein bars to water bottles will be 4:3.
