Answer: 11.5%
Explanation:Since 1 minute = 60 seconds, we multiply 12 minutes by 60 so that 12 minutes = 720 seconds. Thus, we're looking for a probability that the auditor will spend more than 720 seconds.
Now, we get the z-score for 720 seconds by the following formula:
where
So, the z-score of 720 seconds is given by:
Let
t = time for the auditor to finish his work
z = z-score of time t
Since the time is normally distributed, the probability for t > 720 is the same as the probability for z > 1.2. In terms of equation:
Hence, there is
11.5% chance that the auditor will spend more than 12 minutes in an invoice.

Answer:
The ordered triple does not satisfy the system of equations
Explanation:
The given ordered triple satisfy the given system of equations if the substitution x = 0, y = -4, and z = 0 satisfy the equations simultaneously. If anyone fails, then it does not satisfy
For the first equation:
This is satisfied
For the second equation:
This is also satisfied
For the third equation:
This is NOT satisfied
Therefore, the ordered triple does not satisfy the system of equations
Answer:
B) $1.25
Step-by-step explanation:
1. First, let's take two points. In this case, we're going to take (4,5) and (8,10). We took 2 points, so we can verify the unit rate/cost per pound of pineapple.
2. To find the cost per pound of pineapple, we have to divide the cost (the y-coordinates) by the pound (x-coordinates)
- 5 ÷ 4 = 1.25
- 10 ÷ 8 = 1.25
3. Now, since we can verify with 2 coordinates that the cost per pound is $1.25, the answer is B) $1.25.
