The answer is A because a system is actually made up of different parts working together as one unit. A phone is an example of a system because it is made up of parts that work together such as the processer and graphics card.

Which method of analysis does not classify variables as dependent or independent.
Olin [163]

The method of analysis does not classify variables as dependent or independent is cluster analysis.

Cluster analysis is a method that is used to process data in statistics. In cluster analysis, data is classified into groups based on similar characteristics the data share. For example, if cluster analysis is used to group students, students may be divided into clusters based on their gender or class.

An independent variable is the variable that is manipulated by the researcher. It is the variable that is tested to determine its effect on the dependent variable.

The dependent variable is the variable that is being measured in an experiment.

If 384 ft of fencing is available and the maximum area is desired, what will be the dimensions of the larger, outer rectangle? (
DIA [1.3K]

The dimensions of the smaller holding pens from the parameters given are; 96 ft and 31 ft

<h3>What dimensions will maximize the area?</h3>

From the complete question, if the side lengths of the big rectangle are x and y, then the expression for the area A is:

A = x*y

Then perimeter since we have 384 ft of fencing available is;

2x + 2y = 384  

y = (384 - 2x)/2

y = 192 - x

Put 192 - x for y in area formula;

A = x(192 - x)

A = 192x - x²

Completing the square of this are equation gives;

A = 9216 - (x - 96)²

This means that A is maximum at x - 96 = 0

Thus, A is maximum when x = 96 ft

At A_max; y = 192 - 96 = 96 ft

Since the area of the bigger rectangle has been maximized, it means that we have also maximized the area of the smaller pens. Therefore its' dimensions will be;

x_small = 96 ft/3 = 31 ft

y_small = 96 ft
