Avenn diagram is shown below: in circle a: 2,5 in circle b: 1,7 intersection: 3,4 what are the elements of (a ∩ b) ' ? answer choices below: {1, 3, 4, 7} {2, 3, 4, 5} {3, 4} {1, 2, 5, 7}

(A ∩ B) means "A intersection B". Your problem statement tells you the intersection contains
  {3, 4}

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. if you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.
