When using supervised learning, the fit() technique requires two arrays of training data, but unsupervised learning only requires one array.
What does fit () do in regression?After the model is initialised, the "fit" method runs the algorithm on the training data. That is all it does, in essence. Thus, the machine learning model is trained using the training data by the sklearn fit approach. In the manufacturing industry, the term "form-fit-function" (FFF) refers to a part's distinguishing features (a single component that goes into the final build of your product, typically kept on an item master).
model.fit(): fit practise data This accepts the data X and the labels y as two arguments for supervised learning applications (e.g., model. fit(X, y)). Function at Cost. The cost function for linear regression is the Sum of Squares of Errors with the lowest value. Calculate the squared error sum for each and every available line.

Volume
I NEED THE ANSWER FAST HELPP PLEASE
Answer:
Step-by-step explanation:
Rounded volume: 524 cubic inches.
Step-by-step solution:
The formula for the volume of a sphere is:
Where r is the radius of the sphere.
The radius is half the diameter, therefore it is r=10/2=5
We plug it into the formula and we get:
Then we get:
If we do it in our calculator we get 523.599 that rounded to the nearest whole is 524 cubic inches .

Se tienen dos libros: uno de 240 página y otro de 160 páginas. Si los 2 libros están formados por cuadernillos con el mismo número de páginas (entre 16 y 28), ¿cuántos cuadernillos tienen en total los dos libros?
Answer:
Book of 240 pages has 12 booklets in total
Book of 160 pages has 8 booklets in total.
Total booklets both the books have in total = 20
Step-by-step explanation:
Given - There are two books: one of 240 pages and the other of 160 pages. If the 2 books are made up of booklets with the same number of pages (between 16 and 28),
To find - How many booklets do the two books have in total?
Proof -
Given that, Number of pages of a booklet is between 16 and 28.
So, The number that lies between 16 and 28 will have to divide the number of pages of both the books.
(Because given that both the books are made up of booklet with the same number of pages)
By inspection, we get
The number of pages of a booklet = 20
because
240/20 = 12 and 160/20 = 8
∴ we get
1 booklet = 20 pages
i.e.
20 pages = 1 booklet
⇒1 page = [tex]\frac{1}{20}booklet[/tex]
⇒240 pages = [tex]\frac{240}{20}booklet[/tex] = 12 booklet
So, we get
The book of 240 pages has 12 booklets in it.
Now,
1 page = [tex]\frac{1}{20}booklet[/tex]
⇒160 pages = [tex]\frac{160}{20}booklet[/tex] = 8 booklet
So, we get
The book of 160 pages has 8 booklets in it.
∴ we get
Book of 240 pages has 12 booklets in total
Book of 160 pages has 8 booklets in total.
So, Total booklets both the books have = 12 + 8 = 20

Use your answer from Part I to find the slope of a line going through each set of points. Then
describe the line as positive, negative, zero, or undefined. Show your work and explain your
answer.
A. (5, 7) and (-4,-2)
B. (1, 3) and (1, -10)
Answer:
Step-by-step explanation:
to find the slope of a line that passes for two given points we can use this formula (y2-y1)/(x2-x1). x and y inidcate the coordinates of the two points.
A (-2-7)/(-4-5) = (-9)/-9 = 1 (m is positive)
B (-10-3)/(1-1)) = the denominator is equal to zero, so the division is impossibile. This mean that m is undefined and the line is parallel to y axis
Which of the following is the solution (x,y) of the system of equations x-2y = 2 and -x+2y = 2
Answer:
Step-by-step explanation:
x-2y = 2
-x+2y = 2
set 1st eq. equal to 2nd equation since they both equal 2
x -2y = -x + 2y
2x = 4y
x = 2y
1/2x = y

PLS HELP ME!!!!! Students are selling raffle tickets for a school fundraiser. They collect $24 for every 10 raffle tickets they sell. Suppose M is the amount of money the students collect for selling R raffle tickets. Write an equation that reflects the relationship between M and R.
Answer: M=2.4R
Step-by-step explanation:
If 24 dollars are collected for every 10 tickets we can find the cost of each ticket like so...
24/10=2.4
so now we can set up our equation...
M=2.4R
this means we get M amount of money for R number of tickets sold at a rate of $2.40 each.

Step-by-step explanation:
A textbook company states that the average time a student needs to take a quiz from its book is 30 minutes with a standard deviation of 3 minutes. A teacher using the book is not sure that this is correct for her classes and wants to check. She collects data on 10 random students and finds that the average time to take the quiz was only 25 minutes. As a result, the teacher performs a two-tailed hypothesis test with a significance level of 5%. Which conclusion is valid based on the results of the test
Answer:
We conclude that her students, on average, do not take 30 minutes on the quiz, contrary to what the textbook company states.
Step-by-step explanation:
We are given;
Population mean; μ = 30 minutes
Population standard deviation; σ = 3 minutes
Sample size; n = 10
Sample mean; x¯ = 25
Significance level = 5% = 0.05
Let's define the hypotheses;
Null hypothesis; H0: μ = 30
Alternative hypothesis: Ha: μ ≠ 30
Let's find the test statistic;
z = (x¯ - μ)/(σ/√n)
z = (25 - 30)/(3/√10)
z = -5.27
From online p-value from z-score calculator attached using, z = -5.27, significance level = 0.05, two tailed hypothesis, we have;
p < 0.00001
This is less than the significance level, and so we will reject the null hypothesis and conclude that Her students, on average, do not take 30 minutes on the quiz, contrary to what the textbook company stated.
Answer:
A. Her students, on average, do not take 30 minutes on the quiz, contrary to what the textbook company stated.
