Answer: The microbes only grew in the bottles containing earth-like air.
Explanation:
The growth of microbe depends upon the availability of substrate, moisture, and gas. The atmosphere is a mixture of gases. Earth-like atmosphere favors the survival of many micro-organisms. Carbon dioxide, oxygen, methane, nitrogen, and others are valuable earth like gases that will favor the survival of many microorganisms. So, according to the given situation in the experiment microbes will grow in earth like air.
Im not 100% sure, but i believe it's crop production will increase.
Finding the new mean is simple: If
, then
.
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
.
Since Jupiter<span> is a gas planet, it </span>does<span> not </span>rotate<span> like a normal solid planet would. So the statement is true, Jupiter rotates more rapidly on its axis than Earth.</span>
