Answer:
5% did not pass inspection
Step-by-step explanation:
Given
![Inspected= 340](https://tex.z-dn.net/?f=Inspected%3D%20340)
![Passed = 323](https://tex.z-dn.net/?f=Passed%20%3D%20323)
Required
Determine the percentage of parts that didn't pass inspection.
First, we need to calculate the number of those that didn't pass inspection.
![Failed = Inspected - Passed](https://tex.z-dn.net/?f=Failed%20%3D%20Inspected%20-%20Passed)
![Failed = 340 - 323](https://tex.z-dn.net/?f=Failed%20%3D%20340%20-%20323)
![Failed = 17](https://tex.z-dn.net/?f=Failed%20%3D%2017)
Next, we calculate the percentage as follows:
![\% = \frac{Failed}{Inspected} * 100\%](https://tex.z-dn.net/?f=%5C%25%20%3D%20%5Cfrac%7BFailed%7D%7BInspected%7D%20%2A%20100%5C%25)
The above formula is derived by dividing the number of parts that didn't pass inspection by the total machine inspected, then multiplied by 100%
So:
![\% = \frac{17}{340} * 100\%](https://tex.z-dn.net/?f=%5C%25%20%3D%20%5Cfrac%7B17%7D%7B340%7D%20%2A%20100%5C%25)
![\% = \frac{17 * 100\%}{340}](https://tex.z-dn.net/?f=%5C%25%20%3D%20%5Cfrac%7B17%20%2A%20100%5C%25%7D%7B340%7D)
![\% = \frac{1700\%}{340}](https://tex.z-dn.net/?f=%5C%25%20%3D%20%5Cfrac%7B1700%5C%25%7D%7B340%7D)
![\% = 5\%](https://tex.z-dn.net/?f=%5C%25%20%3D%205%5C%25)
<em>5% did not pass inspection</em>
