According to Jean Piaget, in what stage of cognitive development does the individual apply the tools of abstract thinking?  

A machine learning model is a function that seeks to identify the relationship between the features and the target variable.

Machine Learning (ML) is a method that allows machines to replicate human behavior.

In supervised learning, the machine learning algorithm learns from labeled data.

What type of figure is represented in the ML model?

Reinforcement learning is a domain of machine learning focused on how intelligent agents perform actions within an environment to optimize rewards. 

Execute Hierarchical Clustering using Machine Learning for the provided x and y data. x = [4, 5, 10, 4, 3, 12, 15, 7, 17, 19]y = [21, 25, 23, 14, 17, 28, 20, 17, 15, 24] Kindly upload all generated data along with your code.  

In a machine learning model, what is the classification of the following figure:

In this inquiry, you are required to employ KNN to ascertain the value of [5.36] as true or false (0 or 1) based on the provided datasets x and y. X = [[0], [1], [2], [3], [4], [5], [6]]y = [0, 0, 1, 1, 0, 1, 0] Kindly upload all generated data along with your code.
