Find the lengths AB, BC and AC.
length AB= √(4²+(-4)²) = √32
length BC = √(4²+7²) = √65
length AC = √(8²+3²) = √73
From the lengths of this triangle it can be seen that no side is equal to the other and also it is not a right triangle.
So, triangle ABC is a scalene.

that's the answer. you need to group the like terms
The formula for the sum of the squares of the deviations is
SS = s² (N -1)
We are given
SS = 316
N = 9
Substituting
316 = s² (9 - 1)
Solving for s
s = 6.28
The standard deviation is 6.28
Hi! =)
So,<em> 1 </em>lbs per week are equal to<em> 7.4999e-7</em> kilograms per second. We can use this to convert lbs per week to kg per second.
<em>721 * 7.4999e-7 = 0.000540741!</em> =)
