AVI supplies vended food to a large university. Because students kick the machines at every opportunity, management has a consta

nt repair problem. The machines break down on an average of three per hour, and the breakdowns are distributed in a Poisson manner. Downtime costs the company $25/hour per machine, and each maintenance worker gets $4/hour. One worker can service machines at an average rate of five per hour, distributed exponentially; two workers working together (as one team) can service seven per hour, distributed exponentially; and, a team of three workers can do eight per hour, distributed exponentially. What is the optimum maintenance crew size?

Answer:

The optimum maintenance crew size is 2 workers.

Explanation:

M/M/1 model for all: -

With one worker: λ= 3 per hour.

µ= 5 per hour.

Average number in system = λ/µ-λ =\frac{3}{5-3} = 1.5.

- With two workers: λ= 3 per hour µ= 7 per hour.

Average number in system = λ/µ-λ−=\frac{3}{7-3}=0.75.

- With three workers: λ= 3 per hour, µ= 8 per hour.

Average number in system = λ/µ-λ−=\frac{3}{8-3}=0.6.

# workers       λ      µ     (ns)    ($25*(ns))    ($4*(no.of workers)     Total cost

      1                3      5      1.5       37.50                         4                          $41.50

      2               3      7      0.75     18.75                         8                         $26.75

      3               3      8      0.6        15                             12                        $27.00

The optimum maintenance crew size is 2 workers.

Paula Reid is the manager at the Miami office of the U.S. Secret Service who set in motion a major prostitution scandal by repor
Elan Coil [88]

Answer:

The answer is: She used the justice approach, realizing that the greater good is served because people learn to help each other in their own interest.

Explanation:

Justice approach: an ethical decision is a decision that distributes benefits and costs (or punishments) among those involved in a fair, equitable, and impartial way.

Paula used this approach because she believed the agents had acted improperly and that they were harming the US Secret Service.

I consider any organization a team, so in order for it to work well its members must be respected both by their peers and by the other teams´ members. If you consider the various types of activities this specific agency carries out, other not so friendly "teams" (other secret services or even terrorists) could use this type of information to damage or compromise those activities. So the well being of all the country was being jeopardized by a group of bad agents.

Auagaa474 Corporation had sales of $491,300 and average operating assets of $289,000 for the past period. What is the margin tha
astra-53 [7]

Answer:

16%

Explanation:

Calculation for the margin that Auagaa474 needed to earn in order to achieve an ROI of 27.2%

First step is to calculate the Turnover using this formula

Turnover = Sales ÷ Average operating assets

Let plug in the formula

Turnover= $491,300 ÷$289,000

Turnover=1.7

Now let calculate the margin using this formula

ROI = Margin × Turnover

Let plug in the formula

27.2% = Margin × 1.7

Margin = 27.2% ÷ 1.70

Margin=0.16*100

Margin= 16%

Therefore the margin that Auagaa474 needed to earn in order to achieve an ROI of 27.2% will be 16%

crimeas [40]

A symmetric, bell-shaped frequency distribution that is completely defined by its mean and standard deviation is the<u> normal distribution.</u>

A symmetrical distribution about the mean, such as the normal or Gaussian distribution, indicates that data points closer to the mean occur more frequently than data points further from the mean.

The normal distribution is represented graphically by a bell curve. A bell curve of probabilities is more properly known as the normal distribution. The standard deviation is one and the mean is zero in a normal distribution. Its kurtosis is 3, and its skewness is 0. Not all symmetrical distributions are normal, but all normal distributions are symmetrical. The normal distribution can be thought of as a rough approximation of many naturally occurring events. However, most price distributions in finance are not normally distributed.

<u></u>

To know more about normal distribution refer to:
