Answer:
the perimeter of the square is 4√2
Step-by-step explanation:
With this being a square, we know that the distance from (0, 1) to (1, 0) is
√[ (1)² + (-1)² ], or √2.
There are four line segments, all of length √2, so the perimeter of the square is 4√2.

Step-by-step explanation:
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.
X|59|46|24|24
Y|48|38|38|26
