The common multiple for 1/2 1/4 1/6 1/3 and 1/5 would be 60:
2 x 30 = 60
3 x 20 = 60
4 x 15 = 60
5 x 12 = 60
6 x 10 = 60
Answer:
12.41 or 12 5/12
Step-by-step explanation:
add 5.66+6.75=12.41
or 5 2/3 +6 3/4, get common denominator which is 12, then divide to get 5 8/12 +6 9/12= 11 17/12 or 12 5/12

Answer:
The standard error of the mean = 2
Step-by-step explanation:
Given that:
The standard deviation σ = 14
The sample size n = 49
The sample mean
= 56
The formula for calculating the standard error can be expressed as:



S.E = 2
Therefore, the standard error of the mean = 2
