8.3,4.5,6.2,9.6,4.3,11.2,5.9,9.7,10.5
Mean:
To find mean you do the same as you would to find an average. Add up all of the numbers and divide by how many numbers are there. So,
8.3 + 4.5 + 6.2 + 9.6 + 4.3 + 11.2 + 5.9 + 9.7 + 10.5 = 70.2
Then divide by 9 since you have 9 numbers.
70.2 / 9 = 7.8
Median:
To find median you set up the data from least to greatest and cross out one number from each side until you are left with one number as the middle number.
4.3, 4.5, 5.9, 6.2, 8.3, 9.6, 9.7, 10.5, 11.2
4.5, 5.9, 6.2, 8.3, 9.6, 9.7, 10.5
5.9, 6.2, 8.3, 9.6, 9.7
6.2, 8.3, 9.6
= 8.3
Mode:
Mode is the most, meaning the number that appears the most in your set of data. In this case there is no mode because in your set there is no number that occurs more than once.
Hope this helps!
The and answer is going to be 3 because when you multiply 5 and 3 you get 15
I think as in whole numbers in numerator it should be in improper fraction since 4.5= 4wholes and 5/10 it's 9/2?
and 2.5 in mixed fraction is 2 wholes 5/10 in improper is 5/2
unless you say mixed fraction is okay to leave if for the answer than it's respectively 4wholes 1/2 and 2wholes 1/2?
I'm not sure but I learnt this in my school and it goes like this
