Explanation:
The linear regression equation of the given set of points is required.
The required regression equation is [tex]y=1.98x+0.436[/tex]
The points are
x y xy x^2 y^2
1 1.24 1.24 1 1.5376
2 5.23 10.46 4 27.3529
3 7.24 21.72 9 52.4176
4 7.6 30.4 16 57.76
5 9.97 49.85 25 99.4009
6 14.31 85.86 36 204.7761
7 13.99 97.93 49 195.7201
8 14.88 119.04 64 221.4144
9 18.04 162.36 81 325.4416
10 20.7 207 100 428.49
55 113.2 785.86 385 1614.3112 Total
The image of the table is attached.
[tex]\sum y=55[/tex]
[tex]\sum y=113.2[/tex]
[tex]\sum xy=785.86[/tex]
[tex]\sum x^2=385[/tex]
[tex]\sum y^2=1614.3112[/tex]
[tex](\sum x)^2=55\times 55=3025[/tex]
n = Number of observations = 10
The equation of a line is given by
[tex]y=bx+a[/tex]
[tex]a=\dfrac{\left( \sum y \right)\left( \sum {{x}^{2}} \right)-\left( \sum x \right)\left( \sum xy \right)}{n\left( \sum {{x}^{2}} \right)-{{\left( \sum x \right)}^{2}}}\\\Rightarrow a=\dfrac{113.2\times385-55\times785.86}{10\times385-3025}\\\Rightarrow a=0.436[/tex]
[tex]b=\dfrac{n\left( \sum xy \right)-\left( \sum x \right)\left( \sum y \right)}{n\left( \sum {{x}^{2}} \right)-{{\left( \sum x \right)}^{2}}}\\\Rightarrow b=\dfrac{10\times785.86-55\times113.2}{10\times385-3025}\\\Rightarrow b=1.98[/tex]
The required regression equation is [tex]y=1.98x+0.436[/tex]

Millions of people were killed by Corona Virus in the recent outbreak in italy, change this sentence to active voice
Answers
Answer:
Corona Virus killed millions of people in the recent outbreak in Italy.
Explanation:
Changing voice or narration from an active to passive voice or vice versa requires a certain number of changes in the sentence structure and verbs used. Moreover, an active voice has the subject doing the verb while a passive voice has the subject being acted upon by the verb, meaning the verb is placed before the subject in a passive voice.
In the given sentence, the subject is "Corona Virus" while the verb is "killed". And it is given in the passive voice which is indicated by the use of "by" in the sentence.
Thus, the given sentence in the active voice is "Corona Virus killed millions of people in the recent outbreak in Italy."

Read the following text from a student essay. How can the writer best improve his or her organization? Competition can add a great deal of stress to students' lives. Like it or not, it's a part of classrooms, sports, and other after-school activities. For one, it can motivate students to work harder to achieve their goals. When students are challenged to strive for excellence, they often accomplish much more than what they may have initially expected. Also, even when students don't win at something, they still learn a valuable lesson: how to be a good sport about losing. However, even though it can be stressful, there are several reasons why students benefit from a little friendly competition.

Below is a list of facts
about exotic pets. Write one
paragraph of an argument describing
why exotic pets such as chimpanzees
and tigers should not be allowed in
homes. Select the details that would
best support your claim from the list
of fast facts.
Answers
Answer:
Both chimpanzees and tigers are considerably larger and stronger than the average human, with an adult chimpanzee being 3x stronger than a human. These animals would need careful handling as they have been known to kill people, not to mention that exotic pets kill at least 4 people yearly. The large size of these animals would mean that they would require large enclosures to accomidate them both as a sleeping habitat and an open area to stimulate them. The avarage American house size is 2, 287 square feet, tigeresses need 20 square kilometers of space while male tigers need 60 - 100 square meters of territory. Chimpanzees need 23 square meters per individual. This substantial amount of land required to house these exotic animals would not be typically accomidable. However, if you are able to procure the land to house such animals, then that also raises other issues regarding medical care and food for the animals.

Which mineral sample would weather faster, a sample of mica with a hardness of 3 on the Moh's hardness scale, or a topaz with a hardness of
8? Explain why (no links please!!! and if you don't know please don't answer just to get points thanks you!!!)
Answers
Answer:
I think it is Topaz.
Explanation:
The sample of mica with a hardness of 3 on the Moh's hardness scale would weather faster than the topaz with a hardness of 8. The mica sample would weather faster due to its lower hardness.
Hardness is a measure of a mineral's resistance to scratching or abrasion. In this case, mica has a hardness of 3, which means it is relatively softer compared to topaz, which has a hardness of 8. When exposed to weathering processes such as wind, water, temperature changes, and chemical reactions, softer minerals like mica are more susceptible to physical and chemical breakdown.
The lower hardness of mica makes it easier for external forces to cause erosion, disintegration, and alteration of the mineral's structure. In contrast, topaz's higher hardness makes it more resistant to these weathering effects, resulting in slower deterioration over time.

The widely criticized Dred Scott decision was then passed in 1857 and stated that an enslaved person who had escaped to a free state was still an enslaved person and that African Americans were not citizens.

In the last sentence of the first paragraph, the author repeats the word "presumably" in order to
A
portray the difficulty of assessing the moral quality of a nation's actions
B
remind the audience that they cannot be sure they understand people's motivations
undermine a view that he will go on to dispute in his argument
D
emphasize the vast power imbalance between those fighting in the described conflicts
E
caution his audience against forgetting the importance of a nation's sphere of influence
Answers
Answer: C
Explanation:
Presumably undermines because it says it isn't as they say.
In the last sentence, the repetition of the word "presumably" has the following purpose:
B. Remind the audience that they cannot be sure they understand people's motivations.
What does "presumably" mean?When we use the adverb "presumably" in a sentence, we wish to show our audience that what we are talking about is probably true, but it is not certain.For example, suppose you think the president of your country will issue a statement concerning the most recent act of violence that took place. However, you are not sure she will. You may say, "Our president will presumably issue a statement on the topic."With that in mind, we can see that the only option whose purpose is related to the meaning of "presumably" is letter B. The author is making it clear when he repeats "presumably" that we cannot be sure of people's motivations.Learn more about repetition here:
