A Covid-19 vaccine clinic in downtown area of a large city opens 24 hours a day and residents from all over the city may come to the clinic for service. Assume that the arrival process follows Poisson distribution with an average of 5 arrivals per hour. The average time required to give the vaccine is 8 minutes and the service time follows exponential distribution. Use the standard single channel single stage queuing model introduced in class and equations given below to calculate corresponding values in answering the following questions. 1) Estimate the number of hours that the staff at the clinic are busy in a 12 hour time period 2) Estimate the time a person coming to the clinic is expected to wait to get served after he/she arrives. 3) Estimate the time a person is expected to spend in the clinic (including waiting and being served) after he/she arrives. 4) There is a seat in the clinic for the patient/person to sit down when he/she is treated. The clinic decided that at least 75% of the time that a patient/person waiting to be served should have a seat and prepared 2 chairs in the waiting area. Use given information and formula to estimate if these 2 chairs in the waiting area are enough to meet this 75% target. Note that the formula of P(n) given below is to calculate the probability that there are n customers in the system including the one being served and those waiting.

Answers
1.The staff at the clinic will be busy for 12 x 0.625 = 7.5 hours in a 12-hour time period.
2. The expected waiting time is 0.444 minutes.
3. A person is expected to spend 10 minutes in the clinic.
4.The two chairs in the waiting area should be enough to meet the 75% target.
1. To estimate the number of hours that the staff at the clinic are busy in a 12-hour time period, we need to calculate the average utilization of the server. The service rate is the reciprocal of the average service time, so u = 1/8 = 0.125 customers per minute. The arrival rate is given as 5 customers per hour, so λ = 5/60 = 0.0833 customers per minute. The utilization of the server is P(1), which can be calculated using the formula P(1) = (1-λ/u). Therefore, P(1) = 0.625, indicating that the server is busy 62.5% of the time.
2. To estimate the time a person coming to the clinic is expected to wait to get served after he/she arrives, we need to calculate the average waiting time in queue. The formula for the mean waiting time in queue is Ta = λ (u²+1)/(2u(1-u)), which equals to Ta = (0.0833 x (0.125²+1))/(2 x 0.125 x (1-0.125)) = 0.444 minutes.
3. To estimate the time a person is expected to spend in the clinic (including waiting and being served) after he/she arrives, we need to calculate the mean time in the system. The formula for mean time in the system is Ts = 1/(u-λ), which equals to Ts = 1/(0.125-0.0833) = 10 minutes.
4. To estimate if the two chairs in the waiting area are enough to meet the 75% target, we need to calculate the probability of having two or fewer people in the system, including the one being served and those waiting. P(0) = (1-λ/u) = 0.625, and P(1) = λ/u x P(0) = 0.208. Hence, the probability of having two or fewer people in the system is P(0) + P(1) + P(2) = 0.739. This means that 73.9% of the time, there will be two or fewer people in the system, which exceeds the target of 75%.

Draw the cross-sectional effect diagrams for the beam whose loading condition is given in the figure ({N}, {T}, {M})
Answers
A cross-sectional effect diagram, also known as an axial force-shear force-bending moment diagram or simply an internal force diagram, is a graphical representation that shows the distribution of internal forces (axial force, shear force, and bending moment) along the length of a structural member, such as a beam or column.
To draw the cross-sectional effect diagrams for the beam whose loading condition is given in the figure, we need to follow these steps:
Step 1: Identify the type of loadingFor this question, the loading conditions are {N}, {T}, {M}. So, the loading types are axial force, shear force, and bending moment.
Step 2: Draw the cross-sectional diagram of the beam. We need to draw the diagram of the cross-section of the beam in the direction of the forces acting on the beam. In this case, it will be a rectangular beam.
Step 3: Draw the effect diagrams After drawing the cross-sectional diagram, we need to draw the effect diagrams for each loading condition.
The effect diagrams are as follows: 1. Axial force diagram (N):In this case, the axial force is positive (+) which means it is a tensile force. 2. Shear force diagram (T):The shear force is negative (-) from x = 0 to x = 1, which means the shear force is acting downward. It is zero at x = 1 and then becomes positive (+) from x = 1 to x = 2, which means the shear force is acting upward. 3. Bending moment diagram (M):The bending moment is zero at x = 0, becomes negative (-) from x = 0 to x = 1, reaches a minimum at x = 1, and then becomes positive (+) from x = 1 to x = 2.

Does AAS prove triangles congruent?
Answers
Yes, AAS or Angle-Angle-Side proves the triangle is congruent.
What is AAS or Angle-Angle-Side congruence?
According to the AAS congruence rule, any two angles and the excluded side of one triangle must be identical to the corresponding angles and excluded side of the other triangle. The sides are not included between the angles but rather run in either direction of the angles, whilst the angles are sequential and matching in nature. The two adjacent or consecutive angles of one triangle are identical to the corresponding angles of another triangle, as seen in the illustration below. Because the sides of both triangles after the angles rather than included between them, they are also equal.According to the AAS or Angle Angle Side congruence rule, two triangles are said to be congruent if two sets of comparable angles and the opposing or non-included sides are equal.Learn more about AAS congruence from the link below

A system of linear equations is a grouping of one or more linear equations with the same variables. The two-digit number is 75.
What is a system of linear equations?A system of linear equations is a grouping of one or more linear equations with the same variables.
Let the tens digit be represented by x and the unit digit be represented by y.
Given that the sum of the digits in a two-digit number is 12. Therefore, the sum of the two digits can be written as
x + y = 12
x = 12 - y
Also, given that the tens digit is 2 more than the ones digit. Therefore, we can write,
x = y + 2
Equate the value of x from the two equations together,
x = x
12 - y = y + 2
12 - 2 = y + y
10 = 2y
y = 5
Substitute the value of y in the equation of x,
x = 12 - y
x = 7

Answers
The rate of increase of the depth of the water (W(t)) is constant.
What is rate ?
In mathematics and physics, the rate is a measure of change of a certain quantity with respect to another quantity. The rate can be a number, a ratio or a derivative. It is often represented by the symbol "d" or "dx/dt" or "dy/dt" and it measures how fast a quantity is changing.
Water is poured into the top half of a spherical tank at a constant rate, this means that the rate of increase of the depth of the water (W(t)) is constant.
In this case, W(t) is constant.
It is important to keep in mind that the rate of change of the function doesn't indicate the shape of the function, it just tells us the change of the dependent variable with respect to the independent variable. The shape of the function can be visualized by creating a graph of the function.
So , The rate of increase of the depth of the water (W(t)) is constant.

Answers
Gerry's beginning basis in the S corporation is $20,545.
To calculate Gerry's beginning basis in the S corporation, we need to consider the cost of the assets transferred and the additional expenses incurred for the conversion.
The cost of the assets transferred is given as $19,570. This represents the original cost of the assets when Gerry acquired them.
The adjusted basis of the assets is stated as $9,600. The adjusted basis takes into account any adjustments made to the original cost, such as depreciation or other deductions.
To calculate the beginning basis in the S corporation, we add the cost of the assets transferred ($19,570) to the adjusted basis ($9,600). This gives us a total of $29,170.
In addition to the assets, Gerry incurred an additional expense of $975 for the conversion to an S corporation. We include this amount in the calculation of the beginning basis.
Therefore, Gerry's beginning basis in the S corporation is $29,170 + $975 = $20,545.
This beginning basis is important for determining Gerry's tax consequences and future deductions within the S corporation structure.

S = successfully learning the skill
P (A) = 0.75
P (B) = 0.25
P (S|A) = 0.80
P (S|B) = 0.95
Compute the probability that a worker was taught by method A given that he learned the skill successfully as follows:
\(P(A|S)=\frac{P(S|A)P(A)}{P(S|A)P(A)+P(S|B)P(B)}\)
