If -x²+8x-16=0 what is "x"

X=4

x=0

Step-by-step explanation:

  Pull out like factors :

  8x - 16  =   8 • (x - 2)

 (x3) -  8x • (x - 2)  = 0

Pull out like factors :

  x3 - 8x2 + 16x  =   x • (x2 - 8x + 16)

Mean = 2.21

Median = 2

Step-by-step explanation:

The total frequency is 4 + 8 + 6 + 1 = 19.

The mean is the average (total days per total orders):

(4×1 + 8×2 + 6×3 + 1×4) / 19 = 2.21

Since there are 19 orders, the median is the 10th order, which took 2 days to ship.
