What is the slope of the line that passes through the points (-4, -9) and (5, 3)
egoroff_w [7]

Answer:

4/3

Step-by-step explanation:

Moving from (-4, -9) to (5, 3), x (the 'run') increases by 9 from -4 to 5, and y (the 'rise') increases by 12 from -9 to +3.  Thus, the slope of the line connecting the two points is

m = rise / run = 12/9 = 4/3

It may help to think of the change in x (9) as the horizontal leg of a right triangle and the change in y (12) as the vertical leg.  Then  

m = (vertical leg length) / (horizontal leg length) = 12/9 = 4/3

Suppose that telephone calls arriving at a switchboard follow a Poisson process with an average of 5 calls per minute. What is t
postnew [5]

Answer:

The correct answer is "0.0842".

Step-by-step explanation:

Given:

X = 5

By using the Poisson's distribution formula, we get

The probability will be:

⇒ P(x=2)=\frac{\lambda^x.e^{-\lambda}}{x!}

By substituting values, we get

                   =\frac{(5)^2\times e^{-5}}{2!}

                   =\frac{25\times e^{-5}}{2!}

                   =0.0842
