Find the standard deviation of the following R.V. Show all work...no calculator shortcuts...but then check with 1-var stats.
X 7 15 28
P(X) 0.2 0.49 ?
Round to FOUR decimal places.
Answer:
7.6997
Explanation:
Given :
X : ____7 ____ 15 ____ 28
P(X) __0.2 ___0.49 ____?
ΣP(x) = 1
0.2 + 0.49 + a = 1
a = 1 - 0.69
a = 0.31
Standard deviation = sqrt(Variance(x))
Variance = Var(X) = Σx²p(x) - E(x)²
E(x) = Σx*p(x) = (7*0.2) + (15*0.49) + (28*0.31) =
E(x) = 17.43
Σx²p(x) = (7^2 * 0.2) + (15^2 * 0.49) + (28^2 * 0.31) = 363.09
Var(X) = Σx²p(x) - E(x)²
Var(X) = 363.09 - 17.43^2
Var(X) = 363.09 - 303.8049
Var(X) = 59.2851
Standard deviation = sqrt(59.2851)
Standard deviation = 7.6996818
= 7.6997

Explain ONE way in which capitalism influenced the consumer revolution in the period 1750-1900.
Answer:
Capitalism is an economic system through which the large-scale production of goods and services is advocated, their commercialization in the market privately, and the accumulation of capital to use it to promote more economic production and more consumption.
Thus, through this system, a mass production was generated and therefore consumption, generating that it became purely subsistence to cover not only the basic needs of individuals, but also promoting the consumption of goods of luxury, leisure and, in general, all those that exceeded food or health issues.

Describe the relationship between the social history of Texas and the political characteristics of the state’s diverse population.
Please help i at least need 3 sentences long!
The correct answer to this open question is the following.
Although there are no options attached we can say the following.
The relationship between the social history of Texas and the political characteristics of the state’s diverse population. can be traced back to when the territory of Texas belonged to the Mexican government. Then, we can identify the times of Stephen F. Austin trying to colonize the Texas territory, negotiating with the Mexican authorities to grant the authorization to bring Anglo people to Texas. Then, fateful episodes such as the Alamo, and later, the victory of the Texan army in the Battle of San Jacinto, in Galveston. After being a Republic, Texas was annexed to the Union but there has always been a mixture of the Anglo culture with the Mexican culture even today. That intermingling of belief systems, culture, and traditions is one of the notorious things that characterizes Texas, especially cities such as San Antonio, El Paso, Houston, and Dallas.
Explain federalism and the powers of the state in a constitutional context.
help!
The correct answer to this open question is the following.
Although there are no options attached, we can say the following.
Under the United States Constitution, the concept of federalism means that there is a division of powers between state and national governments,.
Under this constitutional division, the country is governed by one federal government and state governments. They have a direct relationship and sometimes they have encountered some conflicts due to the application of legislation.
The federal government is dived into three branches. The executive branch is the President of the United States. The legislative branch that is the Congres divided into two chambers. The upper chamber or Senate, and the lower chamber or House of Representatives. And finally, the judicial power that is the US Supreme Justice.
These three branches work under the system of checks and balances, which means that none of the three have more power than the others.
The states have a similar structure.

Answer:
During the five years prior to NAFTA, maquiladora employ- ment grew 47 percent. But over the first five years after NAFTA, employment growth soared 86 percent (Chart 1). This growth was not simply a matter of existing plants taking on more workers but of rapid expansion in the number of plants.

If, as the world has long agreed, a very great amount of instruction will not make a wise man, still less will a very mediocre amount of instruction make a wise woman. And the most mischievous form of feminine silliness is the literary form, because it tends to confirm the popular prejudice against the more solid education of women.
When men see girls wasting their time in consultations about bonnets and ball dresses, and in giggling or sentimental love-confidences, or middle-aged women mismanaging their children, and solacing themselves with acrid gossip, they can hardly help saying, “For Heaven’s sake, let girls be better educated; let them have some better objects of thought—some more solid occupations.” But after a few hours’ conversation with an oracular1 literary woman, or a few hours’ reading of her books, they are likely enough to say, “After all, when a woman gets some knowledge, see what use she makes of it! Her knowledge remains acquisition instead of passing into culture; instead of being subdued into modesty and simplicity by a larger acquaintance with thought and fact, she has a feverish consciousness of her attainments; she keeps a sort of mental pocket-mirror, and is continually looking in it at her own ‘intellectuality;’ she spoils the taste of one’s muffin by questions of metaphysics; ‘puts down’ men at a dinner-table with her superior information; and seizes the opportunity of a soirée2 to catechise3 us on the vital question of the relation between mind and matter. And then, look at her writings! She mistakes vagueness for depth, bombast for eloquence, and affectation for originality; she struts on one page, rolls her eyes on another, grimaces in a third, and is hysterical in a fourth. She may have read many writings of great men, and a few writings of great women; but she is as unable to discern the difference between her own style and theirs as a Yorkshireman is to discern the difference between his own English and a Londoner’s: rhodomontade4 is the native accent of her intellect. No—the average nature of women is too shallow and feeble a soil to bear much tillage;5 it is only fit for the very lightest crops.”
It is true that the men who come to such a decision on such very superficial and imperfect observation may not be among the wisest in the world; but we have not now to contest their opinion—we are only pointing out how it is unconsciously encouraged by many women who have volunteered themselves as representatives of the feminine intellect. We do not believe that a man was ever strengthened in such an opinion by associating with a woman of true culture, whose mind had absorbed her knowledge instead of being absorbed by it. A really cultured woman, like a really cultured man, is all the simpler and the less obtrusive for her knowledge; it has made her see herself and her opinions in something like just proportions; she does not make it a pedestal from which she flatters herself that she commands a complete view of men and things, but makes it a point of observation from which to form a right estimate of herself. She neither spouts poetry nor quotes Cicero6 on slight provocation; not because she thinks that a sacrifice must be made to the prejudices of men, but because that mode of exhibiting her memory and Latinity7 does not present itself to her as edifying or graceful. She does not write books to confound philosophers, perhaps because she is able to write books that delight them. In conversation she is the least formidable of women, because she understands you, without wanting to make you aware that you can’t understand her. She does not give you information, which is the raw material of culture—she gives you sympathy, which is its subtlest essence.
The author writes approvingly of the cultured woman’s restraint in quoting poetry and Latin authors (paragraph 3, sentence 4) because
the author respects the woman’s desire to conform to received notions of feminine modesty
A
the author endorses the woman’s decision to tolerate male prejudices against educated women
B
it shows the woman’s ambition to produce original work instead of parroting the works of canonical authors
C
it reveals the woman’s thoughtful consideration of the effects of her own behavior on others
D
it suggests that the woman has wisely devoted more time to studying modern languages than to studying classical literature
E
Answer:
D. it reveals the woman’s thoughtful consideration of the effects of her own behavior on others
It reveals the woman’s thoughtful consideration of the effects of her own behavior on others. The correct option is D.
What is culture?Culture refers to a group's or society's shared beliefs, values, customs, behaviours, and artefacts.
It includes a wide range of human activities such as language, art, music, religion, social habits, and technology. Culture is passed down from generation to generation through socialisation.
The author writes that the cultured woman does not recite poetry or quote Cicero at the slightest provocation, not because she believes it is necessary to make a sacrifice to men's prejudices, but because that mode of displaying her memory and Latinity does not appear to her as edifying or graceful.
This implies that the woman is considering the impact of her actions on others and has chosen to act in a more graceful and considerate manner.
Thus, the correct option is D.
