The random variable x is the number of occurrences of an event over an interval of ten minutes. It can be assumed that the proba
mart [117]

Answer:

The probablility that there are 8 occurrences in ten minutes is 0.00518 or 0.5%.

Step-by-step explanation:

The distribution that represents the ocurrence of this events is the Poisson distribution.

The probability of having k events in a ten-minute-period can be expressed as:

P(x=k)=\frac{ \lambda^ke^{-k}}{k!}

being λ the mean number of occurrences in ten minutes.

The probablility that there are 8 occurrences in ten minutes can be calculated as:

P(x=k)=\frac{ \lambda^ke^{-k}}{k!}\\\\P(x=8)=\frac{5.3^8e^{-8}}{8!}=\frac{(622596*0.000335463)}{40320}=0.00518

The probablility that there are 8 occurrences in ten minutes is 0.00518 or 0.5%.

Please answer question D for me!
Nesterboy [21]

Answer:

I think its 55.

Step-by-step explanation:

So, the mean of it at first is 185, so that means you can do 185 x 6 = 1100 since there is 6 different types.

But, since the Blue Spruce is added there will be 7, so you can do 165 x 7, which gives you 1155. From there I would do 1155-1100 = 55

A university cafeteria line in the student center is a
nirvana33 [79]

Answer:

Lamda= 4 students/min, µ= 5 students/min  

P= Lamda/µ= 4/5= 0.8

a.) Probability that system is empty= P0= 1-P= 1-0.8= 0.2

b.) Probability of more than 2 students in the system= ∑(n=3 to inf) P^n*P0= (1-P)*(1/(1-P) – (1-P) –(1-P)*P –(1-P)*P^2)= (.2)*(5-  - .2 - (.8)*.2 – (.2)*.8^2))= 0.848

Probability of more than 3 students in the system= ∑(n=4 to inf) P^n*P0= (1-P)*(1/(1-P) – (1-P) –(1-P)*P –(1-P)*P^2 – (1-P)*P^3)= 0.768

c.) W(q)= Waiting time in Queue= lamda/µ(µ- lamda)= 4/5(1)= 0.8 minutes

d.) L(q)= lamda*W(q)= 4*.8= 3.2 students

e.) L(System)= lamda/(µ-lamda)= 4 students.

f.) If another server with same efficiency as the 1st one is added, then µ= 6 sec/student= 10 students/min.

P= 4/10= 0.4

Probability that system is empty= P0= 1-.4= 0.6

W(q)= 4/10(10-4)= 0.0667 minutes

L(q)= Lamda*W(q)= 4*.0667=0.2668

L(system)= Lamda/(µ-lamda)= 4/6= .667

Can you help me with this assignment
Pachacha [2.7K]

In the given figure,

line a & b are parallel, line l and m are parallel.

for line a and b are parallel and line l act as a transversal.

So, angle BAC and ACD are the alterantive interior angles.

Angle BAC = Angle ACD

2x = 46

i.e. Angle BAC = 46

Lines l and m are parallel, a line act as a transversal,

So, the angle BAC and angle y are the corresponding angle,

Since the pair of corresponding angles are always equal so,

Angle BAC = y

46 = y

y = 46

Answer : y = 46
