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:
I do not know the equations given but here's my equation and solution:
9x = 174°
x = 19 1/9°
Step-by-step explanation:
(3x + 2) + 2(3x + 2) = 180°
3x + 2 + 6x + 4 = 180°
9x + 6 = 180°
9x = 174°
x = 19 1/9

Answer:
x=-10
Step-by-step explanation:
the picture is showing
1+1= -1 + -1 + -1 + -1 + -1 + -1 + -1 + -1 + -x
simplified its:
2= -8 + -x
I think that the answer is x=-10 cuz if u did -8 - -10 then the two negatives make a positive and it makes 2 but idk if the minus sign before the x means minus or negative so this might be the answer but dont blame me if im wrong. I warned you. If its right plz write that.
