<span>Answer: Skewed to right with mean 0 and S.D. 1
Explanation: Let's assume the z-scores as a linear transformation.
then z=(x-mean)/S.D. = (x-30)/15
z(mean) = (30-30)/15= 0
z(sigma) = 15/15 = 1
Note: Shape does not change.</span>

Answer:
x = 0
Step-by-step explanation:
6 ( x + 1 ) - 5x = 8 + 2 ( x - 1 )
6x + 6 - 5x = 8 + 2x - 2
-x = 0
x = 0
