Answer:

Explanation:

the author name is Vera Tripodi (u got an extra l in there) n paper is "The Value of Diversity and Inclusiveness in Philosophy. An Overview." the main theme is that individuals are marginalized in study of philosophy due to the big gender gap.

philosophy is highly subjective n its study is heavily influenced by its scholars. its well known among academia that there is a gender gap - most professors and researchers are men with very few women. while that may not be significant in experiment-based subjects like science and engineering, that is not the case for many humanity studies. philosophy is particularly personal and the perspective of a male scholar can be very different from that of a female colleague. this leads to the conclusions drawn from such studies may be biased or even discriminated female population.

Answer:

Explanation:

The argument was that study of philosophy was biased and treated women different from men. The author cited one of the earliest philosopher:  Aristotle. His "notions of “form” and “matter” reflect sexual differences: the former is intrinsically linked to “being male” and latter to “being feminine”. This gender association poses a problem for feminists: Aristotelian matter and form are not treated as equal and the form has priority over the matter." Her conclusion is that "the sexism of the distinction between form and matter is inherent to Aristotle’s metaphysic."

In anatomy class, test scores were determined to be 20 times the number of hours, h, the student studied plus 4. Which of the following functions best describes a students test score depending on the number of hours, h, that the student studies.

Answers

Answer: 20h + 4

Explanation:

Based on the information given in the question, the function that best describes a students test score depending on the number of hours, h, that the student studies will be:

= (20 × h) + 4.

= 20h + 4

Let's assume the student studied for 3 hours, the test score will be:

= 20h + 4

= 20(3) + 4

= 60 + 4

= 64.

2,7,8,3,12,9 What is the next
number?

Answers

Answer:

We have to determine the pattern of numbers followed in the sequence 2, 7, 8, 3, 12, 9.

Do a grouping of the sequence into two groups. Let the first group be 2, 7, 8 and the second group be 3, 12, 9

There is a difference of 1 in the pair 2 and 3, a difference of 5 in the pair 7 and 12 and a difference of 1 in the pair 8 and 9

This means there would be a difference of 5 in the next pair.

So, adding 5 to the first number to the third pair.

Hence, the next number will be 13.
