What is the median of the following set: 2, 4, 6, 8, and 10?

Answers

Final answer:

The median of the set of numbers 2, 4, 6, 8, and 10 is 6 because the median is the middle number in a sorted, ascending or descending, sequence of numbers.

Explanation:

In the field of statistics, the median is the middle value in a set of data that has been arranged in ascending order. If the total number of data values is odd, the median is the middle value. When the count of data values is even, the median is computed as the average of the two middle values. The given data set is 2, 4, 6, 8, 10. Since this is an odd set of numbers, we set the number in the middle as the median. Thus, the median value here is 6.

Which object would best be identified by a periodic Doppler shift in a star's spectrum along with a dip in the stars light intensity?a black hole
a nebula
a comment
a planet

Answers

The answer would be a planet. Planets revolve around stars, which means there will come a point where the planet is between the star and our field of vision towards the star. This point will be where the star's radiation will have the lowest intensity. As the planet moves, the intensity will change. The effect is comparable to a lunar or solar eclipse.

Answer:

D. a planet

Which is most likely why many scientists reject the cold fusion theory?

Answers

Since there are no choices provided for this question, the answer to why many scientists reject the cold fusion theory is that the experiment by Fleischmann and Pons that had the strongest claim was found out to be flawed. Many scientists who also replicated the experiment failed to obtain positive results which further weakened the claim for cold fusion theory.

quick check answers: (you're welcomeee)

1. d

2. d

3. d

4. c

5. d

6. b

100% correct as i just finished it.

ANSWER: the original results have not been replicated consistently and reliably. | the only way for cold fusion to become a reliable theory is if scientists repeat this experiment is to make sure the results are repeatable. If a scientist cannot reproduce it anywhere in the world, then its deemed unaccepted as a theory.

The process of boiling a mixture so that one part will evaporate, then cooling or condensing the evaporated liquid, and finally collecting the cooled liquid, is known asa. settling.
b. filtration.
c. distillation.
d. evaporation.

Answers

The answer is C. Distillation. Distillation is a common process for separating liquid mixtures by using the principle of volatility and boiling point. For a liquid mixture with two liquid components A and B, A will have a lower boiling point or higher volatility than B. By boiling the mixture at the boiling point of component A, only component A will evaporate from the mixture. The evaporated gas will then be cooled to condense component A back to a liquid.

The answer would be C. :))
