x/240 = 82/100
240 : 100 = 2.4
so 240 is divided with 2,4 giving 100, this will work with 82 too. So, 82 × 2.4 = 196,8
Answer : x = 196,8
prove :
196,8/240 = 82/100 = 41/50

Answer:
The value remain unchanged.
Step-by-step explanation:
By Z score, we mean:
Z = , if we substitute the given values of mean and standard deviation, we obtain the z score value. That is,
Z = = 85/12 = 7.083333.
NB: We assume that mean and standard deviation are in the same units.
