The Quality Control Manager at a Credit Card Collection Center is concerned about how many complaints the company is getting from customers. The following data were collected for 15 days of operation: Sample Number: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 Number of Complaints: 12 3 4 6 4 6 7 5 14 4 12 3 1 9 10 Determine lower and upper control limits for the number of complaints they should expect each day using three-sigma limits.

5050 i think

step-by-step explanation:

i dont understand

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.
