all students = 150
M = 60
S = 45
M and S = 25
(a) At least one of the two requirements:
M or S = M + S - (M and S) = 60 + 45 - 25 = 80
(b) Exactly one of the two requirements:
(M or S) - (M and S) = 80 - 25 = 55
(c) Neither requirement:
(all students) - (M or S) = 150 - 80 = 70

#3. Plugging the point (3,0) into any of the equations except the third one gives an invalid answer.
Answer:
There are 12 sections, out of the 12 sections the third section is marked. So that would be, 3/12 which simplifies to 1/4
Answer: The correct answer is the second choice: "When any two polynomials are added, the result is always a polynomial."
When a set of numbers is "closed" under an operation, it means that the resulting output answer is the same type as the input.
For example, if you add 2x + 9 and 3x + 12, you get 5x + 21.
You started with 2 polynomials and you ended with a polynomial.
