Answer:15 seniors served on the student council during their freshman year, 14 seniors served during their sophomore year, 16 seniors served during their junior year, and 3 seniors have never served before.
Step-by-step explanation:
Using inclusion and exclusion principles, we find that 2 seniors served on the student council during each of the four years in high school.
The problem can be solved using the Principle of Inclusion and Exclusion (PIE), a common technique in combinatorial mathematics. First, we add the number of seniors serving in their freshman, sophomore, and junior years: 3 (never served) + 10 (junior) + 9 (sophomore) + 11 (freshman) giving us 33.
Then, we subtract the number of seniors who served during both sophomore and junior years, freshman and junior years, and freshman and sophomore years: 33 - 5 (sophomore and junior) - 6 (freshman and junior) - 4 (freshman and sophomore). This results in 18.
However, from the initial condition we know that there are 20 seniors in total. Therefore, the two 'extra' seniors must have served all four years in high school. Thus we find that 2 seniors served on the student council during each of the four years in high school.

Answer:
One solution to this question could be that g(xl=x^2 and f(x)=sqrt{x+1}
Step-by-step explanation:

The value of y is 67 degrees when line segment BD is parallel to XY.
A coordinate geometry is a branch of geometry where the position of the points on the plane is defined with the help of an ordered pair of numbers also known as coordinates.
The line segment BD is parallel to segment XY
We have to find the value of y
The angle 67 degrees and y are opposite to each other.
So the value of y is 67 degrees
The opposite angles are equal
The value of Y is 67 as angels that are opposite to each other are equal so the angle below Y is 67.
Knowing that we can say that Y is 67 as angels parallel to each other are also equal.
Hence, the value of y is 67 degrees when linesegment BD is parallel to XY.
