Data Mining Techniques

Identification of whether the task required supervised or unsupervised learning:

a. supervised learning

b. supervised learning

c. supervised learning

d. supervised learning

e. supervised learning

f. unsupervised learning

g. unsupervised learning

h. supervised learning

Explanation:

There are supervised and unsupervised machine learning models.  In a supervised learning model, the algorithm evaluates a labeled dataset by comparing it with another dataset called the training data.  The purpose is to evaluate its accuracy on the training data. On the other hand, an unsupervised model uses the unlabeled dataset and tries to make sense of it by extracting non-existing features and patterns without the training dataset.

Dmitriy789 [7]

Answer:

The answer is: $29,000

Explanation:

To calculate Job A3B's costs during September we must add direct materials plus 3 times direct labor:

September costs = direct materials + (direct labor x 3) = $1,500 + $9,000

September costs = $10,500

We do the same for October:

October costs: direct materials + (direct labor x 3) = $2,000 + $16,500

October costs = $18,500

The total cost for Job A3B is: $10,500 + $18,500 = $29,000
