Answer: The results do not represent the population because the sample does not represent professors from different areas.
Step-by-step explanation:
Since Traverion wants to find the answer to the question “How much money does the average college professor make?”
He only surveys 50 professors from the university in his hometown.
Although he should survey professors from different areas but he only perform his survey only a specific university in his hometown.
Therefore, the survey is biased as the sample size is too small.
Hence, The results do not represent the population because the sample does not represent professors from different areas.
Your answer would be 1, or 72+25.
What is happening in this case is a negative number is being subtracted from a positive. This means you are taking away a negative. The two negatives cancel each other out, and then it becomes you are adding a positive.
Another way I like to think about this is the two minus symbols combine together to form a plus sign.
Hope this helped!

Answer:
f^-1(x) = (x +4)/3
Step-by-step explanation:
The inverse function is found by swapping x and y, then solving for y.
y = 3x -4 . . . . . function y = f(x)
x = 3y -4 . . . . . inverse relation
x +4 = 3y . . . . add 4
(x +4)/3 = y . . . divide by 3. This is the inverse function
f^-1(x) = (x +4)/3
