15 - 7 = 8
The range is 11.
Mean = 13.44.. recurring Median = 15 Mode = 9 and 15 Range = 17
15
8
First put them in ascending order. 1, 5, 7, 9, 9, 12, 14, 15, 18 Mean is 10 Median is 9 Mode is 9 Range is 17
The range is 7.
The LCM of 15, 9, 7 is 315.
Range is the positive difference between the smallest and largest number.Step 1: Put all the numbers in order from smallest to largest.6, 6, 7, 8, 9, 12, 15Smallest #: 6Largest #: 1515- 6------9Your range is 9.
8, 8, 8, 10, 14, 15 The mean is 10.5 The median is 9. The mode is 8. The range is 7.
It is: (15-7)*(12-9) = 24
9 15 15 15 16 (five data) Range = 16 - 9 = 7 Mean = (9 + 15 + 15 + 15 + 16)/5 = 70/5 = 14 So we have: (9 - 14)2 = (-5)2 = 25 (the square of the difference of data value and the mean value) (15 - 14)2 = 12 = 1, 3(1) = 3 (16 - 14)2 = 22 = 4, the sum is 32 The standard deviation = √(32/5) ≈ 2.5
5 + 15 - (-3)*(-9) = 5 + 15 - 27 = -7. Simple!
