Question 225672: a. Make a conjecture about the formula for midpoint in three dimensions. Hint: 3D coordinates are given as (x, y, z).
b. Use the formula from the previous step to find the midpoint of (3, 1, 0) and (11, -8, 15).
HELP!

Use the formula from the previous step to find the midpoint of (3, 1, 0) and (11, -8, 15).
----------
Find the averages of x, y and z separately.
x: (3+11)/2 = 7
y: (1-8)/2 = -7/2
z: (0+15)/2 = 15/2
Midpoint is (7,-7/2,15/2)
