This is Simple
Too work out the mean you add the numbers together ( 3+2+9+7=21)
Then simply divde that number by the amount of numbers you have added together ( 21dividedby4=5)
Your awsner is 5
If you mean: 2 times (8+7)-6 then divided by 2 times (9-3) then the answer is 2
2+3+7+9+3=24
The average or mean of 3, 5, 7, 9, and 11 is 7.
the awnser will be 7 3+3=6+3=9 9-2=7-0=ANS=7
When there is an even number of data items the median is the mean average of the middle two. → median of {2, 3, 4, 5, 7, 9} = (4 + 5)/2 = 9/2 = 4.5
2
The mean is 4.55... recurring.
If you mean: 2 times (8+7)-6 then divided by 2 times (9-3) then the answer is 2
15.
2+3+7+9+3=24
The mean is 5. The median is 5. There are two modes = 2 and 7. The range is 7.
6.
To find the mean absolute deviation (MAD) of the data set 2, 3, 5, 7, 8, 8, 9, first calculate the mean, which is 6. Then, find the absolute deviations from the mean: |2-6|, |3-6|, |5-6|, |7-6|, |8-6|, |8-6|, |9-6|, resulting in 4, 3, 1, 1, 2, 2, and 3. The average of these absolute deviations is (4 + 3 + 1 + 1 + 2 + 2 + 3) / 7 = 2. Therefore, the MAD is 2.
6.6 repeated
If you're a little cheaty about it, 9 + 7 + (2^3) = 24. But the better answer is 3 * (9 + 7) / 2.
The average or mean of 3, 5, 7, 9, and 11 is 7.
Mean: 5 Median: 5 Mode: 3
