Find the value of x
46
54
40
56
We have CE × CD = CA × CB
(x + 6) × 6 = (18 + 12) × 12
x + 6 = 60
x = 54
Using the following data, construct a frequency distribution table: 46, 44, 42, 54, 52, 60, 50, 58, 56, 62, 50, 56, 54, 58 and 48. Now answer the following: (iii) How many numbers are between 40 and 50 ?
