1/4 and 3/12 are equal to 6/24

divide 6 and 24 by 6 to get 1/4 and divide 6 and 24 by 2 to get 3/12

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

Distance between (-4, 6) and (3, 7)

sweet-ann [11.9K]

Answer: $5\sqrt{2}$

Step-by-step explanation:

$Distance\ formula=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} }$

plugging in the values we know:

$x_2 = 3,\ x_1=-4,\ y_2=7,\ y_1=6$

Therefore,

$Distance=\sqrt{(3-(-4))^2+(7-6)^2}$

$\rightarrow\ \sqrt{(3+4)^2+(1)^2}$

$\rightarrow\ \sqrt{7^2+1}$

$\rightarrow\ \sqrt{50}$

$\rightarrow\ \sqrt{5\times5\times2}$

$\rightarrow\ \large\boxed{5\sqrt{2}}$
