Answer:
Arrival rate, λ = 4 per hour
Service rate = 1/service time = (1 / 9 minute) * 60 minutes per hour = 20/3 = 6.67 per hour
a) Average number of trucks in system, L = λ/(μ-λ) = 4 / (20/3-4) = 1.5 trucks
b) Average time spent in the system, W = L/λ = 1.5/4 = 0.375 = 0.38 hour
c) Total system cost per day = (2*18 + 75*1.5) *8 = $ 1188 per hour
d) New service rate, μ' = (1/7 minutes) *60 minutes per hour = 8.57 per hour
Average number of trucks in system, L = λ/(μ'-λ) = 4/ (60/7 - 4) = 0.875 = 0.88 trucks
e) Average time spent in the system, W = L/λ = 0.875/4 = 0.2187 = 0.22 hour
f) Total system cost per day = (2*18 + 90*0.88) *8 + 200 = $ 1121.6 = 1122 per day
g) Based on above cost analysis, we see that Total system cost per day is lesser in after the new equipment is installed. Therefore, it is worth to install the new equipment.

Incomplete question. The options read;
a) Assess the external labor market
b) Create a replacement chart
c) Forecast internal supply
d) Conduct a job analysis
Answer:
<u>a) Assess the external labor market</u>
<u>Explanation:</u>
<em>Remember</em>, by assessing the external labor market, one can find determine groups that are underrepresented in the labor market. In other words, the groups that are minorities can then be identified from among the external labor market.
For example, if you discover that <em>"</em><em><u>ethnic or social group A"</u></em><u>,</u> has been under-represented or hold little higher-level positions in the external labor market for a number of years, you can now forecast positions where these minority groups could be staffed in the firm.
Answer:
Explanation:
Raw data (in $):
August September
Sale 235,000 1.3 × 235,000 = 305,500
- Cash collected 40% 60% of 235,000
40% of 305,500
Purchase 185,000 205,000
- Cash paid 30% 70% of 185,000
30% of 205,000
Beginning cash balance on September 1: $8,600
<u>Calculations: </u>
The change of the cash balance on September will be the cash collected during the month less the cash paid during the month:
- Cash collected: 60% × $235,000 = $141,000
40% × $305,000 = $122,200
- Cash paid: 70% × $185,000 = $129,500
30% × $205,000 = $61,500
<u>Ending cash balance of September 30:</u>
- Beginning cash balance + cash collected - cahs paid
- $8,600 + $141,000 + $122,200 - $129,500 - $61,500 = $80,800
