Consider the 912 people to be a population. Let X be the number of times per week a person dines out for a person sampled at ran

konstantin123 [22]

Answer:

x`= ∑x P (x)

Step-by-step explanation:

The mean ca be calculated using the formula

x`= ∑x P (x) where x takes the value from 1,2,3,4......i

The sampling distribution is the probability distribution or the relative frequency distribution of the means X` of all possible random samples of the sample size that could be selected from a given population. The mean of this distribution is represented by Ux` and the standard deviation which is called the standard error of the mean S.E (X`)

The mean of the sampling distribution is equal to the population mean that is ux`= u whether the sampling is done with or without replacement.

Liono4ka [1.6K]

Answer:

x=13/4 or -1

Step-by-step explanation:

factorize the fraction

(4x^2+4x)(-13x-13)

4x(x+1) -13(x+1)

(4x-13)(x+1)

x=13/4 or x=1

A book is to be randomly chosen from the library. The probability that a randomly-chosen book is fiction is

Sveta_85 [38]

Using Venn probabilities, and supposing the incomplete probabilities, it is found that there is a 0.35 = 35% probability that a randomly-chosen book from the library is fiction or has a white cover.

<h3>What is a Venn probability?</h3>

In a Venn probability, two non-independent events are related with each other, as are their probabilities.

The first step to solve a problem using Venn probabilities is identifying the events. In this problem, they are:

Event A: Fiction.

Event B: White cover.

The "or probability" is given by:

$P(A \cup B) = P(A) + P(B) - P(A \cap B)$

In this problem:

The probability that a randomly-chosen book is fiction is 0.15, hence $P(A) = 0.15$ .

The probability that randomly-chosen book has a white cover is 0.3, hence $P(B) = 0.3$

The probability that a randomly-chosen book is fiction and has a white cover is 0.1, hence $P(A \cap B) = 0.1$

Then:

$P(A \cup B) = P(A) + P(B) - P(A \cap B)$

$P(A \cup B) = 0.15 + 0.3 - 0.1$

$P(A \cup B) = 0.35$

0.35 = 35% probability that a randomly-chosen book from the library is fiction or has a white cover.
