Question1. Find the midpoint of BD\overline{B D} where B is at (5,6)(-5,-6) and D is at (9,11)(9,11).
2. If M is the midpoint of XY\overline{X Y} with X(1,2)X(1,-2) and M(7,4)M(7,4), find Y's coordinates.
3. Calculate the length of RS\overline{R S} for R(8,2)R(8,2) and S(3,7)S(3,7), rounding to the nearest whole number.
4. Find the weighted average of 6 (weight 4) and 12 (weight 2).

Studdy Solution
Calculate the weighted average.
Weightedaverage=24+246=8Weighted\, average = \frac{24 +24}{6} =8The weighted average of the coordinates is8.
