Answer: mean:4 Median: 3 mode:10
Step-by-step explanation:
I got the answer to be 0.9. To get the mean, you add up all the data and then divide it by the number of numbers in you data, so I did 0.5+0.7+1.0+1.7+0.6+1.0=0.8 and then divided by 7, giving me 0.9.
Hi :)
This kind of question is purely based upon proportionality. We are going to be using the cross product method to assess it.
First-hand, it can always help to write down the information that you do have, and the one that is missing.
Here;
450-pound tiger — > 15 pounds of meat
360-pound tiger — > ?? pounds of meat
The calculation you’ll want to use is the following:
360 x 15 / 450
The answer is 12 pounds.
Therefore, you would expect a 360-pound tiger to eat 12 pounds of meat per day.
I hope this helps! Have a nice day :)
