77 - (7*8) - 12 = 9
77 - 56 - 12 = 9
LCM(9, 12, 8, 7) = 504
8/9 minus 7/12 is 11/36
8 + 7 - 9 + 6 - 3 = 9 8 + 7 = 15 15 - 9 = 6 6+6 = 12 12 - 3 = 9
The ratio of 5 and 7 8 and 9 12 and 18 85 and 170 is 5:7/8:9/12:18/85:170.
(3/8) / (7/12) = 3/8 * 12/7 = (3*12)/(8*7) = (3*3)/(2/7) = 9/14
Average = (12 + 8 + 7)/3 = 27/3 = 9
In the dataset {8, 0, 7, 7, 9, 12, 3, 7, 4, 6, 7, 8, 9, 6, 4} the 8 appears twice. → The frequency of the 8 is 2.
For 6 7 7 12 12 11 9 9 8 4 6 13 14: σ=3.0947
The expression is: 6/9 + 7/12 Note that 6/9 is evaluated to 2/3. Then we have: 2/3 + 7/12 Since the LCD is 12, multiply the top and bottom by 4 for 2/3 to get: 2/3 * 4/4 + 7/12 = 8/12 + 7/12 Finally... 8/12 + 7/12 = (8 + 7)/12 = 15 / 12 = 1 3/12 = 1 ¼
The Least Common Multiple (LCM) for 7 8 9 12 18 is 504.
It is 4 + 9 + 8 + 5 + 12 + 6 + 7 units.
median(6,9,7,12,12,4,9,6) = 7
