Complete the table of values for the equation y=x2-2x-1

lord [1]

y = x^2 - 2x - 1

1. If x = -2, then

y = (-2)^2 - 2(-2) - 1

= 4 + 4 - 1

= 7

2. If x = 0, then

y = (0)^2 - 2(0) - 1

= 0 - 0 - 1

= -1

3. If x = 2, then

y = (2)^2 - 2(2) - 1

= 4 - 4 - 1

= -1

4. If x = 3, then

y = (3)^2 - 2(3) - 1

= 9 - 6 - 1

= 2

Hope you could understand.

Pls help me

rjkz [21]

Answer:

the MAD to this set is 6.75

Step-by-step explanation:

The process is pretty long on how to find the MAD but here it goes.First you find the mean of the set( 70 )then you find the distances between all the numbers and the mean( 68 is 2 values away from being 70 so that would be 2) than you add all the distances together than divide that number by the amount of values are in the set.

hope that makes sense have a good day

In electrical engineering, the unwanted "noise" in voltage or current signals is often modeled by a Gaussian (i.e., normal) dist

vladimir1956 [14]

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.

Find the Range and Domain of the Binary relations

sukhopar [10]

Answer:

A = {3,5,6}

B = {1,3}

A x B = {(3,1),(3,3),(5,1),(5,3),(6,1),(6,3)}

Domain of A x B = (The x figures in ascending order)

=> {3,5,6} (Figures repeating more than once must be written only 1 time)

Range of A x B = (The y figures in ascending order)

=> {1,3}

B x A = {(1,3),(3,3),(1,5),(3,5),(1,6),(3,6)}

Domain of B x A = {1,3}

Range of A x B = {3,5,6}
