Answer:

This is useful to choose which calculation to perform.

Step-by-step explanation:

1) Firstly, let's consider that the Binomial Distribution tends to the Poisson Distribution given certain conditions:

n\rightarrow \infty, p\rightarrow 0, \lambda =np

Roughly, they tend to the same value.

2) The Binomial Probability is calculated through this formula:

Binomial: P(X=x)=\binom{n}{x}p^{x}(1-p)^{n-x}

Poisson Distribution this way:

Poisson:P(X=x)=\frac{\lambda^{x} e^{-\lambda }}{x!}

3) If we plug

p=\frac{\lambda }{n}

In the Binomial formula, given an "n" a very large quantity we'll have a closer outcome to Poisson.

P(X=x)=\binom{n}{x}\left ( \frac{\lambda }{n} \right )^{x}(1-\frac{\lambda }{n})^{n-x} \approx \frac{\lambda^{x} e^{-\lambda }}{x!}

4) This is useful especially due to the convenience of calculating.

Because operating with exponentials and factorials, is hard and sometimes 'n' and 'p' may also be unknown, and sometimes the known parameter is the Mean.

In the rectangle below AC has a length of 28. What is the length of ED? If necessary, round your answer to two decimals places.
expeople1 [14]
<span>The diagonals of a rectangle have equal lengths. Since AC has a length of 28, and AC is a diagonal, the other diagonal BD also has a length of 28. The diagonals of a rectangle also bisect each other. So diagonal BD is bisected by the other diagonal AC at point E. And since diagonal BD has a length of 28 then BE and ED both have a length which is of 28, or 14 each.

Answer: ED has a length of 14.</span>

professor190 [17]

Answer:

1/2

Step-by-step explanation:

Pick two points on the line

(2,0) and (4,1)

Use the slope formula

m= (y2-y1)/(x2-x1)

  = (1-0)/(4-2)

   = 1/2
