PSYCHO15rus [73]

Answer:

the number of adult ticket sold is 107 tickets

Step-by-step explanation:

The computation of the number of adult ticket sold is shown below:

Let us assume the number of tickets be x,

So, the adult be x

And for student it would be 3x

Students= 2x

Adults= x

Total = 4x

Now the equation could be

4x = 428

x = 107

This x signifies the adult tickets sold i.e 107

Hence, the number of adult ticket sold is 107 tickets

An analyst in Bank of America, Santa Clara University Branch, believes that on Mondays customers arrive at the bank with rate 50
Aleksandr-060686 [28]

Answer:

0.0821

Step-by-step explanation:

If the arrival rate is 50 customers per hour (60 minutes), then the expected number of customers in 3 minutes is:

\lambda=\frac{50}{60}*3\\ \lambda=2.5\ customers/3\ minutes

Assuming a Poisson distribution with 2.5 customers per 3 minutes, the probability that zero customers arrive for 3 minutes is:

P(x=k)=\frac{\lambda^k*e^{-\lambda}}{k!}\\P(x=0)=\frac{2.5^0*e^{-2.5}}{0!}\\ P(x=0)=0.0821

The probability that the bank stays empty for three minutes is 0.0821.
