Number 8 is $1.29 number 6 is $47.31
Answer: P(X<6) = 0.3085 or 30.85%
Step-by-step explanation: Determine, first, z-score:
![z = \frac{x-\mu}{\sigma}](https://tex.z-dn.net/?f=z%20%3D%20%5Cfrac%7Bx-%5Cmu%7D%7B%5Csigma%7D)
x is a random variable for time a student takes to find a spot, in this case, x=6:
![z = \frac{6-6.5}{1}](https://tex.z-dn.net/?f=z%20%3D%20%5Cfrac%7B6-6.5%7D%7B1%7D)
z = -0.5
Using z-score table, find z-score:
P(X<6) = P(z< -0.5)
P(X<6) = 0.3085
<u>Probability of finding a parking spot in less than 6 minutes is approximately 30.85%.</u>
The average American eats 68 quarts of popcorn each year.
68*5= 340.
340*6= 2,040 quarts of popcorn.
Hopefully this helps! :)
