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]

Explanation:
A complex sentence is one that has an independent clause along with one or more dependent clauses. This means that the independent clause, as well as the dependent clause together, make the complex sentence.
In a complex sentence, the dependent clause starts with a subordinating conjunction. Therefore, among the given sentences, the first sentence contains a subordinating conjunction (as), a dependent clause, and an independent clause.
The second sentence is a compound sentence as it contains a 'coordinating conjunction'.
The third sentence is a simple sentence with an independent clause and no dependent clause.
Thus, the correct answer is the first sentence.

The speaker uses another type of allusion in literature, "But the blacks can't do Shakespeare, they have no experience." Derek Walcott's had a deep knowledge of Shakespeare.

Explanation:
I identified two allusions and I discussed how allusions connect to the speaker’s perspective. Hence, option A and C are correct.
What is allusions?We use an allusion when we make a suggestion and assume the other person will understand the reference. For instance: Chocolate is his Kryptonite. In this context, the word "kryptonite" refers to or denotes the superhero Superman.
A writer makes an allusion when they make a reference to a well-known person, thing, place, or event in order to help the reader better understand what they've written by creating a connection between the reference and the work.
Donuts' scent is like kryptonite to me. She arrived looking like Venus. My weakness has always been that. I wish I could just click my heels and go home.
Thus, option A and C are correct.

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.
