Given that variance of a data set is:
Variance=σ²
the standard deviation is the square root of the variance:
thus
standard deviation= √(variance)
variance,σ²=104.04
thus
std deviation=√σ²=√104.04
thus
σ=10.2

Answer:
(m º n)(x) = x -2
Step-by-step explanation:
Here, in the given expression:
m(x)= x+1 and n(x) = x - 3
To find : (m º n)(x)
Now, solving for (m º n)(x)
(m º n)(x) = m (n (x)) = m (x-3)
also, m (x-3) = (x -3) + 1 = x -2
So, (m º n)(x) = x -2
