Brainliesttt asap! me : )

describe the center and spread of the number of books read by students in mr. chen’s class using either the mean and standard deviation or the five-number summary. justify your choice using the histogram. round to the nearest tenth if necessary.

answer options:
a. the distribution is symmetric, so use the mean and standard deviation.
mean: 5.2, standard deviation: 2.4

b. the distribution is skewed, so use the five-number summary.
range: 8, median: 4.5, half of the data are between 3 and 7

10% of increase is the final answer! : )

(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
