Answer:
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:
b=-2
Step-by-step explanation:
-(-b+5)+5b=-19-b
b-5+5b=-19-b
b+b-5+5b=-19-b+b
2b-5+5+5b=-19+5
2b+5b=-14
7b=-14
7b/7=-14/7
b=-2
