A company did a quality check on all the packs of roasted almonds it manufactured. Each pack of roasted almonds is targeted to w

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.
