Answer:
The margin of error is 0.1215
Step-by-step explanation:
A confidence interval has two bounds, a lower bound and an upper bound. The margin of error is the difference between these two bounds, divided by 2.
In this problem, we have that:
Lower bound: 0.5627
Upper bound: 0.8057
What is the margin of error?
(0.8057 - 0.5627)/2 = 0.1215
The margin of error is 0.1215
1. 540
2. 480
3.525
you do the rest

Hi!
We can see here that this is a composition question.
And since the composition of g of f of x is x, we can conclude that g(x) is the inverse of f(x) (if you're confused, search up the definition of an inverse function).
To find an inverse function, we can take the f(x) function and change the positions of the x and y variables.







Which is answer choice A, to check your work, you can solve the composition of g(f(x)), which will get you x.

Actually the formula for the area of a triangle is A = 1/2bh.
First step: multiply both sides by 2, to get rid of the 1/2.
2A = bh
Now divide both sides by b.
2A/b = h or h = 2A/b
