A museum recorded the number of visitors that came each day for 10 days. The data is shown in the table below. Museum Visitors
Day Number of Visitors
1 19,784
2 25,306
3 17,880
4 13,055
5 14,629
6 18,010
7 15,441
8 17,550
9 20,005
10 21,263
Which are the range and the interquartile range (IQR) for the museum’s number of visitors over those 10 days?

A. range: 12,251; IQR: 4,564
B. range: 12,251; IQR: 4,890
C. range: 25,306; IQR: 4,890
D. range: 25,306; IQR: 5,599
Thank You!

typically if you want , you would actually put questions here for us to you. but hey, that's just me. maybe someone will magically answer the questions for you without knowing what they are.

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.

answer: the answer for that is 22/3

i think da answer is

d.square root of 3
