Answer:
The y intercept is 80 and the line of the best fit is -3/5
Step-by-step explanation:
Answer: The radius of a sphere is 6 units
Step-by-step explanation:
Solution: We are given:
![\mu=600, \sigma =120](https://tex.z-dn.net/?f=%5Cmu%3D600%2C%20%5Csigma%20%3D120)
We need to find the z value corresponding to probability 0.84, in order to find the how much money almost 84% of gamblers spent at casino.
Using the standard normal table, we have:
![z(0.85) = 0.9945](https://tex.z-dn.net/?f=z%280.85%29%20%3D%200.9945)
Now we will use the z score formula to find the required amount:
![z=\frac{x-\mu}{\sigma}](https://tex.z-dn.net/?f=z%3D%5Cfrac%7Bx-%5Cmu%7D%7B%5Csigma%7D)
![0.9945=\frac{x-600}{120}](https://tex.z-dn.net/?f=0.9945%3D%5Cfrac%7Bx-600%7D%7B120%7D)
![0.9945 \times 120 = x - 600](https://tex.z-dn.net/?f=0.9945%20%5Ctimes%20120%20%3D%20x%20-%20600)
![119.34 = x - 600](https://tex.z-dn.net/?f=119.34%20%3D%20x%20-%20600)
![x = 719.34](https://tex.z-dn.net/?f=x%20%3D%20719.34)
approximately
Therefore, almost 84% of gamblers spent more than $720 amount of money at this casino.
