Yes 678.05 is greater than 67.805 (because obviously 678 is greater than 67 right? ^ - ^)
I don’t know how ybyybbyyb
Mean=total/the number of values =>total=mean*the number of values
the total of the first set of 8 numbers is : total=8*8=64
the total of the second set of 12 numbers is: 12m
the total of the 20 numbers is: 64+12m
the mean of the 20 number is: (64+12m)/20=5
solve for m: 64+12m=100
12m=36
m=3
