1. Calculate the variance of the set of data to two decimal places. {

a. 22
b. 4
c.3.14
d. 1/7
e.2

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18

4

step-by-step explanation:

im pretty sure it's 4 beacsue 8/2 equals 4
