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:
The Capability Index for this process is 1.04. The right answer is B
Explanation:
According to the given data we have the following:
μ = 31 Seconds
USL = 45
LSL = 10
Standard deviation σ= 4.5
Therefore, in order to calculate the Capability Index for this process we would have to use the following formula:
Cpk=Min<u>(
USL-μ</u> , <u>μ-
LSL</u>)
3×σ 3×σ
Cpk=Min<u>(
45-31</u> , 31<u>-
10</u>)
3×4.5 3×4.5
Cpk = Min ( 1.04,1.56) = 1.04
The Capability Index for this process is 1.04
Answer:
C. 25.5%
Explanation:
Net operating cashflow = (250,000 - 100,000) = 150,000; This is a recurring cashflow; the PMT
Cost of equipment; the PV = 400,000
Next, calculate the rate of return using Net operating cashflow per year and the equipment cost. You can do this with a financial calculator;
N =5
PMT = 150,000
FV = 0
PV = -400,000
then CPT I/Y = 25.41%
Therefore the return is closest to 25.5%
Answer: <em>True</em>
Explanation:
The following statement is true, i.e. In accordance to the equity theory, she will try to change the working habits. The equity theory mostly concentrates on evaluating whether the allocation of commodities and resources is impartial to both of the relational partners. Here, equity is evaluated by contrasting the ratio in between the costs and rewards for each individual.

<h3>What is opportunity cost?</h3>
Opportunity cost of the next best option forgone when one alternative is chosen over other alternatives. When the family chooses to go for the restaurant meal, they forgo the opportunity for a home meal.
Opportunity cost = 30 / 10 = 3
