HELP!!!!

OverLord2011 [107]

Answer:

Step-by-step explanation:

You just need the distance formula here. It's very simple to follow:

$d=\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }$

which, for us, looks like this:

$d=\sqrt{(13-4)^2+(19-7)^2}$ and

$d=\sqrt{9^2+12^2}$ and

$d=\sqrt{81+144}$ and

$d=\sqrt{225}$ so

d = 15

The number of typing errors made by a typist has a Poisson distribution with an average of two errors per page. If more than two

wlad13 [49]

Answer: 0.6767

Step-by-step explanation:

Given : Mean = $\lambda=2$ errors per page

Let X be the number of errors in a particular page.

The formula to calculate the Poisson distribution is given by :_

$P(X=x)=\dfrac{e^{-\lambda}\lambda^x}{x!}$

Now, the probability that a randomly selected page does not need to be retyped is given by :-

$P(X\leq2)=P(0)+P(1)+P(2)\\\\=(\dfrac{e^{-2}2^0}{0!}+\dfrac{e^{-2}2^1}{1!}+\dfrac{e^{-2}2^2}{2!})\\\\=0.135335283237+0.270670566473+0.270670566473\\\\=0.676676416183\approx0.6767$

Hence, the required probability :- 0.6767
