Answer:

A

Step-by-step explanation:

The constant of proportionality is the ratio between the two proportional variables in a directly proportional relationship. In this case, the variables are x and y.

To find the constant of proportionality, all we have to do is divide any value of y by its corresponding value of x. Let's take the values in the first row of the table. We know that x=2 and y=12, so the constant of proportionality is \frac{y}{x}=\frac{12}{2} =6. Hope this helps!

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.
