I think the equation is formed wrong, as there is no point in having x-4=x-2 twice.

It has no solution.

The sum of positive integers b and h is 34. If their difference is 8, what is the value of bh

kherson [118]

B + h = 34
b - h = 8 then b = h + 8

h + 8 + h = 34
2h + 8 = 34
2h = 34 - 8
2h = 26
h = 26/2
h = 13

b = h + 8
b = 13 + 8 = 21

Proof:
21 + 13 = 34
21 - 13 = 8

Value of bh = 21 * 8 = 168

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

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
