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

Tanzania [10]

Answer:

A frequency distribution lists the number of occurrences of each category of data, while a relative frequency distribution lists the proportion of occurrences of each category of data.

Explanation:

A "frequency distribution" is one of the ways in organizing a data, either by listing the information, putting them in a table or showing them in a graph. The items in the list (distinct values) are then counted when it comes to the number of times they've occurred.

Thus, this explains the first answer, "number."

On the other hand, a "relative frequency distribution" refers to the proportion of the overall number of observations in a particular category. You can get this by dividing each frequency with the total number of data in a sample.

Thus, this explains the second answer, "proportion."

(-155)^4/19^2 : (155/19)^3

Snezhnost [94]

Answer:

$\frac{ { - 155}^{4} }{ {19}^{2} } \div { (\frac{155}{19} }) ^{3} = \\ \frac{ { - 155}^{4} }{{19}^{2} } \div \frac{ {155}^{3} }{ {19}^{3} } = \\ \frac{ { - 155}^{4} }{ {19}^{2} } \times \frac{ {19}^{3} }{ {155}^{3} } = \\ - 155 \times 19 = - 2945$
