Answer:
A normal distribution has a mean of 50 and a standard deviation of 10. What is
the probability of selecting a number between 20 and 60?
Isolate the term that has v :
5 v/9 =z-w
Multiply both sides by 9:
5v =(z-w)•9
Divide both sides by 5:
v= (z-w)•9/5
Answer:
D: 14 = 0.89 x n; 15.7
Step-by-step explanation:
To get 89% of a number you have to multiply that number by 0.89
Use long division to divide 13/15.
This will give you 0.8666... (repeating)
Multiply by 100 to get your percent.
