a manufacturer of bicycle parts requires that a bicycle chain have a width of 0.3 inch with an absolute deviation of at most 0.0
quester [9]

Answer:

|w-0.3| \leq 0.0003

And solving we got:

-0.0003 \leq w-0.3 \leq 0.0003

0.3-0.0003 \leq w \leq 0.3+0.0003

0.2997 \leq w \leq 0.3003

Step-by-step explanation:

For this case we can define the following notation:

W represent the width

And we want a maximum error of 0.0003 so we can set up the following equation:

|w-0.3| \leq 0.0003

And solving we got:

-0.0003 \leq w-0.3 \leq 0.0003

0.3-0.0003 \leq w \leq 0.3+0.0003

0.2997 \leq w \leq 0.3003
