Answer:

Explanation:

Depending on the software that Raj was using to create his project he should first see if the software itself saved the project. Usually many software such as those included in the Microsoft Office Suite save the file automatically every 5 minutes or so in case of a power outage or abrupt closure of the file. If this is not the case he should try and do a system restore with the unlikely hope that it restores an older version of his project.

solong [7]

Answer:

Explanation:

K- is the working procedure:

It takes n no. of predefined cluster as input and data points.

It also randomly initiate n centers of the clusters.

In this case the initial centers are given.

Steps you can follow

Step 1. Find distance of each data points from each centers.

Step 2. Assign each data point to the cluster with whose center is nearest to this data point.

Step 3. After assigning all data points calculate center of the cluster by taking mean of data points in cluster.

repeat above steps until the center in previous iteration and next iteration become same.

A1(4,8), A2(2, 4), A3(1, 7), B1(5, 4), B2(5,7), B3(6, 6), C1(3, 7), C2(7,8)

Centers are X1=A1, X2=B1, X3=C1

A1 will be assigned to cluster1, B1 will be assigned to cluster2 ,C1 will be assigned to cluster3.

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.

balandron [24]

Answer:

Bank or Wire transfers and ATM cash withdrawls

Explanation:

With P2P solutions like PayPal and Venmo there is far less reason to ever handle cash, especially from one person to another.

You’re trying to cast a video presentation from your tablet to a projector for a training session with some new hires. Although
Vikki [24]

Answer:

Troubleshooting steps to take:

  1. Restart the tablet
  2. Restart the projector

Explanation:

When such problems occur, the basic and quick troubleshooting step is to restart the device or devices involved.

  1. Restart the tablet: This could come in handy regarding this problem. The inability to connect to the projector could be due to the inability of a specific service or driver needed for the projector. Restarting the tablet will load up the drivers and services again to enable smooth connections. When a restart is done, bugs are fixed, internet connection is rectified, memory leaks are stopped, performance is aided, the RAM (Random Access Memory) is flushed or cleaned. This should resolve the problem, however, if not, try number 2.
  2. Restart the projector: There are driver software on projectors, and due to one system failure or another, these software may fail to load. This could affect its connection to another device. As done in (1), restarting the projector will fix those bugs and load up, which should solve the connection issue.
