What is the difference between a frequency polygon and an ogive? choose the correct answer below.

The difference between the two is that frequency polygon is a graph that presents the information by using lines that connect points plotted for the frequencies at the midpoints of the classes. The frequencies are signified by the heights of the points while the the ogive is a graph that signifies the cumulative frequencies for the classes in a frequency distribution.

An  atom  (ours, not carroll's) consists of a positively charged  nucleus, surrounded by one or more negatively charged particles called  electrons. the positive charges equal the negative charges, so the atom has no overall charge; it is electrically neutral. most of an atom's mass is in its nucleus; the mass of an electron is only 1/1836 the mass of the lightest nucleus, that of hydrogen. although the nucleus is heavy, it is quite small compared with the overall size of an atom. the radius of a typical atom is around 0.1 to 0.25 nanometres (nm), whereas the radius of a nucleus is about 10-6  nm.  *  if an atom were enlarged to the size of the earth, its nucleus would be only 200 feet in diameter and could easily rest inside a small football stadium.read more on -
