Below are the points, before and after the translation
A(-2,2) --> (0,-1) B(-2,4) --> (0,1) C(2,4) -->(4,1) D(2,2)--> (4,-1)
Since all vertices were translated using the same rule, the slopes of segments AA', BB', CC', DD' will all be same. So all the joined segments will be parallel to each other

The variance of the binomial distribution of the number of households with landline service is 2.

<h3>What is the binomial probability distribution?</h3>

It is the probability of <u>exactly x successes on n repeated trials, with p probability</u> of a success on each trial.

The variance of the distribution is given by:

V(X) = np(1 - p)

In this problem, the parameters are given as follows:

n = 8, p = 0.504.

Hence the variance is given by:

V(X) = 8 x 0.504 x 0.496 = 2.
