Question 3
1 pts
The grades on a math midterm at Gardner Bullis are roughly symmetric with
h=76 and o = 4.5
Daniel scored 64 on the exam.
Find the z-score for Daniel's exam gradė. Round to two decimal places.

nswer: a   y-axis

step-by-step explanation:

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.

answe: it will take 4.5 hours for naomi and clair to paint an equal number of square feet

i believe so, according to my "strange" way of figuring out weird math problems like this.
