It is given in the question that, the swimming pool had 2.5 million liters of water in it. Some water evaporated, and then the pool only had 2 million liters of water in it.
So amount of water evaporated is
![= 2.5 -2 = 0.5 million](https://tex.z-dn.net/?f=%20%3D%202.5%20-2%20%3D%200.5%20million%20)
And percentage of water evaporated is
![= \frac{0.5}{2.5} *100 = 20%](https://tex.z-dn.net/?f=%20%3D%20%5Cfrac%7B0.5%7D%7B2.5%7D%20%2A100%20%3D%2020%25%20)
Therefore 20% of water evaporated .
Assuming that these are 6-sided dice, We can roll a 6 and a 3, and 5 and a 2, or a 4 and a 1, in order to get a difference of 3.
1/6 chance for each side, 1/36 to roll any one of those combinations.
Multiply that chance by 3, for the 3 combinations we can roll to give us a difference of 3, and we get 3/36, or an 8.(3)% reoccurring chance.<span />
Answer:
f(g(x)) = ![\sqrt{8x-22}](https://tex.z-dn.net/?f=%5Csqrt%7B8x-22%7D)
Step-by-step explanation:
Substitute x = g(x) into f(x), that is
f(g(x))
= f(8x - 13)
= ![\sqrt{8x-13-9}](https://tex.z-dn.net/?f=%5Csqrt%7B8x-13-9%7D)
= ![\sqrt{8x-22}](https://tex.z-dn.net/?f=%5Csqrt%7B8x-22%7D)
