Answer:
Average range(R-bar) = Sum of the sample range for each sample/number of samples = (9+8+1+8+7) /5 = 33/5 = 6.6
Sample size = 8
For a sample size of 8 the factors for control limit for range (D3) = 0.136 (obtained from table of constraints for x-bar and R chart
LCL = R-bar × D3 = 6.6 × 0.136 = 0.90
Step-by-step explanation:
Answer:
66
Step-by-step explanation:
multiply everything together
Answer:
4
Step-by-step explanation:
We have been given that it equals 19 when added to 3 and multiplied by 4 so follow these steps:
1. set the equation 4x+3=19
2. solve for x
4x+3-3=19-3
This is used to solve for x
3. 4x=16 is found
4. if 4x=16, we divide 16/4 and get 4!
That's your answer hope it helped!
