80,000going up by 10% you just add the 10% on
First one: x <= -1
Second one: x > 4/3
Since you logically OR them together, the answer will be simply the combination of them two:
x <=-1 or x> 4/3
Answer: The conclusion cannot be confirmed unless we have the statistic of the men.
Step-by-step explanation: Only looking at the number of women in both times 8 am and 10 am, will not determine if the men prefer of do no prefer earlier classes. We would need the men's statistics as well for both time slots. There may be more men among the 8 am slot e.g 25 women and 30 men. There is incomplete information to come up with a sound conclusion.
the value of f-1(27) is 9.
In order to find this answer, we first have to find the inverse function (since that is what f-1 means). To do this, we switch the f(x) value and the x. Then we solve for the new f(x). The result is the inverse function. The work for this is below.
f(x) = 3x ----> Switch the f(x) and the x.
x = 3f(x) ---> divide by 3.
f-1(x) = 
.
Now that we have this, we can plug in 27 (the number in parenthesis) and find the result.
f-1(x) =
f-1(27) = 
f-1(27) = 9
