Answer:
Median= 14
Mean= 90
Step-by-step explanation:
Median:
Put the numbers in order,
4, 7, 9, 14, 16, 19, 20 Then after that you find the number exactly in the middle. That number ends up to be 14.
Mean:
Add up all of the numbers and then round it to the nearest tenth: 90
Median= 14
Mean= 90

9514 1404 393
Answer:
216 J
Step-by-step explanation:
The kinetic energy is given by ...
KE = 1/2mv^2
KE = (1/2)(3 kg)(12 m/s)^2 = 216 kg·m²/s² = 216 J
The kinetic energy of the toy is 216 joules.
__
Its potential energy depends on its height.
A best estimate would be 209
