Question

A company did a quality check on all the packs of trail mixes it manufactured. Each pack of trail mixes is targeted to weigh 9.25 oz. A pack must weigh within 0.23 oz of the target weight to be accepted. What is the range of rejected masses, x, for the manufactured trail mixes?

x < 9.02 or x > 9.48 because |x - 0.23| + 9.25 > 0
x < 9.25 or x > 9.48 because |x - 9.25| > 0.23
x < 9.25 or x > 9.48 because |x - 0.23| + 9.25 > 0
x < 9.02 or x > 9.48 because |x - 9.25| > 0.23

Answer 2

for starters, we have to figure out our range. we start with the base 9.25:
the upper range is 9.25+0.23
the lower range is 9.25-0.23

Answer 3

let's draw a numberline to help visualize this
