Which statement best describes the function?

Mathematics

Answer:

A.) The function is Nonlinear

Step-by-step explanation:

a function is a bunch of ordered pairs of things (in our case the things will be numbers, but they can be otherwise), with the property that the first members of the pairs are all different from one another. A function is an equation that has only one answer for y for every x. A function assigns exactly one output to each input of a specified type. It is common to name a function either f(x) or g(x) instead of y. f(2) means that we should find the value of our function when x equals 2. Functions are used because of following reasons – a) To improve the readability of code. b) Improves the reusability of the code, same function can be used in any program rather than writing the same code from scratch. c) Debugging of the code would be easier if you use functions, as errors are easy to be traced. In mathematics and science, a nonlinear system is a system in which the change of the output is not proportional to the change of the input. Nonlinear problems are of interest to engineers, biologists, physicists, mathematicians, and many other scientists because most systems are inherently nonlinear in nature. Material nonlinearity involves the nonlinear behavior of a material based on a current deformation, deformation history, rate of deformation, temperature, pressure, and so on. Examples of nonlinear material models are large strain (visco) elasto-plasticity and hyperelasticity (rubber and plastic materials). also nonlinear. adjective. If you describe something as non-linear, you mean that it does not progress or develop smoothly from one stage to the next in a logical way. Instead, it makes sudden changes, or seems to develop in different directions at the same time.

Example: Solve the linear equation 3x+9 = 2x + 18.

Example: Solve the nonlinear equation x+2y = 1 and x = y.

1. [5 pt.] For each of the following variables about students in RBS, determine whether the variable is categorical or numerical
Ksju [112]

Answer:

(a) <u>City where a student was born </u>

Categorical nominal scale

(b) <u>Absolute distance between a student’s home and a stat. classroom </u>

Numerical ratio scale

(c) <u>Current account balance of a student’s checking bank account (considering debt/loan) </u>

Numerical ratio scale

(d) <u>Number of credit cards that a student has </u>

Numerical discrete interval scale

(e) <u>Floor level on which a student spent time the most during the last semester </u>

Categorical ordinal scale

Step-by-step explanation:

Let's recall the concepts first:

<h3>Categorical variable </h3>

Is a variable that can take one value from a limited set of choices, for example “blood type (A+, AB-,etc)”, “hair color (black, red, etc)”, “country of origin”, “level of instruction (elementary, high school, college, etc)”  

  • <em><u>The categorical variable is measured in a nominal scale</u></em> if there is no intrinsic order in the variable, for example if the variable is “gender”, there is no intrinsic reason to think that “male” comes before “female” or vice versa.  
  • <em><u>The categorical variable is measured in an ordinal scale</u></em> if there is some intrinsic order in the values. For example if the variable is “level of instruction” we can order it from less to high (elementary, high school, college graduate, masters degree, PhD degree) or from high to low.
<h3>Numerical variable </h3>

As the name suggests is a variable that can take numerical values, for example “height”, “weight”, “number of people who smoke in Minnesota”

  • <em><u>The numerical variable is discrete</u></em> if it only takes inter values, for example “number of flights that land to JFK airport every day”
  • <em><u>The numerical variable is continuous</u></em> if it can take either integer or non integer values, for example “distance between to points in the plane”
  • <em><u>The numerical variable is measured in an interval scale</u></em> if we can determine both the order and difference between the two numbers but the ratio of the values is meaningless. For example if the variable is “year of birth” 1957 and 2001 would be two instances of the variable but 1957/2001 or 2001/1957 are meaningless.  
  • <em><u>The numerical variable is measured in a ratio scale</u></em> if we can determine both the order and difference between the two numbers and the ratio of the values is meaningful. For example if you have two salaries, let's say A=$60,500 and B=$90,750, the ratio 90,750/60,500 =1.5 is meaningful because is telling us that salary B is 50% greater than A.

Once we have these concepts clear, we can determine the type of variable of the problem

(a) <em>City where a student was born </em>

Categorical nominal scale

(b) <em>Absolute distance between a student’s home and a stat. classroom </em>

<em>Numerical ratio scale </em>

(c) <em>Current account balance of a student’s checking bank account (considering debt/loan) </em>

Numerical ratio scale

(d) <em>Number of credit cards that a student has </em>

Numerical discrete interval scale

(e)<em> Floor level on which a student spent time the most during the last semester </em>

Categorical ordinal scale
