Step-by-step explanation:
Answer:
The probability that the wait time is greater than 14 minutes is 0.4786.
Step-by-step explanation:
The random variable <em>X</em> is defined as the waiting time to be seated at a restaurant during the evening.
The average waiting time is, <em>β</em> = 19 minutes.
The random variable <em>X</em> follows an Exponential distribution with parameter
.
The probability distribution function of <em>X</em> is:

Compute the value of the event (<em>X</em> > 14) as follows:

Thus, the probability that the wait time is greater than 14 minutes is 0.4786.

Step-by-step explanation:
V=4
3πr3=4
3·π·11.53≈6370.6263
Answer:
Step-by-step explanation:
X=2
Y=-7
Then if x is -6 u have to find what times 2 is -6 Which is -3.
so -7 x -3 is 21. Y is 21
