enlist education system found in Nepal
Answer:
Education in Nepal was long based on home-schooling and gurukulas.[citation needed] The first formal school (Durbar School), established by Jung Bahadur Rana in 1853, was intended for the elite. The birth of Nepalese democracy in 1951 opened its classrooms to a more diverse population.[citation needed] Education in Nepal from the primary school to the university level has been modeled from the very inception on the Indian system, which is in turn the legacy of the old British Raj.[1]

.75-.25 is .5
1/2 is equal to .5 so .5 +.5 is 1
Answer:
0.75 - 0.25 + 1/2
convert the decimals to fractions
that's
0.75 = 3/4
0.25 = 1/4
We get
3/4 - 1/4 + 1/2
Find the common denominator which is 4
3/4 - 1/4 + 1/2 = 3 - 1 + 2 / 4
=4/4
= 1

The empirical rule may be used to determine the percentage of data values that must be within only one, two, and three standard deviations of the mean for data having a bell-shaped distribution.
The 68 95 99 rule, commonly referred to as the empirical rule in statistics, asserts that given normal distributions, 68% of observed data points will fall within one standard deviation from the mean, 95% will fall between two standard deviations, and 99.7% will happen within three standard deviations.
Fairly anticipate that your data will resemble a normal distribution, the empirical rule, the mean, as well as the standard deviation become even more beneficial. Determine probabilities and percentages for many events just by knowing these two statistics.
The term "empirical rule" derives from empirical research, which relies on measurements and observations of actual results rather than theory. In other words, the term "empirical" denotes a foundation in actuality.

The scale factor of the image is 1/4 or 0.25.
What is scale factor?
The ratio of the scale of an original thing to a new object that is a representation of it but of a different size is known as a scale factor (bigger or smaller).
To solve this question, use the coordinates of WX and W'X' as points of reference.
From the diagram, it can be obtained that -
W(-8,8) and X(8,0)
W'(-2,2) and X'(2,0)
First, calculate distance for WX -
Distance formula is -
d = √(x2-x1)^2+(y2-y1)^2
Distance for WX -
d1 = √(8+8)^2+(0-8)^2
d1 = √(16)^2+(-8)^2
d1 = √256+64
d1 = √320
d1 = 17.88
Distance for W'X' -
d2 = √(2+2)^2+(0-2)^2
d2 = √(4)^2+(-2)^2
d2 = √16+4
d2 = √20
The scale factor is then calculated using -
Scale = W'X'/WX
Scale = d2/d1
Substitute values of d1 and d2 -
Scale =√20/√320
Scale = √(20/320)
Scale = √1/16
Scale = 1/4
Therefore, the scale value is 0.25.

