For finding inverse function , we do following steps
step-1:
Set f(x)=y
step-2:
Switch x and y
step-3:
now, we can solve for y
Multiply both sides by 9y-2
Add both sides by 2x
now, we can divide both sides by 9x
so, we get inverse function as
................Answer
A particular country has 60 total states. if the areas of all 60 states are added and the sum is divided by 60, the result is 212 comma 469 square kilometers. determine whether this result is a statistic or a parameter.
Answer: Before solving the given question, let us understand what the parameter and statistic is:
Parameter: Parameter is a number that summarizes data for an entire population. Like Population mean Population standard deviation
Statistic: Statistic is a number that summarizes data for a sample. Like sample mean sample standard deviation
.
From the given information, we can clearly see that given characteristic describes the population.
Therefore, the option d is correct
d. the result is a parameter because it describes some characteristic of a population. is correct.
