Step-by-step explanation:
Formula we use to find the z-score :-
(1)
Given : 
Daniel's z score : z= 1.67
Let x be the raw score for Daniel's exam grade, then substitute the values of 
in (1), we get

Answer:
x=-2 and x=0
Step-by-step explanation:
5(x-2)^2 = 20; divide by 5 both sides
(x-2)^2 = 4; take the square root of both sides
(x-2) = ±2, now set it equal to positive 2 and negative 2
x-2 = 2
x=4
AND
x-2 = -2
x=0
X=30 in the first one and x=-15 in the second one
