Answer:
-1.58
Step-by-step explanation:
We have that the mean (m) is equal to 89 and the standard deviation (sd) 2.4
They ask us for P (x <85.2)
For this, the first thing is to calculate z, which is given by the following equation:
z = (x - m) / (sd)
We have all these values, replacing we have:
z = (85.2 - 89) / (2.4)
z = -1.58
Answer:
c

Answer:
871
Step-by-step explanation:
737 divided by 11 is 67, so thats how many miles he drives per hour
67 times 13 is 871
1/x^2 / 3/x^3
1/x^2 * x^3/3=x/3
Answer: The slope is 2/3:)
Step-by-step explanation: (2,5) and (8,9)
9-5 =4 /2=2
8-2 =6 /2= 3
