Answer:

The options for this question are the following:

a. 1

b. 2

c. 0.5

d. 1.5

The correct answer is a. 1 .

Explanation:

Group analysis or grouping is the task of grouping a set of objects in such a way that the members of the same group (called a cluster) are more similar, in some sense or another. It is the main task of exploratory data mining and is a common technique in the analysis of statistical data. It is also used in multiple fields such as machine learning, pattern recognition, image analysis, information search and retrieval, bioinformatics, data compression and graphic computing.

Group analysis is not in itself a specific algorithm, but the task pending solution. Clustering can be done using several algorithms that differ significantly in your idea of ​​what constitutes a group and how to find them efficiently. Classical group ideas include small distances between members of the group, dense areas of the data space, intervals or particular statistical distributions. Clustering, therefore, can be formulated as a multi-objective optimization problem. The appropriate algorithm and the values ​​of the parameters (including values ​​such as the distance function to use, a density threshold or the number of expected groups) depend on the set of data analyzed and the use that will be given to the results. Grouping as such is not an automatic task, but an iterative process of data mining or interactive multi-objective optimization that involves trial and failure. It will often be necessary to pre-process the data and adjust the model parameters until the result has the desired properties.

The shape of your utility function implies that you are arisk-averse individual, and, therefore, youwould accept the wager becau
Furkat [3]

<u>Solution and Explanation:</u>

As the utility function is concave in shape, so person is risk averse.  Thus, he will not accept the gamvle.

The difference between utility at point A&C = 70 minus 65 = $5, is less than a the difference between A&B = 65 minus 55 = $10

<u>MCQ: </u>

Answer is option a&d  - risk averse people fear a lot for losing money, thus they overestimate the probability of loss

Since, shape of utility function is concave, hence the double derivative of utility with respect to wealth is negative, so utility falls at an decreasing rate , as wealth increases

dusya [7]

Answer:

The correct option is (C)

The value of a firm's final product is the selling price whereas value added refers to the addition of value to the raw material (intermediate products).

Explanation:

The term "value added" describes the enhancement a company gives to its product before offering it to the customer. It can be considered as an extra special feature added by a company to increase the value of a final product.

What interest rate (the nearest percent) must Charlie earn on a $362000 investment today so that he will have $1126000 after 10
Papessa [141]

Answer:

12%

Explanation:

A = P(1+r)^n

A (amount) = $1126000

P (principal) = $362000

n = 10 years

1126000 = 362000(1+r)^10

1126000/362000 = (1+r)^10

(1+r)^10 = 3.1

1+r = 3.1^0.1

1+r = 1.12

r = 1.12 - 1 = 0.12 = 12%
