10 We think they (people of African ancestry] are ... not included, and were not intended to be included, under
the word "citizens" in the Constitution, and can therefore claim none of the rights and privileges which that
instrument provides for and secures to citizens of the United States.

Which Supreme Court decision is excerpted above?

dred Scott vs. standford

Explanation: trust me

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 % " .
