data set : 20 numbers
variance : 36
Find the standard deviation from the mean.
If the variance is already provided, we simply find the square root of the variance to get the standard deviation.
Standard deviation = √36 = 6
The standard deviation of the data from the mean is √variance, which is: 6.
What is Standard Deviation?
The standard deviation can be gotten by finding the square root of the variance of the data. That is, Standard deviation = √variance.
Given the following:
Variance = 36
Standard deviation = √36
Standard deviation from the mean = 6

The nth term of the sequence will be Tn = n^2 + 7n
How to calculate the nth term of a sequence
Given the sequence of numbers expressed as:
8;18;30;44;
Their common difference will form an A P as shown:
10, 12, 14...
Next term = preceding term + 2
Next term = 14 + 2
Next term = 16
The next term of the squence will be 44 + 16 = 60
The nth term of the sequence will be Tn = n^2 + 7n

a(1)=8
a(2)=18=8+10=8+8+2=2*8+2=2*8+2*(2-1)
a(3)=30=18+12=2*8+2*(2-1)+8+2*(3-1)=3*8+2(1+2)
a(4)=44=a(3)+14=3*8+2(1+2)+8+2(4-1)=4*8+2(1+2+3)....
a(n)=n*8+2(1+2+3+...+(n-1))
= 8n+2*n*(n-1)/2)=8n+n(n-1)=n²+7n
n=1=>1²+7*1=8
n=2=>2²+7*2=4+14=18
n=3=>3²+7*3=9+21=30

Alright, lets get started.
We have given that volume of cube depends on the lenght of side.
In cube we know that each side is of similar size.
Suppose the side lenght of cube is a, the volume of that cube will be a^3.
We have given in question notation of volume V(s).
V(3) = 27
Which shows the lenght of side of cube is 3 and the volume of cube is 27, which satisfies the formula also.
3 ^3 = 27 the volume given
So, the best interpretation of V(3) = 27 is the lenght of the cube side is 3 and the volume of the cube is 27. : Answer

Factor the possible ones to be easier
[4a(a+1)]/[(a-5)(a+5)] x [a(a-5)/8a]
Cancel the a-5
[4a(a+1)]/[a+5)] x a/8a
cancel the 4a and 8a(8a becames 2)
[a+1]/[a+5] x a/2
now multiply
[a(a+1)]/[2(a+5)]<---- can be the answer or:
(a^2+a)/(2a+10)
