Tip, the teachers are lazy, they probably copied it from online search it up, and see if the answer key is there.
Answer:
The sigma capability of the process is 5.2857
Step-by-step explanation:
The sigma capability of a process is defined by the number of times that the distance between the lower specification limit and the upper specification limit contains the value of the standard deviation. In this case:
(USL - LSL) / sd = (247 - 265.5) / 3.5 = 5.2857
Then, the sigma capability of the process is 5.2857
Answer:
The number would have to be added is 2
Step-by-step explanation:
To find the form of the completing square of the quadratic function:
- Divide the coefficient of x by 2
- Subtract the numerical term from the square of the quotient
Let us do these steps with our question
∵ x² - 2x - 1 = 0
→ Divide the coefficient of x by 2
∵ The coefficient of x is -2
∴ -2 ÷ 2 = -1
→ Square the -1
∵ (-1)² = 1
→ Subtract the numerical term from 1
∵ The numerical term = -1
∵ 1 - (-1) = 1 + 1 = 2
∴ We must add 2 to -1 to get 1
→ (x² - 2x - 1 + 2) - 2 = 0
→ (x² - 2x + 1) = 2
→ (x - 1)² = 2
The number would have to be added is 2
Answer: A)32,708.3
formula is 2/3πr^3 so 2.09 times 15,625 = 32,656.25 which is the closest answer to A. 2.09 is 2/3 x pi which is 2/3π
