The form of visual representation of data that is best suited when statistician desires to collate trends in European and American consumption of fast food while also desiring to get the big picture of how consumption has changed by tracing a huge period of time is by using a table.

Handwritten notes, computer software, architectural ornamentation, and print media are some of the places where tables appear and depending on the context, their precise conventions and terminology for describing tables vary.

the correct answer is:   "   3.6 % " .

          →   the unemployment rate is:   " 3.6 % " .

explanation:

to calculate the "unemployment rate" :

the "unemployment rate"   =

  [# of people unemployed] /   [working age population]   * 100 %   ;

                =   [9 million] / [250 million]     *   100 % ;

    →     note:   the units of "million" cancel out;

                    since:   " {million} / {million} = 1 " ;

                =   (9 / 250)   * 100 %   ;

                = 0.036 * 100 % ;

                =   3.6 %

answer:   the unemployment rate is:   " 3.6 % " .
