Answer:
The range can be expressed as: [tex]30.485\leq x\leq 30.515[/tex]
which agrees with answer D
Step-by-step explanation:
If the tolerance is 0.015 cm for the final rod, then the range of acceptable lengths for the rod is between 30.5 - 0.05 and 30.5 + 0.015 . That is between
30.485 cm and 30.515 cm
Which can be expressed as: [tex]30.485\leq x\leq 30.515[/tex]
