Answer:
Standard Error of the Mean = σ/√N =
Explanation:
SEM is calculated by taking the standard deviation and dividing it by the square root of the sample size.
Authoritarian
Explanation: An authoritarian ruler is basically a dictator, not allowing any freedom of choice. Authoritative provides some parental control, but probably with limits. Permissive is lenient.
The energy of an electromagnetic wave is typically emitted in short bursts referred to as photons.
<h3>What is electromagnetic energy?</h3>
Electromagnetic energy can be defined as form of energy that is primarily carried by electromagnetic waves such as:
This ultimately implies that, an electromagnetic energy refers to a form of energy that typically moves as particles at the speed of light, which is about three hundred million meters per seconds (3 × 10⁸ m/s).
In conclusion, we can infer and logically deduce that the energy of an electromagnetic wave is typically emitted in short bursts referred to as photons.

Answer:
Eliminate y by adding equations (1) and (3) because the coefficients on y are opposites. Then eliminate y by multiplying equation (1) by 2 and adding it to equation (2). Eliminate z by subtracting equations (1) and (2) because the coefficients are the same. Then eliminate z by multiplying equation (3) by 2 and adding it to equation (1).
