Answer:
Low Frequency, Long Wavelength, and Low Energy Transfer
Explanation:
Radio waves are on the larger(and lower frequency) side of the electromagnetic spectrum. These longer wavelengths mean that radio waves have a lower frequency because it takes longer for larger waves to travel. Therefore, less radio waves can travel a certain distance in a minute than a wave of a shorter wavelenght(and therefore lower frequency). Radio waves are considered a low-energy transfer wave. This is because they can be used in most environments for communication, air-traffic control, and broadcasting with little to no harm to the organisms around them. Even though radio waves can be found all around us, because they don't carry much energy, we aren't harmed by the radio waves.
Answer:
b. The number of digits in a randomly selected row until a 3 is found.
Explanation:
A random variable often used in statistics and probability, is a variable that has its possible values as numerical outcomes of a random experiment or phenomenon. It is usually denoted by a capital letter, such as X.
In statistics and probability, random variables are either continuous or discrete.
1. A continuous random variable is a variable that has its possible values as an infinite value, meaning it cannot be counted.
2. A discrete random variable is a variable that has its possible values as a finite value, meaning it can be counted.
Also, any random variable that meets certain conditions defined in a research study.
Hence, an example of a geometric random variables is the number of digits in a randomly selected row until a 3 is found.
