Use the image to determine the volume of the rock.

initial volume:

final volume:

volume of rock:

Initial Volume: 20 mL

Final Volume: 32  mL

Volume of the rock: 12mL

Step-by-step explanation:

From the image we see that the initial volume of water is 20 mL, and after the rock is put into the flask, the final volume is 32 mL. From this we conclude that the volume of the rock must be 32mL-20mL = 12 mL.

Thus we have:

Initial Volume: 20 mL

Final Volume: 32  mL

Volume of the rock: 12mL.

not enough information

step-by-step explanation:

we cannot know this, because the other students could have handed out 10 flyers, or they could have handed out 100. one way, the mean would go up, and another way, the mean would go down.
