Arrange in ascending order:

7 9 10 12 13 13  14 16

The median = the mean of the middle 2 values

= (12 + 13) / 2 = 12.5 hours.

The mean = (7 +9 +10 +12+ 13+ 13+  14+ 16) / 8

Answer:

= \frac{-2(x-6)}{(x+4)(x-4)}

Step-by-step explanation:

\frac{x}{x^2-16} -\frac{3}{x-4}

According to difference of two square;

x² - 16 = x²-4² = (x+4)(x-4)

Substitute;

\frac{x}{(x+4)(x-4)} - \frac{3}{x - 4}\\

Find the LCM
