What is Clustering method in unsupervised learning?
An method known as unsupervised learning discovers patterns in untagged data. The idea is to compel the computer to create a clear representation of its surroundings and then produce innovative material from it through imitation, which is a crucial learning method for people.
There are several ways to evaluate the performance of a clustering method in unsupervised learning. Some common evaluation metrics include:
The sum of distances between objects in the same cluster (also known as the intra-cluster distance): This measure indicates how closely the objects in each cluster are related to each other. A good clustering method will have a low intra-cluster distance, indicating that the objects within each cluster are similar to each other.The distances between different clusters (also known as the inter-cluster distance): This measure indicates how distinct the different clusters are from each other. A good clustering method will have a high inter-cluster distance, indicating that the clusters are well separated from each other.The predicted labels are equal to the actual labels: This measure is only applicable if you have labeled data and you are using the clustering method to classify the data into different categories. If the predicted labels are equal to the actual labels, it means that the clustering method is correctly identifying the different categories.The SVM accuracy on the data: This measure is only applicable if you are using a support vector machine (SVM) as a classifier after the clustering step. The SVM accuracy indicates how well the SVM is able to classify the data based on the clusters produced by the clustering method. A good clustering method will result in high SVM accuracy.To know more about Clustering method in unsupervised learning visit,

Decide whether QRST and you UVWX are similar.
Answer:
no
Step-by-step explanation:
Answer:
They are not similar.
Step-by-step explanation:
Let's compare 2 sides of QRST and the 2 corresponding sides in UVWX, and set up a side length ratio.
20/19 = 15/7. If these ratios are equal the shapes are similar, but the ratios obviously aren't.
Sooo....the shapes aren't similar.

Write the equation of each circle. center at (-4, 3), radius 9
Answer:
(x-h)²+(y-k)²=r²
putting respective value
(x--4)²+(y-3)²=9²
(x+4)²+(y-3)²=81
Answer:
(x + 4)^2 + (y - 3)^2 = 9^2
Step-by-step explanation:
Here our center is at (-4, 3), so h = -4 and k = 3. Radius, r, is 9.
Insert these values into the standard equation of a circle centered at (h, k) with radius r:
(x - h)^2 + (y - k)^2 = r^2 becomes:
(x + 4)^2 + (y - 3)^2 = 9^2

Issac shovels driveways to earn money. He can shovel 14 driveways in 8 hours. Earns $25.00 for each driveway. Issac is saving up to buy a new computer that costs $831.25. How many hours does Issac need to work to earn enough money to purchase the computer?
Answer:
19 hours
Step-by-step explanation:
Issac shovels driveways to earn money. He can shovel 14 driveways in 8 hours. Earns $25.00 for each driveway. Issac is saving up to buy a new computer that costs $831.25. How many hours does Issac need to work to earn enough money to purchase the computer?
Step 1 find the number of driveways to shovel
25x = $831.25
x = $831.25/25
= 33.25 driveways
Step 2
He can shovel
14 driveways = 8 hours
33.25 driveways = x
Cross Multiply
14x = 8 × 33.25
x = 8 × 33.25/14
x = 19 hours

A squirrel burrowed 12 holes in 3 minutes. How many holes could the squirrel burrow in 12 minutes?
Answer:
48 holes
Step-by-step explanation:
We know that in 3 minutes, a squirrel managed to bury 12 holes. Now, what if there were 12 minutes?
To solve this, we need to see the increase in minutes and implement the same thing to the holes.
So how do we get 3 minutes to 12 minutes? By multiplying 3 by 4, now do the same for the amount of holes the squirrel burrowed in 3 minutes.
3min * 4 = 12min
12 holes * 4 = 48 holes
