Hello User,
The range is the difference highest and lowest values in a set of numbers.
Example:
1,2,3,4,5
Solution:
5-1=4

Answer:
- 6(x^2 +18z +81) . . . as written
- 6(x +9)^2 . . . . . . . . assuming a typo
Step-by-step explanation:
As the expression is written, the only factoring that can be done is to factor out the common numeric factor of 6:
= 6(x^2 +18z +81)
__
<em>Assuming a typo in the question</em>
If we assume all variables are supposed to be "x", then the quadratic term can be further factored as a square:
= 6(x +9)^2
_____
It is often handy to remember that the form of the square of a binomial is ...
(a +b)^2 = a^2 +2ab +b^2
Here, we recognize that 18 = 2√81, so the binomial is (x +√81) = (x +9).
What is the other part of it with the numbers?

Answer:
Cov(X, Y) =0.029.
Step-by-step explanation:
Given that :
The noise in a particular voltage signal has a constant mean of 0.9 V. that is μ = 0.9V ............(1)
Also, the two noise instances sampled τ seconds apart have a bivariate normal distribution with covariance.
0.04e–jτj/10 ............(2)
Having X and Y denoting the noise at times 3 s and 8 s, respectively, the difference of time = 8-3 = 5seconds.
That is, they are 5 seconds apart,
τ = 5 seconds..............(3)
Thus,
Cov(X, Y), for τ = 5seconds = 0.04e-5/10
= 0.04e-0.5 = 0.04/√e
= 0.04/1.6487
= 0.0292
Thus, Cov(X, Y) =0.029.
