The statistical mean can also be used to interpret statistical data. Some important properties make statistical mean very useful for measuring central tendency. Since Xi - X is the distance from a given number to the average. The numbers to the left of the mean are balanced by the numbers to the right of the mean.
In review, vertical angles are angles formed by the intersection of two lines while alternate interior angles, alternate exterior angles, corresponding angles and consecutive interior angles are formed by the intersection of two lines and a transversal.
Both pairs of vertical angles (four angles altogether) always sum to a full angle (360Â°). Adjacent angles. In the figure above, an angle from each pair of vertical angles are adjacent angles and are supplementary (add to 180Â°). mâ JQL + mâ LQK = 180Â°. In the figure above, adjust the lines and convince yourself of this fact.
