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.

Im pretty sure its b im soo sorry if im wrong.
Answer:B
Step-by-step explanation:
Prime Factors of 504: 2, 3, 7
23 × 32 × 71 where 2, 3, 7 are prime.
well, if we try to plot and conect them, we will get square, so the answer is d
