Quizplus · Accepted Answer

The midpoint of a line segment with endpoints $(x_1,y_1,z_1)$ and $(x_2,y_2,z_2)$ is $\left(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2},\frac{z_1+z_2}{2}ight)$. Applying this formula, we get $$\left(\frac{4+7}{2}, \frac{8+10}{2}, \frac{4+7}{2}ight) = (5.5,9,5.5)$$
Therefore, the correct choice is $\boxed{	ext{(E)}}$.
