Suppose that the number of calls coming per minute into an airline reservation center follows a Poisson distribution. Assume tha

dusya [7]

Answer:

0.0497 is the required probability.

Step-by-step explanation:

We are given the following information in the question:

Mean number of calls = 3 calls per minute

The number of calls coming per minute is following a Poisson distribution.

Formula:

$P(X =k) = \displaystyle\frac{\lambda^k e^{-\lambda}}{k!}\\\\ \lambda \text{ is the mean of the distribution}$

We have to evaluate

$P( x =0) = \displaystyle\frac{\lambda^k e^{-\lambda}}{k!}\\\\P(x = 0) = \frac{3^0e^{-3}}{0!} = 0.0497$

0.0497 is the probability that no calls are received in a given one-minute period.

Show the steps<br> What is the slope of the 4x-y=6?

avanturin [10]

Answer:

the slope is 4

Step-by-step explanation:

-you have to solve for y;keep y by itself on one side of the equation

-you start by subtracting 4x on both sides(to get rid of it on the left side of the equation). you end up with -y= -4x+6

-y must be positive when it is alone, so to make it a positive, you have to divide both sides of the equation by -1. you end up with y= 4x-6

-so now that we have y by itself and positive, we can identify the slope. (the slope will always be what is right next to x, in this case it is 4). so the slope is 4

Is ( -1,5 ) a solution to the equation 2x+5y=0 Why or Why not?

icang [17]

Answer:

No, that is not a solution

Step-by-step explanation:

Plug in the numbers to their respective values, so -1 to x, and 5 to y.

2(-1) + 5(5) = 0

-2 + 25 = 0

23 = 0?

No, that is not a solution

A school flag consists of three rectangular sections that each have a different color.

Rasek [7]

Answer:

$Area =\frac{10x + 15}{2}$ in both cases

Step-by-step explanation:

See attachment for complete question.

From the attachment, we have the following given parameters

Green Section: Dimension: x by 2

Orange Section: Dimension: 2 by $1\frac{1}{2}$

Purple Section: Dimension: 3 by (x + $1\frac{1}{2}$ )

Solving (a): Area of the flag as a sum of each section

We simply calculate the area of each section.

$Area = Length * Width$

For the green section;

$Area = x * 2$

$Area = 2x$

For the orange section

$Area = 2 * 1\frac{1}{2}$

$Area = 3$

For the purple section

$Area = 3 * (x + 1\frac{1}{2})$

$Area = 3 * (x + \frac{3}{2})$

$Area = 3x + \frac{9}{2}$

Total Area = Sum of the above areas

$Area = 2x + 3 + 3x + \frac{9}{2}$

Collect Like Terms

$Area = 2x + 3x+ 3 + \frac{9}{2}\\$

$Area = 5x+ \frac{6+9}{2}$

$Area = 5x+ \frac{15}{2}$

$Area =\frac{10x + 15}{2}$

Solving (b): Area of the flag as a product

From the attachment,

$Length = 2 + 3$

$Length = 5$

$Width = x + 1\frac{1}{2}$

$Area = Length * Width$

$Area = 5(x + 1\frac{1}{2})$

$Area = 5(x + \frac{3}{2})$

$Area = 5x + \frac{15}{2}$

Take LCM

$Area = \frac{10x + 15}{2}$
