when you toss a coin three times, the total number of possible outcomes is
There were three times as many tall plants as short plants.
Three times as many shorts plants as tall plants.
Conducting an experiment three times helps to improve the reliability of the results by reducing the impact of random variability. It allows for averaging out any inconsistencies and provides a better estimate of the true outcome. Additionally, repeating the experiment helps to identify any errors or inconsistencies that may have occurred during the initial trial.
The third harmonic is a frequency that is three times the fundamental frequency of a wave or signal. It is a multiple of the fundamental frequency and is characterized by having three times the wavelength and three times the frequency of the original wave.
It means having a value that is three times as large.
Trials are the amount of times a certain experiment is repeated.
