Answer:
The correct answer is Recency error.
Explanation:
Focus on the most recent performance evaluated: The evaluators can be guided by the most recent actions and / or attitudes, whether negative or positive, without considering the history of the collaborators. This error can give an unfair result and nothing representative.
A recency error is an inaccuracy or failure in the performance evaluation or job interview, caused by the dependence of the evaluator or the interviewer on the most recent events of the employee or applicant behavior.
Answer:
E. I, II, and IV only
Explanation:
Six sigma is a management technique that involves measuring the number of defective products resulting from production activities, and carefully undergoing certain processes to reduce these defects and improve quality.
The DMAIC cycle is an important process when using the six sigma technique. It involves;
• Defining the goals and objectives to be achieved and problems to be fixed.
• Measuring the production process to see how it currently performs and gathering data on defective products.
• Analysing the processes to find root causes of problems and possible causes of defects.
• Improving the process by implementing carefully formed plans which will help reduce defects.
• Controlling how the new processes are implemented to yield and sustain favorable results and deliver value to customers.
Six sigma aims to remove variations from business processes to reduce product defects and improve quality.
Answer:
They should operate Mine 1 for 1 hour and Mine 2 for 3 hours to meet the contractual obligations and minimize cost.
Explanation:
The formulation of the linear programming is:
Objective function:
Restrictions:
- High-grade ore: 
- Medium-grade ore: 
- Low-grade ore: 
- No negative hours: 
We start graphing the restrictions in a M1-M2 plane.
In the figure attached, we have the feasible region, where all the restrictions are validated, and the four points of intersection of 2 restrictions.
In one of this four points lies the minimum cost.
Graphically, we can graph the cost function over this feasible region, with different cost levels. When the line cost intersects one of the four points with the lowest level of cost, this is the optimum combination.
(NOTE: it is best to start with a low guessing of the cost and going up until it reaches one point in the feasible region).
The solution is for the point (M1=1, M2=3), with a cost of C=$680.
The cost function graph is attached.
Answer:
D) Buyer
Explanation:
The buyer is responsible for developing the technical specifications of the product that is going to be purchased, inviting potential vendors, and will also be the person in charge of actually executing the purchase. The buyer is the person that has the actual authority and is responsible for carrying out the purchase.
Most likely a two year college, so a local community college nearby is a good option. It's also a lot cheaper than a traditional university.
