Steve manages a skate park and he has been analyzing the attendance data. Steve finds that the number of visitors increases expo
nentially as the temperature increases, and this situation is represented by the function f(x) = 5x. Steve also finds a linear equation that models the number of people who leave the park early depending on the change in temperature, and it is represented by f(x) = −x + 6. The graph of the two functions is below. Find the solution to the two functions and explain what the solution represents. (10 points)

Answer:
0.95 = 95% probability that the next person to purchase this car will request at least one of automatic transmission or built-in GPS
Step-by-step explanation:
We solve this question treating these probabilities as Venn sets.
I am going to say that:
Event A: Requesting automatic transmission
Event B: Requesting built-in GPS
90% of all buyers request automatic transmission
This means that
82% of all buyers request built-in GPS
This means that
77% of all buyers request both automatic transmission and built-in GPS.
This means that
What is the probability that the next person to purchase this car will request at least one of automatic transmission or built-in GPS
This is , which is given by:
So
0.95 = 95% probability that the next person to purchase this car will request at least one of automatic transmission or built-in GPS
