Mean, Median, Mode, Range, and Standard Deviation
Range = the largest number - the smallest number in the data
(Arithmetic) Mean = the average of the data set
Mode = the number that appears the most frequent in the data
Median = the middle number in the data set
6
Use Pascal's triangle to expand (2x-1)^4
16x^4 - 32^3 + 24x^2 - 8x
=16x^4 - 32x^3 + 24x^2 - 8x + 1
14x^4 - 32x^3 + 24x^2 - 8x + 1
16x^5 - 32x^4 + 24x^3 - 8^2 + 1x
7
Expand (x+2)
6
using Pascal's Triangle
(x+2)+(x+2)+(x+2)+(x+2)+(x+2)+(x+2)
x6+12x5+60x4+160x3+240x2+192x+64
x6-12x5+60x4-160x3+240x2-192x+64
(x+2)(x+2)(x+2)(x+2)(x+2)(x+2)
