Answer: D. determine the root cause of the problem. provide meaningful work for quality inspectors.

Explanation:

The control chart is a graph used to study how a process changes over time. Data are plotted in time order. A control chart always has a central line for the average, an upper line for the upper control limit, and a lower line for the lower control limit. These lines are determined from historical data.

Allow operators to control the process. Improve process control to give less variation in the output, lower the unit cost, and increase the processing capacity. Provide a common language for all staff to discuss and improve processes. Control charts are not a substitute for action.

I don't quite understand the LCD and the unlike denominators properly. May someone explain it, please.
Whitepunk [10]

Hey!

----------------------------------------------------------------------

LCD stands for Lowest Common Denominator.

----------------------------------------------------------------------

Explanation:

So let's say we have the equation 1/9 * 16/27

We want to find the LCD of both fractions. To find the LCD of both fractions find a the lowest common denominator in both fractions.

In this equation the lowest common denominator is 27 because 9 can go in 27 and 27 can go into itself. Se basically 27 is the lowest possibly common denominator both fractions can get to.
