RELATIONS AND FUNCTIONS
Q1. If (x/3 + 1, y - 2/3) = (5/3, 1/3), find the values of x and y.
Answer: Since ordered pairs are equal,
∴ x/3 + 1 = 5/3
⇒ x/3 = 5/3 - 1 = 2/3
⇒ x = 2
y - 2/3 = 1/3
y = 1/3 + 2/3
y = 3/3 = 1
Thus, x = 2 and y = 1
Understanding the central measures of tendency—mean, median, and mode—is a key part of learning statistics in Class 10 Mathematics. These measures help us summarise and analyse data by identifying the central or typical value in a dataset. Whether you're calculating the average score of a cricket match, finding the most common number in a list, or determining the middle value in a set of numbers, these concepts are incredibly useful in everyday life. To help you practise and master these ideas, we’ve put together a list of very short answer-based questions. These questions are designed to test your understanding and improve your problem-solving skills quickly and engagingly. Let’s dive in and explore the world of central measures of tendency!
Q1: If the value of each observation in the data is increased by 2, then the median of the new data __________

About the title "Virtually True"
The phrase "Virtually True" is an example of an oxymoron, a literary device that combines two contradictory or opposite terms to create a paradoxical effect. In this case, "virtually" suggests something that is almost or nearly true, while "true" implies absolute truth. The juxtaposition of these words creates a thought-provoking or ironic effect, often used to highlight complexity or ambiguity in a situation.

"I am heading back to my forest home,
Circled by rice fields green:"
The cobra dreams of returning to its natural home in the forest, surrounded by lush green rice fields. It yearns for the freedom it once had.

Machine learning focuses on selecting the right features to create effective models for specific tasks. Machine learning helps us create models that solve specific tasks by learning from data. To build effective models, it is important to select the right features (important pieces of information from the data).
