Drying times for newly painted microwave oven cabinets are normally distributed with a mean of 2.5 minutes and a standard deviat

ion of 0.25 minutes. After painting, each cabinet is mated with its electronic modules and mechanical components. The production manager must decide how much time to allow after painting before these other components are installed. If the time is too short, the paint will smudge and the unit will have to be refinished. If the time is too long, production efficiency will suffer. A consultant has concluded that the time delay should be just enough to allow 99.8% of the cabinets to dry completely, with just 0.2% ending up being smudged and sent back for refinishing. Given this information, for what time setting should the production manager set the automatic timer that pauses the production line while each cabinet dries?

Answer: 3.22

Explanation:

Given that;

mean = 2.5 min

standard deviation = 0.25 min

now to get the value of X required, we say

z = (x - u) / a

where z is the distance from the mean measured in the standard deviation units, x is the value we are interested in, u is the mean distribution, a is the standard deviation of the distribution.

the time delay should be just enough to allow 99.8% of the cabinets to dry completely = 99.8/100 = 0.9980

first we determine an appropriate z value.

Using the standardized normal tables,

value of z for approximately 0.9980 is 2.88

so using our initial equation z = (x - u) / a

we substitute the value

z = (x - u) / a

2.88 = ( x - 2.5) / 0.25

2.88 * 0.25 = x - 2.5

0.72 = x - 2.5

x = 0.72 + 2.5

x = 3.22

The Analytic Hierarchy Process is being employed in a project selection decision. One major criteria, cost, receives a weighting
pshichka [43]

Answer:

Option "4" is the correct answer to the following situation.

Intermediate-term cost receives a weighting of 12%.

Explanation:

<u>GIVEN:</u>

Total cost receives weighting = 40%

  • short term cost weighting  = 50% of (Total cost receives weighting)

                                    = 50% of 40% = 20%

  • intermediate term cost weighting  

                                    = 30% of (Total cost receives weighting)

                                     = 30% of 40% = 12%

  • long term cost weighting

                                    = 20% of (Total cost receives weighting)

                                    = 20% of 40% = 8%

Therefore option "4" is the correct answer to the above situation.

The government should extend the duration of unemployment benefits to those workers who lost their jobs due to outsourcing. This
AlladinOne [14]

Answer:

Option D                      

Explanation:

A positive or explanatory statement in the humanities and psychology is about what "is," "was" or "will be," and does not involve any impression of acceptance or rejection.

The positive explanation is supported by empirical evidence. For eg, "A rise in taxes would lead to less usage" and "A decrease in fuel production would cause an increase to its value."

Positive assumptions are commonly used to explain the observable, such as the inflation rate in a country. These are primarily used to explain hypotheses and principles.
