The table shows a simulation to predict how many cars will arrive at a car wash. Each event represents how many cars arrive duri
Svetradugi [14.3K]

Answer:

The number of cars passing or the people arriving during lunch hour will be around 220

Step-by-step explanation:

First we find the for ten minutes period from given data:

Average Cars in 10 minutes = (18+38+87+16+56+5)/6

Average Cars minutes = 36.67

Now, for average cars in 1 hr, we must multiply this value by 6. As, 10 minutes multiplied by 6 equals 1 hr.

Average cars in an hour = 36.67*6

<u>Average Cars in an hour = 220</u>

Hence, the number of cars or people arriving during lunch hour will also be equal to average number of cars arriving during an hour.
