1. what is the standard deviation for the following set of numbers?
2.4.5.5.6,8
a. 2.35
c. 1.54
b.3.67
d. 1.80

D. 1,80

Step-by-step explanation:

To solve this first we need the formula for standar devation

s=sqrt((n(∑x²)-(∑x)²)/n(n-1)

Then we need ∑x and ∑x²

∑x=2+4+5+5+6,8=22,8

∑x²=2²+4²+5²+5²+6,8²=116,24

s=sqrt((5(116,24)-(22,8)²/5(5-1)

s=sqrt(3,058=

s=1,75=1,8

i think that you should ask google for the answer to that problem because if we don't know it google does

step-by-step explanation: the answer is 27. first multiply .32 by 25 which equals 8. then add 8 to 25 which gives you 33. then you subtract that from 6 since she gave 6 to her brother.

,, add !
