The range is 36 because 98-62=36.
Hope this helps :)
To find the mean, add the numbers (84 + 85 + 88 + 89 + 82 + 78 + 82) to get 508, then divide by 7, resulting in a mean of approximately 72.57. The median is the middle value when the numbers are arranged in order (78, 82, 82, 84, 85, 88, 89), which is 84. The mode is the number that appears most frequently, which is 82. The range is the difference between the highest (89) and lowest (78) values, giving a range of 11.
To find the mean of the numbers 80, 92, 91, 75, 89, 84, 0, 85, and 78, first add them together: 80 + 92 + 91 + 75 + 89 + 84 + 0 + 85 + 78 = 600. Then, divide the sum by the number of values, which is 9. The mean is 600 ÷ 9 = 66.67.
89% of 62 = 55.18 89% of 62 = 89% * 62 = 89%/100% * 62 = 0.89 * 62 = 55.18
2x + 89 = 78 Therefore, 2x = 78 - 89 x = -11/2 x = -5.5
If I understood you correctly you meant (78*57) - 89? The answer will be 4,357.
Put them in order, least to greatest. 62, 78, 84, 89, 94, 94, 96, 98 The range is the smallest subtracted from the largest. 98 - 62 = 36 The range is 36. The median is the average of the middle two. 89 + 94 = 183 divided by 2 = 91.5 The median is 91.5
Range = 89 - 78 = 11