Suppose we have n+ positive training examples and n− negative training examples. Let C+ be the center of the positive examples and C− be the center of the negative examples, i.e., C+ = 1 n+ P i: yi=+1 xi and C− = 1 n− P i: yi=−1 xi . Consider a simple classifier called CLOSE that classifies a test example x by assigning it to the class whose center is closest. • Show that the decision boundary of the CLOSE classifier is a linear hyperplane of the form sign(w · x + b). Compute the values of w and b in terms of C+ and C−. • Recall that the weight vector can be written as a linear combination of all the training examples: w = Pn++n− i=1 αi · yi · xi . Compute the dual weights (α’s). How many of the training examples are support vectors?
To show that the decision boundary of the CLOSE classifier is a linear hyperplane, we need to show that it can be represented as sign(w · x + b), where w is the weight vector, b is the bias term, and sign is the sign function that outputs +1 or -1 depending on whether its argument is positive or negative.
Let x be a test example, and let d+ = ||x - C+|| be the distance from x to the center of the positive examples, and d- = ||x - C-|| be the distance from x to the center of the negative examples. The CLOSE classifier assigns x to the positive class if d+ < d-, and to the negative class otherwise. Equivalently, it assigns x to the positive class if
||x - C+\(||^2\) - ||x - C-\(||^2\) < 0.
Expanding the squares and simplifying, we get
(x · x - 2C+ · x + C+ · C+) - (x · x - 2C- · x + C- · C-) < 0,
which is equivalent to
2(w · x) + (C+ · C+ - C- · C-) - 2(w · (C+ - C-)) < 0,
where w = C+ - C- is the vector pointing from the center of the negative examples to the center of the positive examples. Rearranging, we get
w · x + b < 0,
where b = (C- · C-) - (C+ · C+) is a constant.
Thus, the decision boundary of the CLOSE classifier is a hyperplane defined by the equation w · x + b = 0, and the classifier assigns a test example x to the positive class if w · x + b > 0, and to the negative class otherwise.
To compute the values of w and b in terms of C+ and C-, we can use the definition of w and b above. We have
w = C+ - C-,
b = (C- · C-) - (C+ · C+).
To compute the dual weights α's, we need to solve the dual optimization problem for the support vector machine (SVM) with a linear kernel:
minimize 1/2 ||w||^2 subject to yi(w · xi + b) >= 1 for all i,
where yi is the class label of the i-th training example, and xi is its feature vector. The dual problem is
maximize Σi αi - 1/2 Σi Σj αi αj yi yj xi · xj subject to Σi αi yi = 0 and αi >= 0 for all i,
where αi is the dual weight corresponding to the i-th training example. The number of support vectors is the number of training examples with nonzero dual weights.
In our case, the training examples are the positive and negative centers C+ and C-, so we have n+ + n- = 2 training examples. The feature vectors are simply the centers themselves, so xi = C+ for i = 1 and xi = C- for i = 2. The class labels are yi = +1 for i = 1 (positive example) and yi = -1 for i = 2 (negative example). Plugging these into the dual problem, we get
maximize α1 - α2 - 1/2 α\(1^2\) d(C+, C+) - 2α1α2 d(C+, C-) - 1/2 α\(2^2\) d(C-, C-) subject to α1 - α2 = 0 and α1,

Answer: They played 25 games
Step-by-step explanation: If they had 15 wins and the total games they played is 60% then they lost 10 times and they played 25 games because if you divide 15 by 60 you get 0.25 so they played 25 games.
The general form of the solutions of the recurrnce relation with the following characteristic equation is:
(r-1)(r-4)=0
A. an=a1(1)n-a2(4)n
B. None of the above
C. an=a1(-1)n+a2(4)n
D. an=a1(-1)n+a2(-4)n
The characteristic equation for the recurrence relation is (r-1)(r-4)=0. This equation has two roots:
r=1 and r=4. Therefore, the general form of the solution is an = a1(1)n + a2(4)n. Therefore, the correct answer is A.
The recurrence relation can be written as an = an-1 + 4an-2. Substituting the general form of the solution into th
is equation, we get a1(1)n + a2(4)n = a1(1)n-1 + a2(4)n-1 + 4a1(1)n-2 + 4a2(4)n-2. Dividing both sides by 4n-2, we get (a1/4)(1)n-2 + a2(1)n-2 = (a1/4)(1)n-3 + a2(4)n-3 + a1(1)n-4 + a2(4)n-4. This equation holds for all n. Therefore, equating coefficients of like terms, we get a1/4 = a1/4, a2 = 4a2, a1 = a1/4, and a2 = 4a2. Solving these equations, we get a1 = a1/4 and a2 = 4a2.
Therfore, the general form of the solution is an = a1(1)n + a2(4)n.

The general form of the solutions of the recurring relation with the following characteristic equation is ( an=a1(1)n-a2(4)n.
The general form of the solutions of the recurrence relation with the characteristic equation (r-1)(r-4)=0 is a linear combination of the form an=a1(1)n+a2(4)n, where a1 and a2 are constants determined by the initial conditions of the recurrence relation.
This can be seen by factoring the characteristic equation into two linear factors: r-1=0 and r-4=0, which correspond to the two possible roots of the characteristic equation.
The solution to the recurrence relation is a linear combination of these two roots raised to the power of n, with the coefficients determined by the initial values of the sequence.
Therefore, the correct answer is A.
