Answer: Both the mean and median decreased.
Step-by-step explanation:
The addition of the 500 lb baby elephant will have a huge impact on the mean, since you'll be finding the average (adding all numbers then dividing). So the only logical answer would be the chosen. The median will most likely either decrease or stay the same, but since staying the same isn't an option for the median, it's most likely going to be decrease.

Answer:
390 inches long
Step-by-step explanation:
The string = x
![\frac{x}{30} = 13](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B30%7D%20%3D%2013)
![30 (\frac{x}{30} ) = 30(13)](https://tex.z-dn.net/?f=30%20%28%5Cfrac%7Bx%7D%7B30%7D%20%29%20%3D%2030%2813%29)
x = 390 inches
Well, to find the perimeter we have to add all of the side lengths, so let's do that:
2x+3 +2x+3 +2x
And we know that this equals 36 so let's solve for x
2x+3+2x+3+2x = 36
6x+6 = 36
6x = 30
x = 5
So we know know that x = 5.
Now all you have to do is plug in the values of x into the lengths
2(5) + 3
= 10+3
= 13 is the length of two of the sides.
2x
= 2(5)
= 10
And 10 is the length of the last side.
10 divided by 5 equals 2
9 divided by 3 equals 3
