A fitness center piloted two new programs to help people reduce stress levels and maintain a healthy lifestyle. After one month, 112 of the 125 people who volunteered for a program in mindfulness reported a reduction in stress levels, and 110 of the 135 people who volunteered for a yoga program reported a reduction in stress levels. The fitness center wants to investigate whether there is a significant difference between the proportions of all people in the two programs who would report reductions in stress levels. Have the conditions for inference been met?
A
No, because the samples were not selected or assigned using a random method.
B
No, because the sizes of the samples are too large compared to the size of the population.
C
No, because the normality of the sampling distribution cannot be assumed; the number of people who did not experience stress relief is not large enough.
D
Yes, because all conditions for making statistical inference have been met.

A) Malcolm X states that the civil rights struggle must be elevated to a human rights struggle. Why does he believe that this distinction is important? B) Based on this reading, what is black nationalism?

Answers

Answer:

Malcolm X radically transformed the idea of the struggle for equality, proclaiming the famous formula for the struggle against segregation, but for separation. Paying attention to the fundamental difference between these concepts, he emphasized that segregation is imposed on lower ones by those who are superior to them, and separation is what is done voluntarily, by two equal parties for their mutual well-being. He sharply criticized the practice of nonviolent action.

In the spring of 1964, X officially left the “Nation of Islam,” declaring the creation of his own organization, the Muslim Mosque. It was based on a pronounced “ethnic agenda,” as Malcolm declared on March 12, 1964 in the so-called Declaration of Independence: “Black political nationalism will be our political philosophy.” A month later, speaking at a rally in Cleveland, he deciphered this concept as follows: “The political philosophy of black nationalism means that a black person must control politics and politicians in his own community.”

Many consider Malcolm X the most influential orator of the Nation of Islam after Elijah Muhammad. He is often recognized as the ‘creator’ of success associated with a sharp increase in the size of the organization: according to one of the authors, from the beginning of the fifties to the beginning of the sixties, the number of members of the Nation increased from five hundred to twenty-five thousand, while the other indicates the numbers 1200 and 50,000 or 70,000, respectively. He managed to inspire the famous boxer Cassius Clay, who joined the Nation.

It is impossible to cross out Malcolm X from the history of the struggle for the civil rights of African-Americans in the USA. Indeed, despite all his shortcomings and mistakes, he, in louder manner and more furiously than other figures of that era formulated a demand for the US authorities to eliminate any discrimination against African Americans and begin to treat a black citizen as a sovereign human person.

A marginal phenomenon in the early 20th century, black nationalism, less than 100 years later became mainstream in the American political, social, and cultural spheres, giving rise to such movements as the Black Lives Matter.  

Explanation:

i got it from somewhere else.

The reason why Malcolm X believes that the civil rights struggle should be elevated to a human rights struggle is that basic rights were for everyone and not just for one race.

What is Civil Rights Movement?

This refers to the historical period in American history when the black community stood up to institutional racism and inequality to demand equality.

Hence, we can see that black nationalism is the belief in the black race and the desire to identify with the black people as a race and also a form of identity.

Question 11

options. The following table shows the number of students who selected each elective for the 1,500 students at the high
school.

art 385
music 365
physical education 380
engineering 370
total 1,500

One student from the school will be selected at random. What is the probability the selected student chose the art elective
and the music elective?
А 0
B 385/1500
C 365/750
D 750/1500
E 385/750

Answers

Answer:

D. [tex]\frac{750}{1500}[/tex] would be my first answer, but make sure it's not a trick question. The answer could possibly be A. 0

Explanation:

Since we are choosing from the entire highschool, we know that our denomination should be 1500, which is the total number of students in the school.

Furthermore, if we want to select either a student with a music or art elective, then there are 385 students with art electives and 365 students with music electives.

So, we just add them up and divide by the total number:

[tex]\frac{385+365}{1500}[/tex] = [tex]\frac{750}{1500}[/tex] as the probability.

Note: I'm not sure if it was a trick question though. The questions asks for the probability that a student chose both an art and a music elective, which is impossible because "each student chooses an elective," not multiple.

In this case, the answer would be 0.

A 230 kg motorcycle zooms away from a red light with a force of 13,800 Newtons.
What is the acceleration of the motorcycle in m/s??

come someone help? ASAP!!

Answers

Answer:

The acceleration will be "60 m/s²".

Explanation:

The given values are:

Mass,

m = 230 kg

Force,

F = 13,800 N

Acceleration,

a = ?

As we know,

⇒  [tex]Force = Mass\times Acceleration[/tex]

Then,

⇒  [tex]Acceleration=\frac{Force}{Mass}[/tex]

On substituting the values, we get
