Answer:
369 students have taken a course in either calculus or discrete mathematics
Step-by-step explanation:
I am going to build the Venn's diagram of these values.
I am going to say that:
A is the number of students who have taken a course in calculus.
B is the number of students who have taken a course in discrete mathematics.
We have that:
In which a is the number of students who have taken a course in calculus but not in discrete mathematics and is the number of students who have taken a course in both calculus and discrete mathematics.
By the same logic, we have that:
188 who have taken courses in both calculus and discrete mathematics.
This means that
212 who have taken a course in discrete mathematics
This means that
345 students at a college who have taken a course in calculus
This means that
How many students have taken a course in either calculus or discrete mathematics
369 students have taken a course in either calculus or discrete mathematics
Let's analyse the function
The amplitude is A, so we want A=1.5
Now, we start at x=0, and we have
After one second, i.e. x=1, we want this sine function to make 330 cycles, i.e. the argument must be
So, we have
so, the function is
