10 8 4 5 8 6 12 1 Write these data in an increasing order: 1 4 5 6 8 8 10 12 The range of these data is the difference of the larger value and the smaller value: 12 - 1 = 11 Thus, the range is 11.
what is the mode of the following data 18, 17, 12, 14, 8, 21, 10, 11, 19, 20, 10, 5, 17, 12, 10, 20
7*100 = 700 14*10 = 140 11*1 = 11 Sum = 851
First, to find median put numbers in order so: 5, 5, 6, 7, 8, 9, 10, ( 10, 12 ,) 14, 15, 17, 18, 18, 18, 20 10 + 12= 22 divided by 2= 11, the median is 11
11 plus 5-10 plus 20-9 plus 14-10 is equal to 21
10
Range = Maximum - Minimum = 13 - 2 = 11
Mean = 19.8 -----------[(48 + 11 + 15+14+11) / 5]Median = 14 (middle value of the list)Mode = 11 (most frrequent number)Range = 37 (48 - 11, highest - lowest number)
-1
7/10 = 14/20 14/20 + 11/20 = 25/20 = 5/4
10 7 11 12 9 13 14 11 15 16 13 17 18 15 19 20...
Mean: 11.6 Median: 12 Mode: 10, 12, 15, 16, 5 Range: 11
The prime numbers in the range 1-14 are 2, 3, 5, 7, 11 and 13.
Let write the data in an increasing order: p q r s t.Since the median is 14, then r = 14, and we have: p q 14 s t.Since the mode is 11, then p = q = 11.Since the range is 9, then t - p = 9, t - 11 = 9, and t = 20.So, we have: 11 11 14 s 20.Since the mean is 25, we have:(11 + 11 + 14 + s + 20)/5 = 25(56 + s)/5 = 25 multiply by 5 to both sides56 + s = 125 subtract 56 to both sidess = 69So the data set is: 11 11 14 69 20
Range = Max(set) - Min(set) = 13 - 2 = 11
10 8 4 5 8 6 12 1 Write these data in an increasing order: 1 4 5 6 8 8 10 12 The range of these data is the difference of the larger value and the smaller value: 12 - 1 = 11 Thus, the range is 11.
