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.
Answer:
20x^5
Step-by-step explanation:
You just multiply 5 by 4 and get 20 and when multiplying exponents you just add them together so you get 20x^5
Answer:
Yes
Step-by-step explanation:
10:12 and 30:36
you can simplify them first so
10:12=5:6
and
30:36=5:6 which is equivalent to the other ratio
or you can do
10:12
10 times 3 is 30 30:36 12 times 3 is 36
