Answer:
E) Any of the above may be possible.
Explanation:
Negative feedback means any of following reasons are possible:
1. The decision was a bad one (most probably)
2. More information and new suggestions should be incorporated since the more input better will be the output
3. More time, resources, effort and thought are needed
4. Manager may have to re-start the decision process from beginning
Answer:
A.
0.833
Explanation:
m = 3
Arrival rate, ra = 45 per hour
Service rate, re = 18 per hour per lane
Utilization factor = ra/(m.re)
= 45/(3*18)
= 0.833
Therefore, The utilization factor of the system is 0.833
Dupe's present age = 14 years
Olu's present age = 11 years
Explanation:
- Let Dupe's age be x. Let Olu's age be y. Since their ages add up to 25 years, x + y = 25
- Eight years ago Dupe's age was double that of Olu's age. Solving by simultaneous equations. Four methods are Elimination Method, Graphical Method, Substitution Method, and Matrix Method. Let us try out Elimination method for solving a pair of simultaneous linear equations that reduces one equation to one that has only a single variable. Once this has been done, the solution is the same as that for when one line was vertical or parallel.
- Therefore, eight years ago, Dupe's age was 6 and Olu's age was 3 so that x=2y becomes, 6=2*3. Eight years hence, x=6+8=14 and y=3+8=11. That makes, x or Dupe's age as 14 years and y or Olu's age as 11 years.
Answer:
B) greater than $30 but less than $40
Explanation:
the options are missing:
A) less than or equal to $30
B) greater than $30 but less than $40
C) greater than $40 but less than $50
D) greater than $50
we must first calculate safety stock = (Z-score x √lead time x standard deviation of demand) + (Z-score x standard deviation of lead time x average demand)
- Z-score for 98% confidence level = 2.326
- standard deviation of demand = 30
- √lead time = √5 = 2.23607
- we are not given any standard deviation of lead time, so we can assume that it is 0
safety stock = (2.326 x √2.23607 x 30) + (2.326 x 0 x 300) = 156.03 ≈ 156 units
the annual holding cost of 156 units = 156 x $0.25 = $39
