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.
71n + 5600
I don't see which option is this though. I guess a)
Using the distance formula:
AB^2 = (-2-6)^2 = (2-2)^2
= 64
AB = 8 units
BC^2 = (6-0)^2 + (2-8)^2
= 36 + 36
= 72
BC = 6 root 2
AC^2 = (-2-0)^2 + (2-8)^2
= 4 + 36
= 40
AC = 2 root 10
Perimeter = 8 + 6 root 2 + 2 root 10
= 2 (4 + 3 root 2 + root 10) units
