A middle school coach wrote down the time, in seconds, of her students’ 100-meter dash as shown in the table. Student Time -(seconds)
Gary 11.9
Rick 12.3
Phillip 13.5
Jorge 12.0
Robert 12.3
Jeremy 16.0

If the slowest time and the fastest time are removed from the data, how does the new mean compare to the mean of the original data set?

A. The mean would not change as the lowest and greatest values were removed.
B. The mean would increase as there is less variability in the data.
C. The mean would not be comparable as the data sets are different.
D. The mean would decrease as there is less variability in the data.

(x3 + 6x2 + 2x - 6) • (x - 1)

step-by-step explanation:

polynomial long division :

3.2     polynomial long division

dividing :   x4+5x3-4x2-8x+6

                              ("dividend")

by         :     x-1     ("divisor")

dividend     x4   +   5x3   -   4x2   -   8x   +   6

- divisor   * x3     x4   -   x3            

remainder         6x3   -   4x2   -   8x   +   6

- divisor   * 6x2         6x3   -   6x2        

remainder             2x2   -   8x   +   6

- divisor   * 2x1             2x2   -   2x    

remainder               -   6x   +   6

- divisor   * -6x0               -   6x   +   6

remainder                     0

quotient :   x3+6x2+2x-6   remainder:   0

none cuz there are no "following statements" regarding the question
