Which of the following is required by k-means clustering ? a. defined distance metric b. number of clusters c. initial guess of
mestny [16]

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.

You work for a landscape company that just got a contract to re-mulch a park. The area that needs mulching is 30 feet by 60 feet
morpeh [17]

Answer:

It cost $36 to the consumer just in materials to re-mulch the area

The dairy produce 8192 cups on average a day

Step-by-step explanation:

Dimensions of area that is needed to be mulch 30 feet by 60 feet.

1 foot = 0.333333 yards

Length = 30 feet = 9.99999 yards

Width = 60 feet = 19.99998 yards

Since we are given that They want a 3 inch layer of much on the area.

1 inch =0.0277778 yards

3 inch = 0.0833334 yards

So, the volume of mulch required for the given area :

=  length * width* thickness

= 9.99999*19.99998 *0.0833334

= 16.6666466667 cubic yards

Now 2 cubic yards can be covered with 1 bag of mulch

So, 16.6666466667 cubic yards can be covered with bags of mulch :

= \frac{16.6666466667}{2}

= 8.33332333335

Thus 9 bags are required to re mulch .

Since cost of 1 bag is $4.00

So, cost of 9 bags = 9*4 =$36

Hence it cost $36 to the consumer just in materials to re-mulch the area

Now,

The dairy produces 512 gallons of milk on average a day.

Now 1 gallon = 16 cups

So, 512 gallons = 512*16 = 8192 cups .

Hence the dairy produce 8192 cups on average a day

Could you please help me with this? It’s a problem from my grandson’s homework.
gulaghasi [49]

SOLUTION

From the question given, the cost of the toy truck is $36.50 before tax.

Now, the store selling the toy truck adds a 6% sales tax. This means

\begin{gathered} 6\%\times36.50 \\ =\frac{6}{100}\times36.50 \\ =\frac{6\times36.50}{100} \\ =\frac{219}{100} \\ =2.19\text{ dollars} \end{gathered}

Now, we will add this $2.19 to the initial cost, we have

2.19+36.50=38.69

This gives $38.69.

Finally we will do a discount of 10%. 10% discount is

\begin{gathered} 10\%\times38.69 \\ \frac{10}{100}\times38.69 \\ =\frac{10\times38.69}{100} \\ =\frac{386.9}{100} \\ =3.869 \end{gathered}

We will then subtract this 3.869 from 38.69, we get

\begin{gathered} 38.69-3.869 \\ =34.821 \end{gathered}

That is 34.821. The 1 which is the last number at the decimal part is less than 5, so we ignore it and our answer becomes $34.82
