Answer:
probability = 0.008
probability = 0.0256
Explanation:
we know here probability of defective is 0.2
so probability of not defective is 1 - 0.2 = 0.8
as we know 3 item is arrive off process line in succession
so The probability that an item is defective is
as P(defective) = 0.20
as all item are independent so
probability that all three items are defective is
probability = 0.20 × 0.20 × 0.20 = 0.008
and
probability that exactly 3 of next 4 are defective
so number of way that can choose 3 out of 4 is
= 
= 4
so as all are independent probability is
probability = ( the number of way to choose 3 out of 4 ) × ( 3 item defective ) × ( 1 item not defective )
probability = 
× 0.2³ × ( 1- 0.2)
probability = 4 × 0.008 × 0.8
probability = 0.0256
Answer:
c) The investment is mutually exclusive with another investment under consideration.
Explanation:
The main indicator as to whether or not accept a project or not is the net present value (NPV). Only projects with a positive NPV should be considered. On the other hand, the internal rate of return (IRR) has a couple of issues and is not that reliable because it does not consider the size of the projects, or associated future costs, or even the duration of the projects. The IRR is not a good method to evaluate long term projects.
So when you have to compare mutually exclusive projects, the IRR should not be considered due to the issues previously mentioned.
Answer: b. All the answer options are potential problems.
Explanation:
In other to get a truly unbiased result from surveys, the sample chosen should be completely random. This method is not random as the people being chosen are selected which means that the basic underlying principle of probability sampling of randomness is violated.
The representativeness of the sample might also be affected if only a certain type of people look like they will answer which means that only they will be represented in the sample. These problems have a strong chance of influencing the research in a negative way as the research may be biased.
And of course the response rate will likely be lower as only a certain type of people are being looked for and they might not number much.
Answer: True
Explanation:
According to Peter Senge, he described team learning as a team skill which is required to be practiced by the team members that are involved so that they will all be able to develop their learning skills collectively.
Organizational learning works best when there is integrated thinking and acting at all levels of the organization.
Answer:
The correct answer is letter "D": Depreciation should not be recorded in years in which the market value of the asset has increased.
Explanation:
Depreciation indicates how much the value of the asset has been used. It also aims to match the cost of the asset to the income that the asset helps the company to earn. Used as an income tax deduction, the depreciation calculation provides businesses with an annual allowance for the use and deterioration of tangible assets such as machinery, equipment, and buildings.
<em>Depreciation is recorded throughout all the useful life of an asset until its disposal.</em>
