Answer:
Sample size should be atleast 55320
Step-by-step explanation:
Given that a group of statistics students decided to conduct a survey at their university to find the average (mean) amount of time students spent studying per week.
population standard deviation
Std error =
Margin of error for 95%
=
Since sample size is number of items it cannot be indecimal.
So we can round off to the next high integer on a safer side.
Answer:
Inverse function are symmetric with respect to line y=x.
It can be written as:
and
Let's rewrite the given function notation by using y term.
f(x) = 6x-1
i.,e y = 6x-1
Let's solve this equation for x;
Add 1 to both sides we get;
y+1 =6x
Divide both sides by 6 we get;
Now, switch the "x" and "y" we have;
In the function notation:
