Answer:
B. Brook finished in 100 minutes, so Lamont was faster.
Step-by-step explanation:
1 hour = 60 Minutes
60 minutes + 40 minutes = 100 Minutes.
If you run and you have more minutes then someone else that means you ran for a longer time and your a little bit slower?

Answer:
Step-by-step explanation:
Given that that (X) the amount of time lapsed between consecutive trades on the New York Stock Exchange followed a normal distribution with a mean of 15 seconds.
i.e. X is normal with mean = 15 and unknown std deviation ![\sigma](https://tex.z-dn.net/?f=%5Csigma)
Given that![P(X](https://tex.z-dn.net/?f=P%28X%3C13%29%20%3D%207%25%20%3D%200.07)
i.e. P(![z](https://tex.z-dn.net/?f=z%3C%5Cfrac%7B13-15%7D%7B%5Csigma%7D%20%29%3D0.07)
z=-1.475 (from normal table)
Hence ![\frac{13-15}{\sigma}=-1.475\\\sigma = 1.356](https://tex.z-dn.net/?f=%5Cfrac%7B13-15%7D%7B%5Csigma%7D%3D-1.475%5C%5C%5Csigma%20%3D%201.356)
Using this we find P(X>17) = ![P(Z>\frac{17-15}{1.356} \\=P(Z>1.475)\\=0.5-0.428\\=0.072](https://tex.z-dn.net/?f=P%28Z%3E%5Cfrac%7B17-15%7D%7B1.356%7D%20%5C%5C%3DP%28Z%3E1.475%29%5C%5C%3D0.5-0.428%5C%5C%3D0.072)
The total amount payable for the car if you put a down 15% on a $9000 car and payment of $189.40 for 48 months will be:
Amount=(15/100×9000)+(189.40×48)
=1350+9091.2
=10,441.2
The total amount of money paid for the car after a period of time will be $10,441.2
