Solve ProportionsEXAMPLE = 10 ax 1.5=1 x 30 1.5a/1.5 = 30/1.5a=20 Simplify. Divide both sides by 1.5. Solve for x. 1.) x/16 = 45/40 — 2.) x/5 = ¼ —3.) 2.5/10 = x/50 — 4.) x/6 = 2/9 —Find the Range EXAMPLE Order the data from least to greatest 19, 19, 21, 21, 26, 26, 29, 29, 30, 30, 32, 32range = 32-19 = 13 The range is the difference between the greatest and the least data items. Find the range of the data. 5. 52, 48, 57, 47, 49, 60, 59,51 _ 6. 5,9,13,6,4,5,8,12, 12,6 7. 97, 106, 99, 97, 115,95, 108, 100 8. 27, 13, 35, 19, 71, 12, 66, 47, 39_ Find the Mean EXAMPLE 21, 15, 26, 19, 25, 14 mean - 21+ 15 + 26 + 19 + 25 + 14 The mean is the sum of the data items divided by the number of items. 120 = 20 Find the mean of each set of data. 9. 3,5,7,3,6, 4, 8, 6, 9,5 10. 8.1, 9.4, 11.3, 6.7,6.2, 7.5 |
