Answer: The probability that none of the calls would result in a reservation would be 0.72%.
Since there is an 18% chance that there would be a reservation, then there is a 72% chance that there is not a reservation.
Our goal is to determine the likelihood that there are no calls. Or that the 72% chance event happens 15 times.
We can use the following expression to find that repeated probability.
(0.72)^15 = 0.0072 or 0.72%
AC = 75 x 2 = 150 degrees
Answer:
C=401.92
Step-by-step explanation:
the equation for area of a circle is A=r^2 pi so if the area of this circle is A=64^2 pi, then we can see that 64 is the radius of the circle.
(A=r^2 pi
A=64^2 pi so r=64)
So if the radius is 64, then the diameter is (because diameter is double the radius) Then we use the newfound diameter and plug into the equation for Circumference of a circle which is
C=d pi
C=128 (3.14)
so C=401.92
Hope this helps! :)
You need 19 because the median would be the middle of 17 and 19 which would be 18
