Answer:
66.67%
Step-by-step explanation:
75 /100 = .75
.75n = 45
45/.75 = 60
60 is n
60/90 = .666667
.666667 * 100 = 66.67%
Answer:
The average rate of change is 8.
Step-by-step explanation:
The formula to calculate the average rate of change of a function F(x) is:

In this case, F(x) = 
a=2 and b=4
You have to evaluate x=2 (which is a in the formula) and x=4 (which is b in the formula) in the function.
In order to obtain F(b) and F(a) you have to replace x=4 and x=2 in the given function:
F(b) = 
F(a) = 

The answer is 8.
Answer:
The correct option is A.
Step-by-step explanation:
Consider the complete question is "The table shows the transportation method used by the employees in an office.
Transportation Number of employees
Car 18
Bus 6
Walk 6
what is the probability that the next two employees that join the office staff will take the bus? A.0.04, B.0.12, C.0.33, D.0.36.
Total number of employees = 18 + 6 + 6 = 30
The probability that the employees take the bus = 
The probability that the employees that join the office staff will take the bus is

Therefore, the correct option is A.
A family has 8 girls and 4 boys. A total of 3 children must be chosen to speak on the behalf of the family at a local benefit. What is the probability that no girls and 3 boys will be chosen?
D. 1/55.<span />
Hint to start out the problem:
eg. For f(4), use the first expression, (x-3)^2 because 4 is greater than 1.
