In May 2011, Gallup asked 1,721 students in grades 5 through 12 if their school teaches them about money and banking. Researchers are interested in finding out if majority of students receive such education. Which of the following are the correct set of hypotheses?

1. when "a" is a root of a polynomial, (x -a) is a factor of it. for the three roots given, the factors of the desired polynomial are (x +2)(x -1/2)(x -3).

in order to make the leading coefficient be negative, we need to multiply this product by a negative number. any negative number will do, but we choose a small (magnitude) value that will eliminate the fraction: -2.

then

f(x) = -2(x +2)(x -1/2)(x -3) = -(x +2)(2x -1)(x -3)

= -(2x² +3x -2)(x -3)

= -(2x³ -3x² -11x +6)

f(x) = -2x³ +3x² +11x -6

2. a graph created by the desmos on-line graphing calculator is shown, and the zeros are highlighted.

3. as indicated in part 1, the multiplier of this equation can be anything and the zeros will remain the same. you want a negative leading coefficient, so the "anything" is restricted to any of the infinite number of numbers that will make that be the case.

false

ok

hope this

the options to this answer are:

a. 97

b. 58

c. 19

d. 39

i believe the answer is 19 but i'm not 100% sure. correct be if i'm wrong! have a super day anyways!
