Answer:

The answer to this question is a= µ=60/12=5 students/min

Explanation:

Solution

Given that:

λ=4 students / min

The Waiting time in Queue= λ /µ(µ- λ )==4/(5*(5-4))=0.8 min

The Number of students in the line L(q)= λ *W(q)= 4*.8= 3.2 students

TheNumber of students in the system L(q)= λ /(µ- λ )=4/(5-40=4 students

Then,

The Probability of system to be empty= P0= 1-P= 1-0.8= 0.2

Now,

If the management decides to add one more cashier with the same efficiency then we have

µ= 6 sec/student= 10 students/min.

so,

P= λ /µ =4/10=0.4

Now,

The probability that cafeteria is empty= P0= 1-0.4= 0.6

If we look at the above system traits, it is clear that the line is not empty and the students have to standby for 0.8 in the queue waiting to place their order and have it, also on an average there are 3.2 students in the queue and in the entry cafeteria there are 4 students who are waiting to be served.

If the management decides to hire one more cashier with the same work rate or ability, then the probability of the cafeteria being free moves higher from 0.2 to 0.6 so it suggests that the management must hire one additional cashier.

Explanation:

Based on the information given we were told that when he received the bill, their was large charges in excess of his maximum out-of-pocket limit which is a limit on the amount of money a person or an individual have to pay for covered medical care services in which we were still told that the large charges in excess of his maximum out-of-pocket limit also include a number of services and items he thought would be fully covered, therefore since he called you to ask what he could do, What you could tell him is that you will offer to help him review all the plans appeal process and to as well help him to ask the plan to review the coverage decision which is why coverage decision is of benefit because it enables a person or an individual to makes decision about their benefits including the amount they have to pay for their medical services plan.

Kay Company budgets overhead cost of $4,104,000 for the next year. The company uses direct labor hours as its overhead allocatio

Kobotan [32]

Based on the fact that Kay Company will use direct labor hours as its overhead allocation base, the overhead for a product with 5 labor hours is $228.

<h3>What is the overhead assigned to the product?</h3>

This can be found as:

= Total overhead cost / Number of labor hours x Product labor hours

Solving gives:

= 4,104,000 / 90,000 x 5

= 45.6 x 5

= $228

If the world's population increased exponentially from 5.937 billion in 1998 to 6.771 billion in 2008 and continued to increase

Vaselesa [24]

Answer:

The world's population would have been 7.1137 billion in 2012, and this is 0.0437 billion (i.e. 7.1137 - 7.07 = 0.0437) higher compared to the population reference bureau estimate of 7.07 billion in July 2012.

Explanation:

This can be computed using the following exponential formula:

P(t) = P(0)a^t ............................ (1)

Where;

P(t) = World population in year t.

P(0) = World population in year 0 which is 1998 = 5.937 billion

a = base = ?

t = number of years

Substituting the value into equation (1), we have:

P(t) = 5.937 * a^t .......................................... (2)

Since we have 10 years from 1998 to 2008 (i.e. 2008 - 1998 = 10), we have:

P(t) = P(10) = World population in 2008 = 6.771 billion

t = 10

Substituting the value into equation (2) and solve for a, we have:

6.771 = 5.937 * a^10

a^10 = 6.771 / 5.937

a^10 = 1.1405

a = $\sqrt[10]{1.405}$

a = 1.013

Since we have 14 years from 1998 to 2012 (i.e. 2012 - 1998 = 14), we now have:

P(t) = P(14) = World population in 2012 = ?

P(0) = World population in year 0 which is 1998 = 5.937 billion

a = 1.013 as already calculated above

t = 14

Substituting the value into equation (1), we have:

P(14) = 5.937 * 1.013^14

P(14) = 5.937 * 1.192

P(14) = 7.1137 billion

Therefore, the world's population would have been 7.1137 billion in 2012, and this is 0.0437 billion (i.e. 7.1137 - 7.07 = 0.0437) higher compared to the population reference bureau estimate of 7.07 billion in july 2012.
