The medians of a triangle intersect at a point called the A) centroid.
B) incenter.
C) midpoint.
D) median.

Centroid

Step-by-step explanation:

A triangle only has three medians, which intersect at the centroid. A triangle also only has three vertices, which follows the three medians.

answer: a and c are correct

step-by-step explanation:

the +5 is the vertical translation

the added negative symbol in front is the reflection over the y-axis

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.
