How are cumulative frequencies and percentiles different? How are they the same?

Answer #1

How
are cumulative frequencies and percentiles different? How are they
the same?

Two tuning forks that have the same amplitude but slightly
different frequencies are stuck at the same time to produce a
complex wave. What is this called? If the period of the complex
wave that they produce is 0.25s and the period of one of the tuning
fork is 0.04s. What is one possible frequency of the other tuning
fork? When the sinusoidal waves from the tuning fork are opposite
phases, what happens at those points to the complex wave...
