Answer:

The Expected time a customer spends in the system is 4

Explanation:

According to the given data we have the following:

Arrival rate A = 1 every other minute = 30/hour or (30/60) per minute

Service rate S = 84 seconds = 60×60/84= 42.86 customers per hour

System utilization factor P = A/S = 30/42.86 = 0.699

Length of the system L = P/(1-P) = 0.699/(1-0.699) = 2.322

Therefore, Expected time a customer spends in the system = L/A = 2.322/(30/60) = 4.644=4

The manager of a publishing company plans to give a $23,000 bonus to the top 12 percent, $10,000 to the next 25 percent, and $6,
I am Lyosha [343]

Answer:

total expected bonus = $1262800

Explanation:

given data

bonus = $23,000

Probability = 12 percent

bonus =  $10,000

Probability = 25 percent

bonus =  $6,000

Probability = 8 percent

total sales = 220

solution

first we get probability for bonus amount = $0

probability = 1 - ( 12% + 25% + 8 % )

probability =  0.55

so here Expected bonus per employee company will pay is

Expected bonus = $23000 × (0.12) + $10000 × (0.25) + $6000 × (0.08) + $0 (0.55)

Expected bonus = $5740

so total expected bonus is

total expected bonus = $5740  ×  220

total expected bonus = $1262800
