Answer:
Process Capability ratio / Index = 0.133
Step-by-step explanation:
From the question, we are told:
Upper limit of 9.16 ounces
Lower limit of 9.12 ounces
Process width of 0.05 ounces.
what is the process capability ratio
Process Capability ratio or Index formula
= Cp = (USL - LSL)/(6 × Standard deviation)
Cp = 9.16 - 9.12/6 × 0.05
Cp = 0.04/0.3
Cp = 0.13333333333
Approximately = 0.133
For the first problem, when you see expression like that it just means to write it twice, then FOIL it.
(2x-6) (2x-6)
If you don't know what FOIL is let me know and I can further explain it!
This also applies for the second question!
Answer:
14.5 ≥ g(1.5)
g = The number of trips to the grocery store.
You will have 11.5 gallons left.
