Such considerations include understanding of:
the reasons for and objectives of sampling.
the relationship between accuracy and precision.
the reliability of estimates with varying sample size.
the determination of safe sample sizes for surveys.
the variability of data.
Answer:
The thief has a 0.11% probability of hitting the pin code on the first try.
Explanation:
Simply, if the ATM card has a 3-digit code that can be repeated, and the board has 9 numbers (for example, from 1 to 9), we must start from the smallest number that could be formed with these numbers to the highest number that these numbers could also compose, which in the case would be 111 and 999. Then, 889 different numbers could be formed (it is the distance between 111 and 999), with which the possibility of hitting the key to the first attempt would be 1 in 889 times, or 1/889.
To take the probability to a percentage, we must know that 889 / 8.89 gives 100. Therefore, dividing 1 / 8.89 we will know the percentage of probabilities of hitting the key on the first attempt: 1 / 8.89 = 0.11.
This shows us that the thief has a 0.11% probability of hitting the key on the first try.
Answer:
Option A : Because at zero profit, with her revenue, she can cover all her costs—explicit and implicit (opportunity cost).
Explanation:
Perfectly Competitive Market
This is simply a market the market participants are said to be price takers that is no consumption decisions by individual consumers and no production decisions by individual producers can be able to affect the market price of a good.
Perfectly Competitive Industry
This is simply an industry where producers are said to be price takers.
Explicit Costs
These are costs that are simply known as "out-of-pocket" costs or in accounting costs. They are an individual's fixed and variable costs of doing business.
Implicit Costs
These are costs that do not partains to monetary payment as they are the opportunity costs of doing business.
It is said that at zero profit, the revenue covers all the costs, including the implicit ones. The fact that her implicit costs are covered shows that no outside option or opportunity that is superior to the zero economic profit option is chosened.
Answer:
Effect on income= $10,290 increase
Explanation:
Giving the following information:
Falcon can handle the special order, and for this order, a variable selling cost of <u>$2 per unit would be eliminated.</u>
<u>Because it is a special order that would not affect current sales, we won't take into consideration the fixed costs.</u>
<u></u>
<u>To calculate the effect on income, we need to use the following formula:</u>
Effect on income= Number of units sold*unitary contribution margin
Effect on income= 1,470*(21 - 14)
Effect on income= $10,290 increase
Answer:
$610,000
Explanation:
According to the midpoint value, we have to find out the mid value of two amount.
As in the question, the sales for 1996 and the sales for 1998 are given and we have to find out the sales for 1997
So, by using the mid point formula approach, the sales for 1997 is
= (1996 sales + 1998 sales) ÷ (Number of years)
= ($500,000 + $720,000) ÷ (2 years)
= ($1,220,000) ÷ (2 years)
= $610,000
Therefore, the estimated sales value of the company for year 1997 is $610,000
