37% of 84= 37% * 84= 0.37 * 84= 31.08
76 multiplied by 84 is 6,384.
76/84 = 19/21
Mean = sum/count = 302/4 = 75.5
84-36 = 48
The greatest common factor of 76 and 84 is 4.
84% of 36 is 30.24
84 + 36 = 120.
Mean = "average" = (sum of samples) / (number of samples)Mean = (1/9) x (98 + 98 + 98 + 45 + 84 + 84 + 52 + 45 + 37) = 641/9 = 71.222 (rounded, repeating)
For median the list needs to be sorted into increasing order, but doing so also helps with the range and mode, so I'll do that first: {89, 76, 85, 76, 77, 84} → {76, 76, 77, 84, 85, 89} Mean: add them up and divide the sum by how many numbers there are: mean = (89 + 76 + 85 + 76 + 77 + 84) / 6 = 81 1/6 ≈ 81.167 Median: middle number when listed in order; if there are an even number of data items, then the median is the mean average of the middle two: There are 6 data items so median is mean average of middle two: median = (77 + 84) / 2 = 80 ½ = 80.5 Mode: the most frequent, it the number which occurs the most often. There can be more than one mode: mode = 76 as there are two of them and only 1 of all the other numbers. Range: the difference between the greatest and least numbers: range = 89 - 76 = 13
The mean (average) of these numbers is 70.53 to two decimal places. (The final digit is a repeating 3)
