Answer:
0.868 = 86.8% probability that the student passes.
Step-by-step explanation:
Probability of the student passing:
94% of 91%(when the student studies for the test).
14% of 100 - 91 = 9%(when the student does not study for the test). So

0.868 = 86.8% probability that the student passes.
Well the square root of 5 is 2.3607 and if you add four to that you get 6.3607. is this what you are asking?
Given:
The function is:

The graphs of functions
and
.
To find:
The function
.
Solution:
We have,

The function
is vertically compresses to get the graph of the function
. So, the function
is:

...(i)
From the given graph it is clear that the graph of the function
passes through the point (3,3). So, putting
and
in the above function, we get




Putting
in (i), we get
Therefore, the correct option is D.
It’s equal to 1/2 in simplest form
