Answer:
Explained below.
Step-by-step explanation:
A) We are not given a population percentage of people who wear dark or light clothes. For example, the number of people wearing dark cloths were maybe 700 and only 100 were killed.
So using the percentage of those killed to draw a conclusion is not a true representation of the reality. Thus, it is not justified to conclude that it is safer to wear light-colored clothing at night.
B) The additional information needed will be the population percentage of all pedestrians both those killed and those not killed who wore light-colored and dark colored clothing at night.
Answer:
Practical domain: ![v\in[0,230]\ or\ 0\leqslant v\leqslant 230](https://tex.z-dn.net/?f=v%5Cin%5B0%2C230%5D%5C%20or%5C%200%5Cleqslant%20v%5Cleqslant%20230)
Roger can earn $510 at most.
Step-by-step explanation:
We are given the function
![E(v)=50+2v](https://tex.z-dn.net/?f=E%28v%29%3D50%2B2v)
Which gives the earnings of Roger when he sells v videos. Since the play’s audience consists of 230 people and each one buys no more than one video, v can take values from 0 to 230, i.e.
![v\in[0,230]\ or\ 0\leqslant v\leqslant 230](https://tex.z-dn.net/?f=v%5Cin%5B0%2C230%5D%5C%20or%5C%200%5Cleqslant%20v%5Cleqslant%20230)
That is the practical domain of E(v)
If Roger is in bad luck and nobody is willing to purchase a video, v=0
If Roger is in a perfectly lucky night and every person from the audience wants to purchase a video, then v=230. It's the practical upper limit since each person can only purchase 1 video
In the above-mentioned case, where v=230, then
![E(230)=50+2(230)=50+460=510](https://tex.z-dn.net/?f=E%28230%29%3D50%2B2%28230%29%3D50%2B460%3D510)
Roger can earn $510 at most.
