Z score is a statistical that corresponds to the standarization of the regular score to a normal dsitribution
The formula for Z score is Z = [X - mean ]./ (standar deviation)
Here X = 930.00; mean = 900.00; and standard deviation = 15.00
Then, Z = [930.00 - 900.00] / 15.00 = 30.00 / 15.00 = 2.00
Answer: 2.00

Answer:
i believe the answer is 117$
Step-by-step explanation:7*15=105 8*1.50=12... 12+105=117
1 / 128 = (2/3) / x....1 cup to 128 grams = 2/3 cups to x grams
cross multiply
(1)(x) = (128)(2/3)
x = 256/3
x = 85.3
he went over...
85.3 - 32 = 53.3....he went over by 53.3 (or 53 1/3) grams
