Answer:
I believe the answer is 12, with 9 remaining students.
The IQR is q1-q3! Put the numbers in order, least to greatest. then find the quartiles.
1) <span>Which of the following shows that polynomials are closed under subtraction when polynomial x + 5 is subtracted from 3x2 + 2x − 6?
3x^2+2x-6-(x+5)=3x^2+2x-6-x-5=3x^2+x-11
Answer: Second option: </span><span>3x^2 + x − 11 will be a polynomial
2) </span><span>Which of the following shows that polynomials are closed under subtraction when polynomial 3x2 + 4 is subtracted from x2+ 2x + 5?
x^2+2x+5-(3x^2+4)=x^2+2x+5-3x^2-4=-2x^2+2x+1
Answer: Third option </span><span>−2x^2 + 2x + 1 will be a polynomial</span>
