Answer: D. marginal product; increasing; average variable cost; decreasing
Explanation:
The Marginal product curve is hump-shaped and the marginal cost curve is U-shaped because these two move in opposite directions to each other.
If the marginal cost is decreasing therefore, the marginal product must be increasing. If the marginal cost is decreasing and the marginal product is increasing, average variable cost will have to fall because every additional unit produced incurs less cost so the average has to fall as well.
Answer:
Let's assume that "X" be the number of employees in 2000.
∵ it's given :
From 2000 to 2003: the number of employees increased by a factor of 1/4
From 2003 to 2006: the number of employees decreased by a factor of 1/3
∴ We can equate the following details:
X×(increase in employee)×(decrease in employee) = 100
X×(
)×(
) = 100
X×(
)×(
) = 100
X×(
) = 100
X = 100×(
)
<em>X = 120 </em>
<u><em>Therefore, the correct option is (b)</em></u>
Answer: . two-stage area
Explanation:
In two-stage specimen sampling, a simple random sample of specimen is selected and then a simple random sample is selected from the units in each sampled specimen. Two-stage sampling is used when the sizes of the specimens are large, making it difficult or expensive to observe all the units inside them.
Answer:
A, independence
Explanation:
Motivation can be defined as the stimulation of individuals to achieve a certain goal.
It can also be said to be the a force that drives the wants, needs, etc of an individual. Motivation have various influencing factors as well as several modes.
Factors that influences motivation include; valence, instrumentality, expectancy, etc.
Modes of motivation include; intrinsic, extrinsic, introjected and identified motivation.
From the above question, independence isn't a factor that influences motivation. This is because independence, according to the dictionary, can be said to be a state of freedom from something.
Freedom does not motivate a person to achieve anything as there will be no pressure or driving force or even an individual to encourage. This makes goals impossible to difficult to achieve.
Cheers.
