Answer:
The predicted number of catfish in the pond is 57.
Step-by-step explanation:
We are given that the average number of catfish in the samples was 5.7. If the total population of fish in the pond is 200, the proportion of catfish in the pond will be 5.7/20 = x/200.
We have to calculate the predicted number of catfish in the pond.
The given proportion to us is;
![\frac{5.7}{20}=\frac{x}{200}](https://tex.z-dn.net/?f=%5Cfrac%7B5.7%7D%7B20%7D%3D%5Cfrac%7Bx%7D%7B200%7D)
Cross multiplying both the fractions we get;
![5.7 \times 200=x \times 20](https://tex.z-dn.net/?f=5.7%20%5Ctimes%20200%3Dx%20%5Ctimes%2020)
![\frac{57}{10} \times 200=x \times 20](https://tex.z-dn.net/?f=%5Cfrac%7B57%7D%7B10%7D%20%20%5Ctimes%20200%3Dx%20%5Ctimes%2020)
![{57} \times 20=x \times 20](https://tex.z-dn.net/?f=%7B57%7D%20%5Ctimes%2020%3Dx%20%5Ctimes%2020)
![x = \frac{57 \times 20}{20}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B57%20%5Ctimes%2020%7D%7B20%7D)
So, the predicted number of catfish in the pond is 57.
Answer:
<h2>BD = DC</h2>
Step-by-step explanation:
A perpendicular bisector is a line segment that goes form a vertex to its opposite side. The important characteristic is that a perpendicular bisector intersects the opposide at the mid point and with a right angle, that's why is called perpendicular and bisector.
So, Andrew can conclude that side BC is divide equally, that is, BD = DC.
Therefore, the right answer is the second choice.
