It would be 9!!!
Hope that helps!!!
Using the Quadratic Function, Such Means x = - b + or - the square root of - 4 a c over 2 a.
After you do it you would get the answer :
Hoped I Helped, Have A Great Day :)
<u>Solution</u><u>:</u>
- Now, square root and square gets cancel out in the LHS. And in the RHS, apply the identity: (a + b)² = a² + 2ab + b².
- Now, transpose 4x and 4 to LHS.
- Now, do the addition and subtraction.
<u>Answer</u><u>:</u>
<u>x </u><u>=</u><u> </u><u>±</u><u> </u><u>3</u>
Hope you could understand.

As you probably know there is a difference between mean and median -- the mean acts as a measure of the average, and on the other hand median measures the middle number. The median in this is 15 and the mean is also 15.
All you need to do is divide 96 by 8 and you get 12 as your answer
