Plzzz help<br> What is the distance between P(-3, -2) and Q(5, -2)?
Yuri [45]
Well first, you have to know the distance formula. You plug the coordinates into it and you get the answer.

\sqrt(-2 + 3) ^{2} + (-2 - 5) ^{2}

√1² + -7² = d

d = 7.1

Suppose the number of children in a household has a binomial distribution with parameters n-8 and p-50%. Find the probability of
Goshia [24]

Answer:

Step-by-step explanation:

Given that the number of children in a household has a binomial distribution with parameters n-8 and p-50%

As per binomial definition we have

P(X=r) = nCr p^r q^{n-r}

=8Cr (0.5)^r (0.5)^{n-r} \\=8Cr(0.5)^8

a) P(x=3 or 7) = P(3)+P(7) = 0.2188+0.0313=0.2501

b) P(X≤5)=0.8555

c) P(X≥3)=0.8555

d) P(x<7) =0.9648
