Answer:
C) cluster analysis
Explanation:
Regression analysis. The regression analysis determines the relationship between the two variables. Thus, one of these quantities (X) is given in advance(dependent) and is not random. The second value (U) is the independent and random number. The randomness of the second quantity can be explained for two reasons. First: Measuring the random number U, which depends on the number X, is associated with certain errors; second: The value of U may depend on other uncontrollable factors, in addition to being dependent on the value of the corresponding X value. In this case, we need to talk about the distribution of the random variable U against each value of the X variable. The main purpose of the regression analysis is to build a mathematical model that takes into account the factors affecting the physical process using experimental data and evaluating its accuracy. The least squares method is used for statistical estimation of the mathematical model's suitability to experimental data.
Discriminant analysis is a method used in statistics, pattern recognition, and machine learning to find a linear combination of attributes that define or distinguish two or more classes or events. The resulting combination can be used as a linear classifier or more often to reduce the size before classifying. LDA is closely related to variance analysis (ANOVA) and regression analysis, which try to express a dependent variable as a linear combination of other properties or dimensions. However, while variance analysis uses qualitative independent variables and a continuous dependent variable, discriminant analysis has continuous independent variables and a qualitative dependent variable.
Cluster analysis or clustering is a problem of grouping a number of objects. In this problem, objects must be in some way more similar to those in other groups to accommodate the same clusters (clusters). One of the main problems with data transmission is a common technique used in statistical data analysis. It is also used in machine learning, pattern recognition, image analysis, data retrieval, bioinformatics, data compression and computer graphics.
One-way analysis of variance (ANOVA) is used to calculate the significance of the difference between three and more independent means in a normally distributed series. ANOVA compares the arithmetic means of three or more groups alone; ANOVA result is also significant when at least one of these comparisons is significant. To measure the significance it will have the relation to the regression analysis that's why there will be dependent and independent variables as well.
Answer:
The correct answer is letter "A": In the end you probably won't have the information you need to solve your original problem.
Explanation:
A typical problem researchers find at the end of their study is the lack of relevant information that could allow them to solve the reason for the research. The issue, in fact, relies on the sources the researches chose to conduct the study. However, that scenario could be beneficial since it will allow the researcher to have a better idea of the type of information necessary.
Answer:
The most you can pay for the pitcher is $17.32
Explanation:
A mark up is a percentage that is always applied on the cost to come up at a required gain over cost. The cost is always taken to be 100% when apply a mark up on cost.
If the mark up is of 27% and cost is 100% then a selling price of 22 will be equal to cost + markup.
Let cost be x.
Selling price = Cost + Mark up
22 = 100% * x + 27% * x
22 = 1x + 0.27x
22 = 1.27 x
22/1.27 = x
x = $17.3228 rounded off to $17.32
Answer:
The correct answers are letters "B" and "D".
Explanation:
The global service system of Theo Chocolate provides a great opportunity for some of its staff to get a <em>deeper insight into how the company's different markets work</em>. Operations in different regions include coping with different cultures which also include talking about different people and consumer patterns. Thus, all this information can be collected by the employees who are sent for one year to work in those regions.
Furthermore, chances of <em>diversification chances may appear in spotting the opportunities</em> of Theo Chocolate in foreign markets. The organization must ensure that the members sent for the exchange experience are well trained to get the most out of the global service program.
Answer:
Initial Velocity= 49 m/s
Time period= 5 secs
Explanation:
THIS IS THE COMPLETE QUESTION BELOW
A rocket shoots up 123 meters. What is it initial velocity?How long is it ascending
The initial velocity can be calculated using the expression below
u= √( 2gh)
Where g= Acceleration due to gravity= 98 m/s^2
h= height
Substitute the values we have
u = √(2*9.8*123)
u=√( 2410.8)
u = 49 m/s
the time period can be calculated as
(49/9.8)
= 5 sec
Hence time period is 5 secs
