The disruption which is not a major cause of a high rate of species extinction on planet Earth is: c. earthquakes.
<h3>What is extinction?</h3>
Extinction refers to a situation in which a species, family, or other taxonomic group of living organisms such as animals or plants become extinguished, destroyed, or exterminated (dead).
This ultimately implies that, extinction literally means the extermination of a species, family, or other taxonomic group of living organisms. However, earthquakes are disruption which aren't a major cause of a high rate of species extinction on planet Earth.

Finding the new mean is simple: If ![E[X]=10](https://tex.z-dn.net/?f=E%5BX%5D%3D10)
, then ![E[2X]=2E[X]=20](https://tex.z-dn.net/?f=E%5B2X%5D%3D2E%5BX%5D%3D20)
.
Meanwhile, the standard deviation is the square root of the variance, which is given by
![V[X]=E[X^2]-E[X]^2\implies V[2X]=E[(2X)^2]-E[2X]^2=4E[X^2]-(2E[X])^2](https://tex.z-dn.net/?f=V%5BX%5D%3DE%5BX%5E2%5D-E%5BX%5D%5E2%5Cimplies%20V%5B2X%5D%3DE%5B%282X%29%5E2%5D-E%5B2X%5D%5E2%3D4E%5BX%5E2%5D-%282E%5BX%5D%29%5E2)
![\implies V[2X]=4\underbrace{\left(E[X^2]-E[X]^2\right)}_{V[X]}=12](https://tex.z-dn.net/?f=%5Cimplies%20V%5B2X%5D%3D4%5Cunderbrace%7B%5Cleft%28E%5BX%5E2%5D-E%5BX%5D%5E2%5Cright%29%7D_%7BV%5BX%5D%7D%3D12)
and so the new standard deviation would be ![\sqrt{V[2X]}=\sqrt{12}=2\sqrt3](https://tex.z-dn.net/?f=%5Csqrt%7BV%5B2X%5D%7D%3D%5Csqrt%7B12%7D%3D2%5Csqrt3)
.
First you get the variable alone.
then divide.
Answer:
there's no statement above so I cant really answer the question
Answer:
According Dr. Paul Atchley, texting, posting on social media or performing any other distracting activities while driving releases a small dopamine boost inside a human's brain.
Explanation:
Science describes why people text or perform any other distracting activities while driving. According Dr. Paul Atchley, texting, posting on social media or performing any other distracting activities while driving releases a small dopamine boost inside a human's brain. As a result, driver gets distracted.
Dopamine is a form of the feel-good neurotransmitter. This neurotransmitter give us feelings of pleasure and satisfaction.
