It can be written as a fraction, so it is rational.
Alternate "multiply last term by 2" and "add 3 to last term"2 x 2 = 4, 4 + 3 = 77 x 2 = 14, 14 + 3 = 17etc
the sum of two whole numbers are 77 .their difference is 48.what are the two numbers
The cumulative frequency curve is shaped like an S. The lower quartile is 1/4 the way up on the cumulative frequency axis. The upper quartile is 3/4 the way up on the cumulative frequency axis The inter-quartile range is the upper quartile minus the lower quartile as plotted on the horizontal axis. Further details can be found in a higher level maths text book.
If: 2+3x = 77 Then: x = 25
71 is the median of those numbers.
70, 72, 74, 75, 76, 77, 78, 80
74 74 75 77 80The median is 75.
70, 72, 74, 75, 76, 77, 78, 80
66
The composite numbers between 70 and 80 are 72, 74, 75, 76, 77 and 78.
Median: 80 Mode: 72, 80, 120, 98, 78, 84, 77
65, 66, 68, 69, 70, 72, 74, 75, 76, 77, 78, 80

62, 63, 64, 65, 66, 68, 69, 70, 72, 74, 75, 76, 77 and 78.
62, 63, 64, 65, 66, 68, 69, 70, 72, 74, 75, 76, 77 and 78.
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
