Answer

  1. 98. 4,830,200

  2. 99. 46,100

  3. 100. 4.13 x 10^4, 5.82 x 10^6, 4.63 x 10^7, 4.7 x 10^7

  4. 101. 3.3 x 10^3, 3.30 x 10^5, 3.3 x 10^9, 3.303 x 10^9, 3.03 x 10^10

  5. 102. The sum of the numbers is 34 + 45 + 32 + 38 + 47 + x = 196 + x. The mean is 37, so (196 + x) / 6 = 37. Solving for x gives x = 26.

  6. 103. Mean: (6 + 5 + 5 + 5 + 8 + 5 + 10 + 4) / 8 = 6. Mode: 5. Median: (5 + 5) / 2 = 5. Range: 10 - 4 = 6.

  7. 104. Stem-and-leaf plot:
    2 | 0 8
    3 | 5 5 6 9 9
    4 | 3 7
    5 | 1 1 2 3 4 4
