<h3><u>
Answer:</u></h3>
Hence, the actual range weight's of the object is:
144.9 lbs -145.5 lbs.
<h3><u>
Step-by-step explanation:</u></h3>
It is given that:
Weight of an object on particular scale is 145.2 lbs.
Measurement may vary the actual weight by at most 0.3 lbs.
i.e. the weight may increase or decrease the actual weight by 0.3 lbs.
Hence, the least weight that will be obtained by the object if the weight may vary by 0.3 lbs is:
145.2-0.3=144.9 lbs.
Hence, the greatest weight that will be obtained by the object if the weight may vary by 0.3 lbs is:
145.2+0.3=145.5 lbs.
Hence, the actual range weight's of the object is:
144.9 lbs -145.5 lbs.
