Answer:
Step-by-step explanation:
Express the fraction as number of houses over number of businesses, that is
ratio =
Divide numerator and denominator by 5 for simplest form
ratio =
Let
x-----------> the probability that someone buys a book that is paperback
y----------> the probability that someone buys a book that is a fiction
P-----> the probability that someone buys a book that is paperback and fiction
we know that
so
substitute the values
therefore
<u>the answer is the option A</u>
The inverse of the function is y =
In order to find this, you must start by switching the y and x values. Once you do this, you can solve for the new y value and that will be in inverse. The work is done for you below.
y = 2x^2 + 2 ---> switch x and y
x = 2y^2 + 2 ---> subtract 2 from both sides
x - 2 = 2y^2 ---> divide both sides by 2
= y^2 ---> take the square root of both sides.
= y
