Detailed explanation-1: -Answer: Range =largest value-smallest value=10-2=8. mean=sum of all observations/number of observations=2+4+6+8+10=30/5=6.
Detailed explanation-2: -If a mathematical relationship is given in a table, the independent values, generally listed in the left-hand column, are the domain, and the dependent values, usually found in the right-hand column, make up the range.
Detailed explanation-3: -The range of a relation is the set of the second coordinates from the ordered pairs.
Detailed explanation-4: -The range is the set of all second elements of ordered pairs (y-coordinates). Only the elements “used” by the relation or function constitute the range. Domain: all x-values that are to be used (independent values). Range: all y-values that are used (dependent values).
