(2 pts)
Answers
Answer:
Explanation:
Given the data:
X ___ : 0____ 1 ___ 2 ____ 3 ____ 4
P(X)__: 0.35_0.3___, b ___0.05_ 0.05
Σp(x) = 1
Hence,
0.35 + 0.3 + b + 0.05 + 0.05 = 1
0.75 + b = 1
b = 1 - 0.75
b = 0.25
The mean :
E(x) = Σ(X * p(x))
E(x) = (0*0.35)+(1*0.3)+(2*0.25)+(3*0.05)+(4*0.05)
E(x) = 0 + 0.3 + 0.5 + 0.15 + 0.2 = 1.15
Standard deviation = sqrt(Var(x))
Var(x) = Σx²p(x) - E(x)
Σx²p(x) = (0^2 * 0.35)+(1^2 * 0.3)+(2^2 * 0.25)+(3^2 * 0.05)+(4^2 * 0.05)
= 2.55 - 1.15
= 1.4
Sqrt(1.4) = 1.183

A self-description

Answers
The word essay that answers the question: Who am I, and who am I in relation to others is given below.
Who am I, and who am I in relation to othersWho am I? This is a question that has been pondered by philosophers and scholars for centuries, and it is a question that each of us must answer for ourselves. At its core, it is a question of identity and self-awareness.
To begin, I will start with a self-description. I am a complex and multifaceted individual, with many different aspects to my personality and character. I am a student, a friend, a daughter, a sister, and a member of my community. I am also a person who is constantly learning, growing, and evolving. I am someone who is deeply curious about the world around me, and I am always seeking to expand my knowledge and understanding of the world. I am also a person who values honesty, integrity, and kindness. I believe that these values are important not only for my own personal growth, but also for the well-being of those around me.
When it comes to how I am similar to and different from those around me, I believe that there are many ways in which I am both similar and different. For example, like many others, I am someone who is passionate about my studies and my future career. I am also someone who values my family and friends and enjoys spending time with them. However, I am also different in many ways. For example, I am someone who is deeply interested in the world of science and technology, and I am always eager to learn more about the latest advancements in these fields. Additionally, I am someone who is deeply interested in the arts, and I enjoy expressing myself creatively through writing and painting.
Finally, I would like to discuss how my performances shape communication I have with those around me. I believe that my performances, whether they be in the classroom, in my personal life, or in my community, have a significant impact on the way that I communicate with others. For example, when I am performing well academically, I am able to communicate more effectively with my professors and classmates, and I am able to contribute more meaningfully to class discussions.
In conclusion, I am a complex and multifaceted individual, with many different aspects to my personality and character. I am similar to and different from those around me in many ways. And my performances shape the way I communicate with those around me. I am constantly learning and growing, and I believe that this ongoing process of self-discovery is what makes life so exciting and meaningful.

A linear function is one in which the data points lie on a straight line. If you examine the data set, you'll notice that the slope is equal to 3, which means that for every increase of 1 in the x value, the y value increases by 3. The graph of this equation would be a straight line that goes upward. As the value of x increases, the value of y increases as well, and the two variables are proportional.
The relationship between x and y is thus linear. Therefore, in the given table, we notice a pattern that shows how the value of y is related to the value of x. As x increases, y also increases in a linear fashion, and we can calculate y by using the equation y=3x +1.

Explain a recent trend in the location of dairy farms with respect to consumer locations.
Answers
In recent years, there has been a growing demand for locally produced and fresh dairy products, such as milk, cheese, and yogurt. This trend has led to an increase in the number of small-scale dairy farms located closer to urban and suburban areas, where there is a high concentration of consumers.
Small-scale dairy farming typically involves fewer cows and emphasizes animal welfare and sustainable farming practices. These farms often sell their products directly to consumers through farmers' markets, co-ops, and online platforms, cutting out the middleman and offering fresher and more personalized products to consumers.
The rise of localized and small-scale dairy farming has also been driven by consumer preferences for organic and non-GMO dairy products. These products are often associated with smaller-scale farming operations that prioritize sustainability and animal welfare, and are located closer to urban areas to reduce transportation and distribution costs.
Overall, the trend towards localized and small-scale dairy farming represents a shift in consumer preferences towards more sustainable and transparent food production, and has implications for the broader agricultural industry as well as the health and well-being of consumers.

Which of these conditions would likely cause the tectonic plates of Earth to stop moving?
Answers
Answer:
The correct option is;
A. The Earth's crust and mantle reach thermal equilibrium
Explanation:
The movement of the tectonic plates in the theory of plate tectonics is believed to be due to the heating of the mantle from the Earth's core causing convection currents which causes movement of molten rock in the Earth's mantle.
The convection current movement caused by the rising of the heated mantle material close to the Earth's crust and the sinking of cooled material back towards the core is similar to a stove boiling water in a pot.
Therefore, when the Earth's crust and mantle are at thermal equilibrium, there will be no convection current and the tectonic plates of Earth will stop moving.

"4. The dictatorship of the proletariat must be the lever for the immediate expropriation of capital and for the abolition of private property in the means of production and their transformation into national property. The nationalization of large-scale industry (nationalization being understood as the abolition of private ownership and transference to the ownership of the proletarian State, to come under the socialist management of the working class) and of its organizing centres, the banks; confiscation of the estates of the large landowners and nationalization of capitalist agricultural production; monopoly of wholesale trade, nationalization of large houses in towns and on large estates; introduction of workers’ management and centralization of economic functions in the hands of agencies of the proletarian dictatorship—these are the essential problems of the day.
5. In order to safeguard the socialist revolution, to defend it against internal and external enemies, to give aid to other national sections of the fighting proletariat, etc., it is essential to disarm the bourgeoisie and their agents completely, and to arm the proletariat.
6. The world situation today demands the closest possible contact between the different sections of the revolutionary proletariat and a complete union of the countries where the socialist revolution has already triumphed.”
