Answer:
DPMO = 40
Does not meet Six Sigma goals
Step-by-step explanation:
If there are 40 possible defects in each of the 5,000 devices, the number of defect opportunities is:

If 8 total defects were found, the DPMO for the sample is:

Six Sigma aims to reduce defects to 3.4 Defects Per Million Opportunities, since the DPMO is higher than 3.4, the process does not meet Six Sigma goals.
Answer:
a 1 = 10
a 2 = 10 * 1/5 = 2
a 3 = 2 * 1/5 = 2/5
a 4 = 2/5 * 1/5 = 2/25
a 5 = 2/25 * 1/5 = 2/125
S 5 = a 1 + a 2 + a 3 +a 4 + a 5= 10 + 2 + 2/5 + 2/25 + 2/125 =
= 1250/125 + 250/125 + 50/125 + 10/125 + 2/125 = <u> 1562 / 125</u>
The equation is saying x minus 7 is greater than -6, so treat the inequality symbol just how you would with a normal =. So x-7=-6, you need to find x, so to find x you need to keep x alone. So you get rid of the -7, so to do that since it is a negative you add 7 to -6, so that would mean that x=1. Now you put the inequality symbol back. So now it's x>1. This is the solution, x is greater than 1, or x>1. Hope this helps
