One thousand and twenty students participated in the school math contest.
a random sample (sample 1) from grades 9 and 10 showed scores of: 72, 89, 67, 81, 75, 79, 81, 80, 62, 64, 83.
a random sample (sample 2) of grades 11 and 12 showed scores of: 84, 86, 87, 84, 86, 89, 90, 87, 87, 84, 86.

what is the median of sample 1?

what is the median of sample 2?

we are given polynomial 2x^2 +4x +7.

we need to determine the number of roots of the given polynomial using the fundamental theorem of algebra.

a) for the given polynomial 2x^2+4x+7, we have degree =2.

b) let us find the roots of the given polynomial.

2x^2+4x+7= 0

y=5

step-by-step explanation:

c minus thirteen equals negative two. to find c add thirteen two both sides. this cancels out the thirteen and gives you eleven on the other side. this leaves you with c equals eleven.
