The standard deviation of a particular sample is equal to the standard deviation divided by the square root of the sample size. That is,

The mean of a particular sample is equal to the mean of the set the sample was taken from. That is,

The little red dashes on the segments means they are congruent. EM = MG
Let's plug the expressions from the picture into our equation above.
7x = 8x - 6
Subtract 8x from both sides.
-x = -6
Divide both sides by -1
x = 6
EM = 7x = 7(6) = 42
35% of 60 = (35/100)*60 = 0.35 * 60 = 21
30% of 80 = (30/100)*80 = 0.30 * 80 = 24
24 is greater than 21.
30% of 80 is greater.
