Combine all the numbers, then divide it between the amount of numbers you have.
1+1+9+16+5=32
32/5=6.4
So the average is 6.4.
9 1/16. (1 times 5 is 5, and 13/16 times 5 is 65/16 which is 4 1/16; the 4 adds to the 5 to give 9, and then the 1/16 makes it 9 1/16.)
the average of 7,9,11,12,16 is = (7+9+11+12+16)/5 =11
It's 9 And to do it youself 49 1 9 4 362 5 16 from this do this.. 1 4 5 9 16 49 362 then take one off each side untill one is left 4 5 9 16 49 5 9 16 9
four 1 + 2 + 4 + 9 = 16 four numbers so divide 16 by 4 16/4 = 4 average
The factors of 9 are: 1, 3, 9 The factors of 16 are: 1, 2, 4, 8, 16 The factors of 25 are: 1, 5, 25
(-9)-(36/5) -9-36/5 -16 1/5
9+9+9+9=36-5-5-5-5=16+3+3+3-3=22+1-1-1/1=21

3 1/3 - 1 5/9 = 10/3 - 14/9 = 30/9 - 14/9 = 16/9 = 1 7/9.
9:30am to 1:35pm is 4 hours and 5 minutes. 9:30am to 1:35am is 16 hours and 5 minutes. 9:30pm to 1:35pm is 16 hours and 5 minutes. 9:30pm to 1:35am is 4 hours and 5 minutes.
2.738612788 First, find the mean (average) of all the numbers: 1+2+3+4+5+6+7+8+9 = 45 45 / 9 = 5 Mean is 5 Now take every number and calculate how far it is away from the mean, then square that number 1-5 = -4 ^2 = 16 2-5 = -3 ^2 = 9 3-5 = -2 ^2 = 4 4-5 = -1 ^2 = 1 5-5 = 0 ^2 = 0 6-5 = 1 ^2 = 1 7-5 = 2 ^2 = 4 8-5 = 3 ^2 = 9 9-5 = 4 ^2 = 16 Next, add all the results: 16+9+4+1+0+1+4+9+16 = 60 Then divide by the sample size minus 1 (n-1): 60 / 8 = 7.5 Finally, find the square root of that number: 7.5^ 0.5 = 2.738612788 Answer: 2.738612788
