1) A company makes boxes of crackers that should weigh 213g. A
quality-control inspector randomly selects boxes to weigh. Any box
that varies from the weight by more than 5g is sent back. What is the
range of allowable weights for a box of crackers?​

Respuesta :

The boxes can weight at most 5 grams less than the desired amount, so they can't be lighter than

[tex]213-5=208[/tex] grams

Similary, they can't weight more than 5 grams more than the desired amount, so they can't be heavier than

[tex]213+5=218[/tex] grams

So, the acceptable range is between 208 and 218.
