Consider the triangles shown below. which of the following relationship is needed to prove that abd

A. is the answer.

the 2 triangls have AD = AC

and AB as a common side. therefore the triangls are congruent.

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
