On these two number lines what do the shaded dots represent ? 20 points

A shaded dot on a number line indicates that the given number should be included as a possible solution, whereas an open dot indicates that the given number can't be a solution. For example, if you graph x > 7, you place an open dot at 7 because it's not a valid answer (7 is not greater than itself).

h * s * a

h = history teacher

s = science teacher

a =   art teacher.

i see no data table, but just multiply the number of history teachers, science teachers, and art teachers.
