Answer:
4 ; 32
Step-by-step explanation:
Given that :
Number of observations, n = 9
Let observations = X
ΣX = 360
The mean, (m) is calculated using the formula :
m = ΣX / n
m = 360 / 9
m = 4
Σ(X - m) = 288 (sum of square of deviation )
Variance is calculated using the formula :
[Σ(X - m) / n]
Variance = Sqrt(288 / 9)
Variance = 32
Answer:
if you're talking about eifell tower is 984′, 1,063′ to tip
Step-by-step explanation
Putting this in mathematical terms
(-5)x/2-5=-55
Multiplying throughout by ‘-1’
(5x)/2+5=55
5x/2=50
x=+20
Thus 20 is the required value of x.
