1 2.8.3 Quiz: Isosceles and Equilateral Triangles Question 7 of 10

What is the length of AB?

B

4x

2x + 6

50°

А

50

wouldn't that be a) 1

4=4x then divide 4 on both sides and you get x=1

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

answer: the best estimate of the mean of the population = 14.

step-by-step explanation:

given: sheri surveyed eighty students, then generated three random samples of twenty-five student responses.

the sample mean=

⇒ the sample mean=

hence, the best estimate of the mean of the population = 14.
