eight the 5 numbers add up 6 + 6 + 9 + 9 + 10 = 12 + 18 + 10 = 40 then divide by that 5 so 40 / 5 = 8
You mean "What percentage is 90 million of 5 billion?" If so, [(90 x 10^6) x 100] / (5 x 10^9) = (9 x 10^9) / (5 x 10^9) = 9/5 = 1.8%
The mean of those data points is 9.
-9,-11,-8,-12,-10
9 - 10 - 5 - 12 = -18

eight the 5 numbers add up 6 + 6 + 9 + 9 + 10 = 12 + 18 + 10 = 40 then divide by that 5 so 40 / 5 = 8
12 + 7 + 13 + 10 + 3 = 45/5 = 9
5+7+9+12+12 = 45 and 45/5 = 9 which is the mean average
9/10 ÷ 5/12 = 54/25 or 24/25
Mean = (9 + 10 + 2 + 5 + 5)/5 = 31/5 = 6.2
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
- (3/4) - (-5/6) = - (9/12) - (-10/12) = - 9/12 + 10/12 = 1/12
4/5 = 0.8 5/7 ≈ 0.71 8/9 ≈ 0.89 10/12 ≈ 0.83 11/12 ≈ 0.92 Thus, the greater is 11/12. 11/12, 8/9, 10/12, 4/5, and 5/7.
If you mean: 8 9 10 11 and 12 then the average mean is 10
mean: 9 ordered sample: 7, 8, 8, 10, 12 median: 8 mode: 8 range: 12 - 7 = 5
