In 4 hours they will be 400 miles apart 4 times 55 is 220 and 4 time 45 is 180 since there going in opposer directions add the miles together and it equals 400 so it takes 4 hours
I actually like math so I have no problem with it
Answer:
0.494 is the probability that on a selected day the stock price is between $186.26 and $192.47.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = $188.876
Standard Deviation, σ = $4.6412
We are given that the distribution of stock price is a bell shaped distribution that is a normal distribution.
Formula:
![z_{score} = \displaystyle\frac{x-\mu}{\sigma}](https://tex.z-dn.net/?f=z_%7Bscore%7D%20%3D%20%5Cdisplaystyle%5Cfrac%7Bx-%5Cmu%7D%7B%5Csigma%7D)
P(stock price is between $186.26 and $192.47)
![P(186.26 \leq x \leq 192.47) = 49.4\%](https://tex.z-dn.net/?f=P%28186.26%20%5Cleq%20x%20%5Cleq%20192.47%29%20%3D%2049.4%5C%25)
0.494 is the probability that on a selected day the stock price is between $186.26 and $192.47.
If the scale factor of the small pool to the large pool is equal to 0.12, the ratio of their volumes should be equal to 0.12^3 or equal to 1.728 x 10^-3. We multiply this value to the given volume of the large pool to get the volume of the small pool.
volume of small pool = (1.728 x 10^-3)(15,000 m^3)
volume of small pool = 25.92 m^3
Hence, the answer is the first choice.
