The rate at which customers are served at an airport check-in counter is a Poisson process with a rate of 8.1 per hour. The prob

just olya [345]

Answer:

Value of a is 0.667

Step-by-step explanation:

We are given the following in the question:

The rate of customer at an airport follows a Poisson distribution with

$\lambda = 8.1$

The normal approximation of Poisson distribution can be done in the following manner

$\mu = \lambda = 8.1\\\sigma^2 = \lambda = 8.1\\\sigma = \sqrt{8.1} = 2.85$

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

We have to find the value of a such that

$P(X_p > 50)=P(Z > a)$

More than 50 customers per 5 hours means more than 10 customer per hour.

Thus, we can write

$P( x > 10) = P( z > \displaystyle\frac{10 - 8.1}{2.85}) = P(z > 0.667)$

Therefore, value of a is 0.667

In the number 439 how is the value of three related to the value of nine

ratelena [41]

The 3 is in the tens place, meaning the value of the 3 is 3x10.

The 9 is in the ones place, meaning the value of the 9 is 9x1

So the place value of the 3 is ten times the value of the place value of the 9.
