Aconvex lens has a diameter of 30 mm and a depth of 5 mm at the center. how far from the vertex is the focus?

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.

d. it is a convex pentagon because it has five sides and none of the sides would extend into the inside of the polygon.
