Answer:

b. Prototype-based

Explanation:

In clustering, certain methods are used to identify groups. This identifies groups of similar objects in a multivariate sets of data which is collected from different fields.

Shared-property clusters shares some property.

Hierarchical cluster builds a hierarchy.

Density-based identifies clusters in a data. While the prototype based sents observation to nearest prototype.

Why was the movable type of the printing press such a breakthrough for publishing?

guapka [62]

Movable type is not part of a printing press. Before movable type and printing presses, things had to be manually transcribed (copied by hand), which was extremely expensive. The press mechanized copying, lowering it's cost and driving down the cost of reproduction.

Arguably, there wasn't any publishing before movable type and printing presses.

How efficient would a 6-bit code be in asynchronous transmission if it had 1 parity bit, 1 start bit, and 2 stop bits?

How efficient well if we are transmitting 6bits and we need 10 to transmit the 6 bits that would be 6/10 = .6 = 60% efficient.

Meg[] elements = {new Lois(), new Stewie(), new Meg(), new Brian()}; for (int i =0; i

Stells [14]

Complete question is attached as snapshot.

Answer:

This will result in a compilation error.

Here's the inheritance hierarchy:

Meg -> Lois -> Brian -> Stewie

Now Meg has 2 public Fxns, a() and toString().

Lois inherits from Meg and all its public functions as well but, overrides the a() fxn of its super class.

So finally Lois has fxns a(), b() and toString().

Brian extends Lois and inherits all the above listed fxns of Lois, but overrides the b() and toString() fxns.

Stewie extends Brian and inherits all the fxns of Brian, but overrides the a() and toString() fxns.

In the Main driver fxn, we call a() and b() methods of all these classes but, the base class Meg has no b() and it is not extending any class so its not available in its scope.

This results in a compilation error.
