The best-fitting regression model for the data plot given is linear decreasing. Therefore, option B is the correct answer.
What is linear regression?Linear regression is a linear approach for modelling the relationship between a scalar response and one or more explanatory variables. The case of one explanatory variable is called simple linear regression; for more than one, the process is called multiple linear regression.
In the given graph, the data plot shows the decreasing order.
Therefore, option B is the correct answer.

You earn 3653 points in level 1 of a video game and
2375 points in level 2. After level 3, your point total is
8876. Write an equation you can use to find the
number of points (p) you scored in level 3.
Answers
Answer:
8876-(3653 +2375)
Step-by-step explanation:
So your total is 8876. On the first and the second level of the game you scored 3653 and 2375. But when you where done playing the third level your total from all of the levels ended up to be 8876. So if you wanted to find how much points you got on level 3, then you would add 3653 + 2375, then suntract the total of that from 8876.

If an athlete is tested for a certain type of drug usage, then the test will come out either positive or negative. However, these tests are never perfect. Some athletes who are drug free test positive, and some who are drug users test negative. The former are called false positives; the latter are called false negatives. Assume that 5% of all athletes use drugs, 4% of all tests on drug-free athletes yield false positives, and 10% of all tests on drug users yield false negatives. Define the events as follows: Free: an athlete is drug free. User: an athlete is a drug user. Positive: an athlete is tested positive Negative: an athlete is tested negative. Then, we have P(User) - 0.05, P(Positive Free) = 0.04, and P(Negative User) - 0.10, What is the probability that a randomly selected athlete tests positive, P(Positive)? a. 0.083 b. 0.127 c. 0.308 d. 0.312

Answer:
[tex]4x^{6}2y^{-2}[/tex]
Step-by-step explanation:
We can use a property I like to call SEi-F. (Subtract Exponents in a Fraction)
But first, there is an exponent outside of the parentheses in both places. We can use the Power of Parentheses to simplify and then use the SEi-F.
We will start with the x in the numerator.
3*4 = 12
Now for the y in the numerator.
4*4 = 16
Our new numerator is [tex]4(2x^{12}y^{16})[/tex]
We do need to simplify the numerator one more time to get rid of the 4 outside the parentheses.
We will start with x's coefficient.
2*4 = 8
Now for y's coefficient.
1**4 = 4
*y seems to have no coefficient, but if so, it has a coefficient of 1. This applies to other variables.
Our final simplified numerator is [tex]8x^{12}4y^{16}[/tex].
Repeat with the denominator.
Try it yourself!
Make sure that when you finish, you finish the fraction.
After completing the denominator, your completed fraction should be:
[tex]\frac{8x^{12}4y^{16}}{4x^{6}2y^{18}}[/tex]
Now we can use the SEi-F to complete the problem.
Start with x.
8x - 4x = 4x
12 - 6 = 6
The first term is [tex]4x^{6}[/tex].
Now for y.
4y - 2y = 2y
16 - 18 = -2
The second term is [tex]2y^{-2}[/tex]
The complete, simplified equation is [tex]4x^{6}2y^{-2}[/tex].
I could be wrong on the answer, but the work should be correct.
Hope this helps. Have a nice day. Oh, and one more thing. Surprised I'm not stealing points?

Results from previous studies showed 76% of all high school seniors from a certain city plan to attend college after graduation. A random sample of 200 high school seniors from this city reveals that 162 plan to attend college. Does this indicate that the percentage has increased from that of previous studies
Answers
Answer:
Given that 162 is 81% of 200, we can affirm that the percentage of students who will attend college after high school has increased.
Step-by-step explanation:
Given that results from previous studies showed 76% of all high school seniors from a certain city plan to attend college after graduation, if a random sample of 200 high school seniors from this city reveals that 162 plan to attend college, to determine if this indicates that the percentage has increased from that of previous studies, the following calculation must be performed:
200 x 0.76 = 152
200 = 100
162 = X
162 x 100/200 = X
16,200 / 200 = X
81 = X
Thus, given that 162 is 81% of 200, we can affirm that the percentage of students who will attend college after high school has increased.

John enlarged one side of his square flower bed by 8 ft to make it into a rectangle. The area of the new flower bed is 3 times the area of the old one. What was the length of the side of the old flower bed.
Answers
Answer:
4 ft.
Step-by-step explanation:
We can consider the orignial square's sides to be x, so area of the original figure: [tex]x^{2}[/tex]
The new rectangle's sides will be x and x+8, so the area of the new figure will be x^2+8x.
We know that the new area is 3 times the old one. So our equation will be:
x^2+8x=3x^2
our answer will be x=4.
Therfore, the length of the side of the old flower bed is 4 ft.
Applying the area of rectangle, an equation is created to find the length of the side of the old flower bed, which is: 4 ft.
What is Area of a Rectangle?Area = length × width.
Thus:
Let x represent the side of the square old flower bed
Area of old flower bed = x × x = x²
Dimensions of new rectangular flower bed:
Width = x
Length = x + 8
Area = 3(x²) = 3x²
Thus:
x(x + 8) = 3x²
x² + 8x = 3x²
8x = 3x² - x²
8x = 2x²
8x/2 = x²
4x = x²
4x/x = x²/x
4 = x
x = 4
Thus, applying the area of rectangle, an equation is created to find the length of the side of the old flower bed, which is: 4 ft.
