It is easy to implement k-means lacks consistency

What is euclidean distance?

Euclidean distance is a measure of the straight-line distance between two points in Euclidean space. It is the most widely used method of measuring distance between two points, and is the basis for many other types of distance metrics. Euclidean distance is calculated as the square root of the sum of the squared differences between a pair of points. For example, the Euclidean distance between points (x1,y1) and (x2,y2) is given by the formula: √(x2-x1)2 + (y2-y1)2. Euclidean distance can be calculated in any number of dimensions, and is particularly useful when dealing with multidimensional data. It is often used in machine learning and data mining applications to measure the similarity between data points.

A database administrator wants to correlate pairs of rows from the same table. Which type of join should the database administrator use?

Answers

To construct two or more database  copies of the same table using a self-join, a table is linked to itself using a table alias. A join condition is then used to match the rows from the various copies of the table.

Which join may be used to link rows from two tables so that there is a match in every row in each table?

Data from both tables is retrieved using the INNER JOIN statement, which only returns records or rows with matching values.

Which of the following joins is used to return every row from every table when the join condition is met?

When the join condition is met, the MySQL INNER JOIN is utilised to return all rows from all tables.

It is relatively simple to multiplex four STS-12 signals into one ____ signal.
STS-8
STS-16
STS-32
STS-48

Answers

STS-48. In telecommunications, multiplexing is the process of combining multiple signals into a single signal. In this case, the question asks about multiplexing four STS-12 signals. STS-12 is a standard transmission rate that carries 622 Mbps (megabits per second) of data.

To multiplex four STS-12 signals, we need to combine them into a single signal that carries four times the data rate, which is 2.488 Gbps (gigabits per second). Now, we need to identify which of the given options can carry this data rate. STS-8 carries 522 Mbps, which is not enough to carry the combined data of four STS-12 signals. STS-16 carries 1.244 Gbps, which is also not enough to carry the combined data. STS-32 carries 2.488 Gbps, which is enough to carry the combined data. However, the question asks for a relatively simple method of multiplexing, and STS-32 is a complex and expensive method. Therefore, the correct answer is STS-48, which carries a data rate of 4.976 Gbps, which is more than enough to carry the combined data of four STS-12 signals. Multiplexing four STS-12 signals into one STS-48 signal is a relatively simple and cost-effective method that is commonly used in telecommunications.

Answers

Note that chris will have to concentrate on investing majorly in stocks and mutual funds as they yield high rate but at high risk level too.

Why is this so?

To boost the growth potential of Chris' investment, he will need to put a greater proportion of his money in high yield portfolios. As a result, a potential high growth portfolio allocation may be considered.

Stock = 50%Mutual Fund = 35%Bond = 10%Savings = 5%

In other to build a potentially high growth portfolio, then Chris's focus would have be more on investment with higher rates and thus will have to take high risks.

Savings and Bonds would take up the lowest percentage as they have lower risk but also low return on investment.
