Answers

Answer 1

An archer hoot arrow at a target with expected value E(X) = 6.7.

EXPECTED VALUE OF SCORE

≤ X ≤ 6, and 2 point if X > 6.

What is the expected number of points scored by the archer?

The expected number of points scored by the archer can be calculated by multiplying the probability density function (pdf) of the distance X by the point value at each distance and then summing the results. This is known as the expected value.

E(X) = (1/10e⁻²/108) + (1/10e⁻⁶/10 - 1/10e⁻²/10)5 + (1 - 1/10e⁻⁶/10) × 2

Expected value E(X) = 6.7

The expected score is the sum of all possible scores multiplied by their respective probabilities. It can be calculated by integrating the product of the score function and the probability density function over the entire range of possible values of the variable.

The appendix, an extension of the large intestine appears, although this is debated, to have little
function in humans. What is the appendix an example of in terms of evidence for evolution?​

Answers

Answer: Vestigial organ

Explanation:

Vestigial organs are those organs which were functional in ancestral organisms belonging to the same species but due to the course of evolution of body forms they become non-functional. They can be found in the body either in the same form as used to appear in the ancestors or in rudimentary or degenerated forms.

The human appendix is one of the examples of vestigial organs. It looks like a narrow tube which forms a link with a colon of the large intestine. It was functional in human herbivorous ancestors as it used to help in digestion of variety of vegetables and other plant products. The change of diet along with due course of evolution caused the appendix to become useless. But the appendix physical form remained the same in humans.

Explanation:

Respiration is a redox reaction on which sugar is oxidized to produce energy .

What is respiration?

Cellular respiration is a sequence of chemical events that break down glucose to produce ATP, which can then be utilized as energy to power a variety of reactions throughout the body. Glycolysis, the citric acid cycle, and oxidative phosphorylation are the three basic processes that take place during cellular respiration.

Animals and humans use breathing to get the oxygen they need for cellular respiration. In order to create ATP, the nutrients you absorb through food must be broken down by the oxygen you breathe, while carbon dioxide and  water are generated as waste products.
