(79, 81, 82, 91, 93, 95, 95) The mean is 88 The mode is 95 The median is 91
The mean is 83.
97.8
70, 72, 74, 75, 76, 77, 78, 80, 81, 82, 84, 85, 86, 87, 88, 90, 91, 92, 93, 94, 95, 96, 98, 99, 100
(80 + 85 + 100 + 95 + 95 + 95) = 550/6 = 91.6 recurring (that is, 91.6666...)
The mean is the average (all numbers added and divided by the number of values) The median is the middle number when arranged numerically low-to-high The mode is the most frequently appearing number. 92 86 90 74 95 100 90 50 arrange them for more readability: 50, 74, 86, 90, 90, 92, 95, 100 For the mean: 50+74+86+90+90+92+95+100 = 677 There are 8 numbers, so 677/8, 677/8 = 84.625 or 84 5/8 For the median: Since there are an even number of values, you add the two center values, and divide by two. 90 + 90 = 180 180 / 2 = 90 For the mode: The number 90 appears twice, which is the most frequent, so the mode is 90.
Finding 74 per cent of 95 is the same as saying 95 x 0.74. The answer to this sum, 95 x 0.74 = 70.3, or 70 and three tenths.
number of composite numbers between 81 and 100 = 15composite numbers between 81 and 100 = 82, 84, 85, 86, 87, 88, 90, 91, 92, 93, 94, 95, 96, 98, 99
