The answer would be 72x + 12 but I’m not sure but that’s what I got
The answer is (c). The picture shows that all of the angles and sides are equal, meaning that it's both equilateral and equiangular.
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:
41.1
Step-by-step explanation:
It was decreased by 26.7 between noon and midnight.
If it was -14.4 at midnight, which i after noon, you minus 26.7 and -14.4.
26.7--14.4 is 41.1.
(- and - = +)
