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.

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.

what's the question?

step-by-step explanation:

there is no question.

step-by-step explanation:

idk the answer i want to say 10 but then it would be equal so try 9 but then yeah so yeah we love edgen

she was supposed to add the hours(38.5) and multiply the amount of money she earned(7.50) resulting in $288.75 .

correct me if i'm wrong and if it is i'm truly sorry.
