In a certain country, the true probability of a baby being a boy is 0.519. Among the next nine randomly selected births
yawa3891 [41]

Answer:

0.9973

Step-by-step explanation:

Given :

Probability of girl, probability of success , 1 - p = 1 - 0.519 = 0.481

1 - p = 0.481

n = 9

Probability that atleast one is girl

Usingbthe binomial probability distribution :

P(x =x) = nCx * p^x * (1 - p)^(n - x)

USing the binomial probability calculator :

p(x ≥ 1) = p(x=1) + p(x=2) + p(x=3) + p(x=4) + p(x=5) + p(x=6) + p(x=7) + p(x=8) + p(x=9)

p(x ≥ 1) = 0.9973 ( from calculator).

Find the distance between the pair of points.(-5, -8) and (4,4). What is the distance?
Mekhanik [1.2K]

Answer:

label a graph doing -5,-8, and 4,4  use the formula which is

d = ( x 2 − x 1 )^2 + ( y 2 − y 1 )^2

 x2-x1 = 4–2= 2 Y2–Y1 = 1–3 = -2 d=√(2)^2+(-2)^2 =√4+4 = √8 d= 2√2

so this is the same thing the person above me did but I've been typing this out so long I want to go ahead and submit anyway
