Julius is studying populations of robins in the local area. He counts 12

1 answer:

8 0

Well, he recaptured 3 out of the 7 he marked. We can presume that the other 5 are gone. The population would be 8 robins, because 4 of the robins Julius marked were not recaptured. Therefore, the population is around 8-10 robins.

notsponge [240]

Answer:

Image attached

Step-by-step explanation:

The question asks to represent the position of two animals in a the cartesian coordinates plane. This is two perpendicular axis, the y-axis is the vertical one and the x-axis is the horizontal one. The animals are represented by dots, called a for the seagull and b for the shark.

Since the y-axis is the vertical axis and they ask to draw the points with a verical difference between them, we will draw the points in it.

Say the x-axis represents the sea surfice. The seagull would be over the sea, and the shark under the sea surfice (under x-axis).

This is the resulting drawing
