10 is the answer.
You know that there are 4 numbers and you have to add the numbers then divide them by four to get the mean. So all you have to do is reverse the steps, multiply 30 by 4 to get 120, then add 12+50+48 to get 110. Then subtract, 120-110=10. To check if it is correct add 12, 50, 48, and 10 to get 120, then divide by 4 to get 30. And voila, there is the answer. I hope this helped for future problems like this one.
Answer:
All real values of x except x = 5
Step-by-step explanation:
The questions asks for the domain of [f/g](x).
That is f(x) / g(x) = [x^2 - 25] / [X-5].
The domain of that functions are all the real except those where the denominator becomes zero.
You find those points by doing X - 5 = 0 => x = 5.
Then, the domain of [f/g](x) is all real numbers except x = 5.
ln(2e/x)
ln2+ ln e -ln x
ln 2 + 1 - ln x
OPTION D is the correct answer
Answer:
Consider the function f (x) = (x +4) (x + 2).
