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
If I’m correct it should be 7 because range is least greatest subtracted from most greatest and the problem is asking from the green box so 67-60=7

<span>The reciprocal of a fraction is simply the reverse
position of the original fraction, its numerator and denominator. It is
represented by the formula of 1/number (fraction). To get the reciprocal of the
number, divide one by the fractional number. You are given the number 6/5. So you
have a numerator of 6 and a denominator of five. Simply swap them and you get
the new numerator as 5 and the new denominator as 6. Or you can just divide
1/(6/5) then you will get 5/6. The answer is letter D.</span>
