All u have to do is find what variable will make each statement true, I'll do one so u would get what I mean,
61. x + 13.5 < 19, this could be anything under 19 since it's supposed to be greater, I chose 5 + 13.5 < 19 which is 18.5 < 19
The number goes from 13.5 to 19 you could do it like decimals, start it from 13 then go on like this, 13,13.5,14,14.5,15,15.5,16,16.5,17,17.5,18,18.5,& 19.
You can not solve this because the values are different... If the values were both Px and Px or Qx and Qx you will be able to solve the problem but you can not according to the fact that they aren't the same letters. So therefore, this equation has no solution.
Hope this helped!!!
Answer:
z=3
Step-by-step explanation:
Add 3z and 2z
5z-5=25-5z
Add 5z on both sides to eliminate the -5z on the RHS
10z-5=25
Add 5 on both sides to eliminate the -5 on the LHS
10z=30
Divide by 10
z=3
Hope this helps!
I believe the correct answer is a hope this helps if not then sorry
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
