The answer is D. All of the above.
The computational complexity of K-NN increases as the size of the training data set increase and the algorithm gets significantly slower as the number of examples and independent variables increase.
Also, K-NN is a non-parametric machine learning algorithm and as such makes no assumption about the functional form of the problem at hand.
The algorithm works better with data of the same scale, hence normalizing the data prior to applying the algorithm is recommended.
The answer is 41 degrees
180 - 139 degrees = 41 degrees
Answer:
9, 15, 21, 27
Step-by-step explanation:
Given n=6n+3
When n=1, t= 6(1)+3 =9
When n=2, t=6(2)+3=15
When n=3, t=6(3)+3=21
When n=4, t=6(4)+3=27
SHORT TRICK :
Whenever the value of 'n' is given in the form of an algebraic expression the common difference of the Arithmetic Progrsiion (A.P) is the coefficient of 'n' in the given expression.
Ex: In this Problem,
Given that n=6n+3
The coeeficient of 'n' is '6'
If you obsereve the answer you will also see that the Common difference is also '6'
X = 4 y = - 3
Substitute x for 4 and y for - 3
<u>x² - 4y
</u> 2
<u>4² - 4 *(- 3</u><u>)
</u> 2
<u>16 - ( - 12 )</u>
2
<u>16 + 12</u>
2
<u>28</u> = 14
2
Solution: 14
