Answer:
z-score for 900 points = -4

z=(900-1500)/150
z= -600/150
Answer:
63
Step-by-step explanation:
11.25 seems to be the answer they want, despite the lack of important information.
To put a fraction into simplest form, you need to divide both the numerator and the denominator by the GCF of both of these numbers.
35 and 42 have a GCF of 7.
So, if we divide
35/7=5
42/7=6
Therefore, 35/42 in simplest form is 5/6
