Answer:
Step-by-step explanation:
area of triangle=1/2×8×3=12 cm²
volume=12×13=156 cm³
Using proportions, it is found that the best estimate for the raccoon population is of 930.
<h3>Proportions:</h3>
- This question is solved by <em>proportions</em>, using a rule of three.
- Out of 620 raccoons, 38 had tags. How many raccoons are there if the scientist tagged 57?
The <em>rule of three is:</em>
620 raccoons - 38 tagged
x raccoons - 57 tagged
Applying cross multiplication:
![38x = 620(57)](https://tex.z-dn.net/?f=38x%20%3D%20620%2857%29)
![x = \frac{620(57)}{38}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B620%2857%29%7D%7B38%7D)
![x = 930](https://tex.z-dn.net/?f=x%20%3D%20930)
The best estimate for the raccoon population is of 930.
