Answer:
a) 3.6
b) 1.897
c)0.0273
d) 0.9727
Step-by-step explanation:
Rabies has a rare occurrence and we can assume that events are independent. So, X the count of rabies cases reported in a given week is a Poisson random variable with μ=3.6.
a)
The mean of a Poisson random variable X is μ.
mean=E(X)=μ=3.6.
b)
The standard deviation of a Poisson random variable X is √μ.
standard deviation=S.D(X)=√μ=√3.6=1.897.
c)
The probability for Poisson random variable X can be calculated as
P(X=x)=(e^-μ)(μ^x)/x!
where x=0,1,2,3,...
So,
P(no case of rabies)=P(X=0)=e^-3.6(3.6^0)/0!
P(no case of rabies)=P(X=0)=0.0273.
d)
P(at least one case of rabies)=P(X≥1)=1-P(X<1)=1-P(X=0)
P(at least one case of rabies)=1-0.0273=0.9727
Answer:
The correct method for recording numerical information from an experiment is the quantitative method.
Step-by-step explanation:
This method represents the way of recording that tracks variables (sometimes more than one) and how they interact with each other. This will help to establish relationship within your experiment.
Answer:
for 1 in the right side, corresponding is 3, for 2, you get 4, for 6, you get 8, and for 7, you get 9. pls follow and mark as brainliest

Answer:
Step-by-step explanation:
You're looking for the circumference here, which is the distance around the outside of a circle. The formula is
C = πd or C = 2πr
Since we are given the diameter, we will use that one:
C = (3.14)(18) so
C = 56.5 feet
Answer:
below
Step-by-step explanation:
l = large no
s = small no
l=s+13
l+s = 67
s+13+s = 67
2s+13 = 67
2s = 54
s=27
l= 40
