Answer:

w = 18; l = 62

Step-by-step explanation:

The formula for perimeter of a rectangle is P = 2l + 2w, where l represents length and w represents width

We know that the length can be found using the equation l = 3w + 8

Plugging this in for l in the original formula for perimeter gives us 160 = 2 * (3w + 8) + 2w

160 = 6w + 16 + 2w

160 = 8w + 16

144 = 8w

18 = w

Plugging 18 in for the second equation gives us 3 * 18 = 54 + 8 = 62 = l

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
