Answer:
C. 60
Step-by-step explanation:
From triangle ADB,
![|AD|^2+|BD|^2=|AB|^2](https://tex.z-dn.net/?f=%7CAD%7C%5E2%2B%7CBD%7C%5E2%3D%7CAB%7C%5E2)
![|AD|^2+16^2=20^2](https://tex.z-dn.net/?f=%7CAD%7C%5E2%2B16%5E2%3D20%5E2)
![|AD|^2=20^2-16^2](https://tex.z-dn.net/?f=%7CAD%7C%5E2%3D20%5E2-16%5E2)
![|AD|^2=400-256](https://tex.z-dn.net/?f=%7CAD%7C%5E2%3D400-256)
![|AD|^2=144](https://tex.z-dn.net/?f=%7CAD%7C%5E2%3D144)
![|AD|=\sqrt{144}](https://tex.z-dn.net/?f=%7CAD%7C%3D%5Csqrt%7B144%7D)
![|AD|=12](https://tex.z-dn.net/?f=%7CAD%7C%3D12)
From triangle ADC,
![|CD|^2+12^2=15^2](https://tex.z-dn.net/?f=%7CCD%7C%5E2%2B12%5E2%3D15%5E2)
![|CD|^2+144=225](https://tex.z-dn.net/?f=%7CCD%7C%5E2%2B144%3D225)
![|CD|^2=225-144](https://tex.z-dn.net/?f=%7CCD%7C%5E2%3D225-144)
![|CD|^2=81](https://tex.z-dn.net/?f=%7CCD%7C%5E2%3D81)
![|CD|=9](https://tex.z-dn.net/?f=%7CCD%7C%3D9)
The perimeter is the distance around the figure.
The perimeter
![=15+20+16+9](https://tex.z-dn.net/?f=%3D15%2B20%2B16%2B9)
![=60](https://tex.z-dn.net/?f=%3D60)
the larger the sample the more accurate the prediction
so since Tim looked at a larger quantity of coins his would be more accurate
87.5 percent
Reason: 40/40-5/40 is 35/40. Divide 35/40 and you get 0.875. Multiply by a hundred and you get 87.5%
