Answer:
<h2>0</h2>
Step-by-step explanation:
METHOD 1.
We know:

Therefore

METHOD 2.


exchange x to y and vice versa:

solve for y:
<em> subtract 12 from both sides</em>
<em>divide both sides by 3</em>

replace x in f(x) with the expression

put x = 0 to 

METHOD 3.


Calculate the value of <em>f</em> ⁻¹(x) for x = 0:

Calculate the value of <em>f(x)</em> for x = -4:

Because base angles are congruent, both angle A and B are congruent. If the two triangles are congruent, then the base angles are the same, meaning 5x=50*. Divide by 10 and you get the answer of x=5. :) Hope this helps!
The correct order to determine if the results are significant are as follows:
1. Randomly separate the employee's individual results into two groups.
2.Calculate the mean of each group.
3. Calculate the difference of the means
4. Run the experiment many times
5. Calculate the probability of a difference of 5.
These steps are used to determine statistical significance by finding difference of means.
