Answer: 99.7%
Step-by-step explanation:
A control chart is used in the identification of the assigned causes of variation for a process. The control limits are refered to as the horizontal lines that are below and above the center line which are used in judging whether a particular process is out of control.
In this case, the control limits, which is calculated as three standard deviations from the sample mean, simply means that about 99.7% of the sample points will be expected to fall between upper and lower control limits.

Answer: it’s the last one
Step-by-step explanation:
Answer:
Step-by-step explanation:
8/12=22/(12+6x-3)
8/12=22/(6x+9)
48x+72=264
48x=192
x=4
Let x be the contaminated water and y be the pure water. The system of equations would be
0.75x + 1y = 0.97
x + y = 1
75% = 0.75; 100% = 1.0; and 97% = 0.97
The two waters together made 1 gallon of drinkable water.
