-9,-11,-8,-12,-10
15
8, 9, 11 and 12
8 and 9/10 = 89/10
9;9;9 Mean = sum of scores / number of scores = 9+9+9 / 3 = 27 / 3 = 9 another example is 7, 9, 11 8, 9, 10 etc even: 7, 8, 12
If you mean: -9-10+8 then their sum is -11
MEAN = ( 8+10 )/2 = 18/2 =9
8.
If you mean: 8 9 10 11 and 12 then the average mean is 10
8mean = (9+3+8+10+12+6)/6= 48/6= 8
If you mean: 7/10, 7/9 and 7/8 then it is 7/8, 7/9 and 7/10 from greatest to least
The mean is 9.6. The median is 8.5. The mode is 8. The range is 14.Rewrite the values from least to greatest:6, 7, 8, 8, 8, 9, 9, 10, 11, 20Mean is the average:(6 + 7 + 8 + 8 + 8 + 9 + 9 + 10 + 11 + 20)/10 = 96/10 = 9/6Median is the middle value:the mean of5th and 6thnumber= (8 + 9)/2 = 17/2 = 8.5Mode is thenumber that is repeated often:8 is repeated thrice so 8 is the mode.Range is the difference of the greatest value and the least value = 20 - 6 = 14
Mean: 9 Median: 8.5 Mode: 14, 6, 8, 10, 9, 5, 7, 13
The mean of these, or any group of ten numbers, is 1/10th of their sum.
median = 8 mean = 7 mean < median.
5, 6, 9, 10, & 10
8, 8, 8, 10, 14, 15 The mean is 10.5 The median is 9. The mode is 8. The range is 7.
