<span>Her survey will be both a representative and a random sample. The sample is random since the students are randomly chosen by the professor's computer program and each student has an equal chance of being chosen. The survey is representative since the student chosen will represent the whole class.</span>

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.
Elastic.
This is
the formula for elasticity:
Elasticity
= (Quantity variation/Quantity)/(Price variation/Price)
Inelastic
demand is the one in which a variation in price doesn’t lead to an important
variation in the quantity bought by consumers. So, in the formula, numerator is
much smaller than denominator, so the fraction is lower than 1. That happens
with necessary goods (typically, food).
On the
contrary, elastic demand is the one in which a variation in the price leads to
an important variation in the quantity bought by consumers, and that means the
fraction is higher than 1. So if I sell the product at a lower price, I will
sell much more product.
Considering the formula:
R = P*Q, when demand is elastic,
I will
have much more sold quantity with just a little lower price, which leads to a higher
revenue.

Answer:
A. capitalize capitalize
Explanation:
All the expenses incurred to make the asset usable are capitalized and those expenses become the part of cost of that assets for which that are incurred. Interest on debt to purchase an asset and in case to construct the asset both are capitalized, because these expenses are essential to make assets usable for the business.
