centroids d. all of the above
Mathematics
1 answer:
mestny [16]3 years ago

Answer:

d. all of the above

Step-by-step explanation:

K-means clustering is a term used to describe a technique of vector quantization, that attempts to partition "n" observations into "k" clusters whereby each observation refers to the cluster with the closest mean which represents a model of the cluster.

This implies that the K-means algorithm recognizes the "k" number of centroids, and then assigns every data point to the closest cluster while the centroids remain as small as possible.

Hence, the following is required of K-means clustering:

1. defined distance metric

2. number of clusters

3. initial guess of centroids

Therefore, in this case, the correct answer is option D: All of the above.

80 yards * 2 + 60 yards * 2 = 160 + 120 = 280 yards

The correct measurement would be A. yards.

Welcome to Brainly!

5(n-2) = 2+5n + 2n fits your equation.  After multiplication, we have

5x - 10 = 2 + 7n

Combining like terms, we get:

-12 = 2n, so that n = -6.

AysviL [449]

Answer:

6

Step-by-step explanation:

You have a total of $30, but you can't spend it all on buckets of balls because first you have to pay the fee to attend the golf clinic.

So you have to figure out how much you have left after you spend $12 on fees.

$30−$12=$18

This means that you can spend $18 on buckets of golf balls.

At $3 each, how many buckets can you buy with $18?

18÷3=6

This means that you can buy

<u>6</u> buckets of golf balls at the clinic after paying the fee to join.

Equation:

12+3x=30

3x=18

x=6
