Answer:
0.632 ; 0.233
Step-by-step explanation:
Given that :
Conversation average λ = 1/5 = 0.2
Using the poisson distribution function :
P(x) = 1 - e^(-λ/x)
p(< 5) = 1 - e^-(1/5 * 5)
P(<5) = 1 - e^-1
P(< 5) = 1 - 0.3678794
= 0.6321205
= 0.632
B.) between 5 and 10 minutes
5 < x < 10
P(x< 5) - p(x< 10)
P(< 5) = 1 - 0.3678794 = 0.6321205
P(< 10) = 1 - (e^-1/5 * 10)
P(< 10) = 1 - e^-2 = 1 - 0.1353352 = 0.8646648
P(< 10) - P(<5)
0.8646648 - 0.6321205
=0.2325443
= 0.233
Answer:
P-15>18
P>33
Step-by-step explanation:
First, you need to make the equation. Knowing that deference means you need to subtract, you write it out. P-15>18 . Then to solve it, you add the 15 over to the other side. 18+15=33, therefore p>33
Because they dont have variables
J = 2mn
just plug in the values they give you
24 = 2(m)(3)
24 = 6m
now divide both sides by 6
4 = m
