Let your raw score be x and M the mean and S the standard deviation. The Z score for your specific x is Z=(x-M)/S So say your score is 80 (out of 100) and the mean is 70 and the standard deviation is 10. Then the z score for your 80 is: (80-70)/10=1 If on the other hand you got a 60, then the z score would be -1.

Let's denote Zoron's current age as ( Z ) and his sister's age as ( S ). According to the problem, we have two equations: ( Z = S + 10 ) and ( Z + 3 = 2(S + 3) ). Substituting the first equation into the second gives ( (S + 10) + 3 = 2(S + 3) ). Solving this, we find ( S = 7 ) and ( Z = 17 ); thus, Zoron is currently 17 years old, and his sister is 7 years old.
