Answer:

Option b (Port 22) seems to the appropriate choice.

Explanation:

<u>Below seem to be some measure you should take to correct this mistake.</u>

  • Verify whether Droplet's host IP address seems to be right.  
  • Verify existing connection supports communication over all the utilized SSH port. Any access points can be able to block port 22 and sometimes customized SSH. For illustration, you could do this by checking different hosts who used the same port, using only a recognized working SSH connection. These could help you identify unless the current problem is not particular to clients' Droplet.
  • Authenticate the Droplet configuration settings. Verify that they're not being configured to DROP 's preferred policy, and do not apply the port to require connectivity.

The SSH server also operates on port 22, by default.  

Other choices don't apply to the specified scenario. So that the argument presented above will be appropriate.

Ghella [55]

Answer:

The answer to this question is given below in the explanation section.

Explanation:

The correct answer to this question is an online decision support system. Because the decision support systems process the data, evaluate and predict the decision, and helps the decision-makers,  and offer real-time information immediately in making the decision in an organization. So the correct answer to this question is the decision supports system.

Why other options are not correct

Because the transaction processing system can only process the transaction and have not the capability to make the decision for the future. Office support processing system support office work, while the batch processing system process the task into the batch without user involvement.   however, online executive processing does not make decisions and offer timely information to decision-makers in an organization.

Svetllana [295]

Answer:

Big Oh notation is used to asymptotically bound the growth of running time above and below the constant factor.

Big Oh notation is used to describe time complexity, execution time of an algorithm.

Big Oh describes the worst case to describe time complexity.

For the equation; T(N) = 10000*N + 0.00001*N^3.

To calculate first of all discard all th constants.

And therefore; worst case is the O(N^3).

Choose the correct sequence for classifier building from the following.
Alekssandra [29.7K]

Answer:

b

Explanation:

First, we need to initialize the classifier.

Then, we are required to train the classifier.

The next step is to predict the target.

And finally, we need to evaluate the classifier model.

You will find different algorithms for solving the classification problem. Some of them are like  decision tree classification  etc.

However, you need to know how these classifier works.  And its explained before:

You need  to initialize the classifier at first.

All kinds of classifiers in the scikit-learn make use of the method fit(x,y) for fitting the model or the training for the given training set in level y.

The predict(x) returns the y which is the predicted label.And this is prediction.

For evaluating the classifier model- the score(x,y) gives back the certain score for a mentioned test data x as well as the test label y.
