Answer:
490
Step-by-step explanation:
546-56= 490
490+56= 546
Answer:
I assume you meant 4x^2
So the answer in simplified form is -4x^2-11x+3
Answer:
•A c-chart is the appropriate control chart
• c' = 8.5
• Control limits, CL = 8.5
Lower control limits, LCL = 0
Upper control limits, UCL = 17.25
Step-by-step explanation:
A c chart is a quality control chart used for the number of flaws per unit.
Given:
Past inspection data:
Number of units= 100
Total flaws = 850
We now have:
c' = 850/100
= 8.5
Where CL = c' = 8.5
For control limits, we have:
CL = c'
UCL = c' + 3√c'
LCL = c' - 3√c'
The CL stands for the normal control limit, while the UCL and LCL are the upper and lower control limits respectively
Calculating the various control limits we have:
CL = c'
CL = 8.5
UCL = 8.5 + 3√8.5
= 17.25
LCL = 8.5 - 3√8.5
= -0.25
A negative LCL tend to be 0. Therefore,
LCL = 0

Answer:
133.04ft²
Step-by-step explanation:
Area of a circle is:
We are given the diameter. The radius of the given circle is 6. Note that the diameter is twice the radius.
Using 3.14 for pi:
The area is appropriately 133.04ft².
Hope this helps.
