Answer:
sorry i was late but for anyone else who wants to know the answer is
D. Vygotsky's theory of cognitive development
Explanation:
I believe that the answer to the question provided above is
(1)<span> </span>Formulate the maxim
<span>(2) Generalize the maxim into a law of nature</span>
<span>(3) Figure out the perturbed social world (PSW), that is, what the world would be like if this law</span> of nature were added to existing laws of nature and things had a chance to reach equilibrium.<span> </span>
Hope my answer would be a great help for you. If you have more questions feel free to ask here at Brainly.
<span>they are known as phytoplankton.
If this was the appropriate answer make sure to mark as the brainliest!

CONGRATS!! i have some too
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)
.
