Use the Venn diagram. Circle A is labeled multiples of 4. Circle B is labeled numbers with ones digit 0. Circle C is labeled numbers greater than 40. The diagram shows A only: 8, 12; B only: 10, 30; C only: none; A and B only: 20, 40; A and C only: 44, 48; B and C only: 50, 70; all three: 60, 80; outside all circles: 7, 9. Which conclusion is NOT supported by the diagram?
