Answer:
1/12
Step-by-step explanation:
You are close but 1/27 includes people who did not study but still passed. If you want a singular value you should look at the value for the for only the people who studied even if they passed.
Twice a number is the same as
A number used twice
If that number where represent by x
Then
If x was used twice would look like
What
First we compute the distance between the center and the given point which is exactly the radius
r =

Now that we know the center and the radius, we can write the equation of a circle with given radius and center:

where (h,k) represent the coordinates of the center (3,7).
We substitute and obtain

The function that is a reflection of f(x) over the y-axis is h(x) = 2(0.35)^(-x)
<h3>How to determine the reflection?</h3>
The equation is given as:
f(x) = 2(0.35)^x
The reflection of a function over the y-axis is :
f'(x) = f(-x)
So, we have:
f(-x) = 2(0.35)^(-x)
From the list of options, we have
h(x) = 2(0.35)^(-x)
Hence, the function that is a reflection of f(x) over the y-axis is h(x) = 2(0.35)^(-x)
