2. 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? (1 point)

	x 9.48 because |x ? 0.23| + 9.25 > 0
	x 9.48 because |x ? 9.25| > 0.23
	x 9.48 because |x ? 0.23| + 9.25 > 0
	x 9.48 because |x ? 9.25| > 0.23
