Okay so first since there are 4 red marbles, 4 blue marbles, and 12 yellow marbles, you add them together so the whole total would be 20 marbles now. Since there are 4 marbles, the probability of her pulling it out would be 4/20. So now that she took 1 red marble away, we have 19 marbles left. So now that has been finished, she 1 more yellow marble away so now we have 12/19. Now that it's completed you multiply the two, and now you should have 12/95, divide 12/95 and you'll get 0.126315789 in other words rounded that too the nearest hundredth and you'll get 0.13
<u>Answer:</u>
The correct answer option is D. 81.
<u>Step-by-step explanation:</u>
We are given the following expression and we are to find the value of x:
![log _ 3 x = 4](https://tex.z-dn.net/?f=%20log%20_%203%20x%20%3D%204%20)
We can inverse
and re-write it as
.
Doing that, we will raise both the sides of the equation to the power of 3 to get:
![3 ^ { log 3 x } = 3 ^ 4](https://tex.z-dn.net/?f=%203%20%5E%20%7B%20log%203%20x%20%7D%20%3D%203%20%5E%204%20)
x = 81
The amount of the 12 grams sample of gold-195m having a half-life of 30.5 s that would remain after 41 s is 4.726 g
<h3>How to determine the number of half-lives </h3>
- Half-life (t½) = 30.5 s
- Time (t) = 41 s
- Number of half-lives (n) =?
n = t / t½
n = 41 / 30.5
n = 82/61
<h3>How to determine the amount remaining </h3>
- Original amount (N₀) = 12 g
- Number of half-lives (n) = 82/61
N = N₀ / 2ⁿ
N = 12 / 2^(82/61)
N = 4.726 g
