Rainfall data — Answer key

Work through each question. Show your reasoning where space is provided.

  1. 1. Three months recorded 9, 66 and 9 mm of rainfall. Find the total and mean monthly rainfall.

    84 mm; 28 mm

    Total = 9 + 66 + 9 = 84 mm. Mean = 84 ÷ 3 = 28 mm.

  2. 2. Three months recorded 42, 84 and 51 mm of rainfall. Find the total and mean monthly rainfall.

    177 mm; 59 mm

    Total = 42 + 84 + 51 = 177 mm. Mean = 177 ÷ 3 = 59 mm.

  3. 3. Three months recorded 21, 21 and 51 mm of rainfall. Find the total and mean monthly rainfall.

    93 mm; 31 mm

    Total = 21 + 21 + 51 = 93 mm. Mean = 93 ÷ 3 = 31 mm.

  4. 4. Three months recorded 30, 18 and 54 mm of rainfall. Find the total and mean monthly rainfall.

    102 mm; 34 mm

    Total = 30 + 18 + 54 = 102 mm. Mean = 102 ÷ 3 = 34 mm.

  5. 5. Three months recorded 81, 27 and 39 mm of rainfall. Find the total and mean monthly rainfall.

    147 mm; 49 mm

    Total = 81 + 27 + 39 = 147 mm. Mean = 147 ÷ 3 = 49 mm.
