9
=12*(9+5)/7 = 12*14/7 = 12*2 = 24
Average = (12 + 8 + 7)/3 = 27/3 = 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.
Sample size: 12 Sorted sample: 3, 5, 6, 6, 7, 7, 8, 9, 9, 9, 10, 10 Middle numbers: 7, 8 Average of middle numbers, known as median: 7.5
the average of 7,9,11,12,16 is = (7+9+11+12+16)/5 =11
9
The average is 10... 11+11+9+7+12=50... 50/5=10
The mean of those data points is 9.
A Possible Answer could be: 70 9 12 12 10 5 1
=12*(9+5)/7 = 12*14/7 = 12*2 = 24
Average = (12 + 8 + 7)/3 = 27/3 = 9
To find the average of 5, 7, and 9, you add the numbers together and then divide by the total number of values. In this case, the sum of 5, 7, and 9 is 21. Since there are three numbers, you divide 21 by 3 to get the average, which is 7.
The ratio of 5 and 7 8 and 9 12 and 18 85 and 170 is 5:7/8:9/12:18/85:170.
7
The "N"th term is -7. You can deduce this from: 19 - 7 = 12 - 7 = 5 - 7 = -2 - 7 = -9
it is 7 because 9+3=12-5=7
