This is the concept of probability and statistics, to get the summation of (x-μ) where μ is the mean will be given by:
(3.7-11)+(8.2-11)+(9.9-11)+(9.9-11.3)+(15.6-11)+(17.3-11)
=-7.3+-2.8+-1.1+0.3+4.6+6.3
=0
The answer is 0
The answer would be C.
To find the density take Mass and divide by Volume
Mass
--------
Volume
82.0 g
---------
12.8 cm^<span>3
you get 6.4 g/cm^3</span>
7ft if 3+1/3 hopefully this helps i did hwat i can
