user100 [1]

<u>Answer:</u>

x < 21.01 or x > 21.49 because |x - 21.25| > 0.24

<u>Step-by-step explanation:</u>

We know that each pack of almonds is targeted to weigh 21.25 oz.and a pack must weigh within 0.24 oz of the target weight to be accepted.

Assuming x to be the weight of a given pack of almonds, we can write it as:

|x-21.25| > 0.24

Now finding the range of rejected masses (x) of the almonds.

|x-a| >b

-b

|x-21.25| >0.24

-0.24>(x-21.25)>0.24

-0.24>x-21.25 or x-21.25>0.24

x or x>21.49

Therefore, the correct answer option is x < 21.01 or x > 21.49 because |x - 21.25| > 0.24.
