To find the percentage,we need to form a fraction first:
The nominator would be: the students who have not blue eye and were not wearing orange at the same time (50)
The denominator: students with not blue eyes (20)
Hence we can form the fraction: 20/50
To find the percentage, we can multiply the fraction by 100%:
20/50x100%
=2/5 x 100%
= 200/5 %
= 40%
Therefore the answer is 40%.
Hope it helps!
False they will be parrallel and never meet
Here is an example:
Find the MAD of 2,4,6,8 Step 1 : Find the mean of the data : (2+4+6+8) / 4 = 20/5 = 4 Step 2 : Find the distance between each data and mean. Distance between 2 and 5 is 3 Distance between 4 and 5 is 1 Distance between 6 and 5 is 1 Distance between 8 and 5 is 3
Step 3 : Add all the distances : 3+1+1+3 = 8
Step 4 : Divide it by the number of data : 8 / 4 = 2 2 is the average absolute deviation.
