Answer: weight of elephant has smaller percent error.
Step-by-step explanation:
Percent error = ![\dfrac{|\text{estimated value -actual value}|}{\text{actual value}}]\times100](https://tex.z-dn.net/?f=%5Cdfrac%7B%7C%5Ctext%7Bestimated%20value%20-actual%20value%7D%7C%7D%7B%5Ctext%7Bactual%20value%7D%7D%5D%5Ctimes100)
Estimated weight of elephant = 10,000 pounds
Actual weight of elephant = 12,400 pounds
Percent error of weight = ![\dfrac{|12400-10000|}{12400}\times100\%\approx19.35\%](https://tex.z-dn.net/?f=%5Cdfrac%7B%7C12400-10000%7C%7D%7B12400%7D%5Ctimes100%5C%25%5Capprox19.35%5C%25)
Estimated weight of hippopotamus = 2,500 pounds
Actual weight of hippopotamus = 3,600 pounds
Percent error of weight = ![\dfrac{|2500-3600|}{3600}\times100\%\approx30.55\%](https://tex.z-dn.net/?f=%5Cdfrac%7B%7C2500-3600%7C%7D%7B3600%7D%5Ctimes100%5C%25%5Capprox30.55%5C%25)
Since 19.35 < 30.55
hence, weight of elephant has smaller percent error.
