Answer:
20 miles (Answer B)
Step-by-step explanation:
The northbound biker travels (4 mph)(4 hr) = 16 mi, and
the eastbound biker travels (3 mph)(4 hr) = 12 mi.
They travel at right angles to one another. Thus, the Pythagorean Theorem applies here. The distance between the two bikers is d = √( [12 mi]^2 + [16 mi]^2 ), or √(144 + 256) mi, or √400 mi, which works out to 20 miles.
Answer B is correct.
Answer:
How many closets?
Step-by-step explanation:
We assume that male and female births are equally likely, it means that the probability of birth of male= probability of birth of female = 100%/2=50% or 0.5We have 2 independent events. So what will be the variants:
Male and FemaleMale and Male Female and Male Female and Female
All four variants are equally likely.Probability of each one is 1/4 = 0.25.So, Result "Female and Female"
are probability = 0.250 --- if round to three decimal places.
Answer:
1.732
Step-by-step explanation:
You are given that claims are reported according to a homogeneous Poisson process
LetX be the waiting time from 0 to second claim
X is Poisson with averageof 3 hours.
We know in a Poisson distribution the mean = variance
Hence average waiting time = mean = 3
This will also be equal to var(x)
Var(x) = mean of Poisson distribution= 3
Hence standard deviation = square root of variance
=
