Answer:

The way the sample was chosen may overrepresent or underrepresent students taking certain language classes.

Step-by-step explanation:

<u>Answer options:</u>

The sample size is not large enough to represent the population.

  • No. Sample size is quite small per language.

The sample was not chosen at random.

  • No. There is no evidence if samples are not random.

The way the sample was chosen may overrepresent or underrepresent students taking certain language classes.

  • Yes. Some of the classes my have large, some may have small population. Therefore taking 10 samples from each language is not right proportion and proper representation.

The way the sample was chosen does not sample students from each different language class.

  • No. Each language class is considered.

4. Solve the following system of equations for x.
Ber [7]

We are given the system of equations -:

\large{ \begin{cases} 2x + 3y =  - 14 \\ y = 6x + 22 \end{cases}}

Since the second equation is y-isolated equation. It can be substituted as y = 6x+22 in the first equation.

\large{2x + 3(6x + 22) =  - 14}

Expand 3 in the expression so we can combine like terms and isolate x-variable.

\large{2x + 18x + 66 =  - 14}

Then combine like terms.

\large{20x + 66 =  - 14}

Get rid of 66 from the left side by subtracting both sides by itself.

\large{20x + 66 - 66 =  - 14 - 66} \\  \large{20x =  - 80}

To finally isolate the variable, divide both sides by 20 so we can leave x only on the left side.

\large{ \frac{20x}{20}  =  \frac{ - 80}{20} }

Simplify to the simplest form.

\large{x =  - 4}

Normally, we have to find the y-value too but since we only find x-value. The answer is x = -4.

Answer

  • x = -4

I hope this helps! If you have any questions or doubts regarding my answer, explanation or system of equations, feel free to ask!
