Answer:

mean of all 30 students is 69

Explanation:

given data

students = 30

mean = 29

μ = 68 points

student scored = 98 points

to find out

What is the mean for the class of all 30 students

solution

we know here mean score of 29 students is 68

so sum of score is here = 29 × 68

sum of score = 1972

so

sum of 30 students score is = sum of 29 students score + missing score

sum of 30 students score is = 1972 + 98

sum of 30 students score is = 2070

so

mean of all 30 students is = \frac{sum of 30 students}{30}

mean of all 30 students is = \frac{2070}{30}

mean of all 30 students is 69

Semmy [17]

Answer:

<h3>Individualistic fallacy.</h3>

Explanation:

Individualistic fallacy is one among the five fallacies people should avoid when they think about racial denomination. According to Desmond and Emirbayer, it is an <u>individualistic fallacy</u> to think of racism as being only about ideas and prejudices.

In this fallacy, racism is seen as something that emerges from ideas and prejudices. People with this fallacy think that racism is the collection of hateful and prejudiced thoughts that racist individuals have for other groups of people. However, people with this fallacy does not consider the intentionality of a racial act. They think all racial acts are hateful and nasty.

Therefore, Desmond and Emirbayer try to establish that racism is not only about intentional thoughts and actions but it also includes unintentional thoughts  and habits that social institutions have implanted.
