Step-by-step explanation:
La frecuencia de una onda se define como el número de ciclos completos que realiza una partícula en un segundo.
f = n / t = 15 ciclos / 3 segundos = 5 ciclos por segundo o Hertz
El período de una onda es el tiempo que tarda la onda en realizar una oscilación o ciclo completo.
T = t / n = 3/15 = 0,2 segundos
Answer:
The Standard Deviation is a measure of how spread out numbers are.
Its symbol is σ (the greek letter sigma)
The formula is easy: it is the square root of the Variance. So now you ask, "What is the Variance?"
Variance
The Variance is defined as:
The average of the squared differences from the Mean.
To calculate the variance follow these steps:
Work out the Mean (the simple average of the numbers)
Then for each number: subtract the Mean and square the result (the squared difference).
Then work out the average of those squared differences. (Why Square?)
