Answer:
Event is not unusual(p>0.05).
Step-by-step explanation:
Given that :

#The sample proportion is calculated as:

#Mathematically, the z-value is the value decreased by the mean then divided the standard deviation :

#We use the normal probability table to determine the corresponding probability;

Hence, the probaility is more than 0.05, thus the event not unusual and thus this is not necessarily evidence that the proportion of Americans who are afraid to fly has increased.
Answer:picture
Step-by-step explanation:
G(4) = 3x^2 - 3x - 9
Since the g(4) would be g(x) if you didn't know the number. So, substitute all of the x's for 4.
g(4) = 3(4)^2 - 3(4) - 9
g(4) = 3(16) - 12 - 9
g(4) = 48 - 3
g(4) = 45
