A mile is an imperial unit of measurement commonly used in the United States to determine the distance between two locations. Kilometers are used to measure the same thing but are metric units. To convert kilometers to miles or vice versa you only need a mathematical formula that is quite easy to use.

With Spearman's rank correlation coefficient we can identify whether two variables have a monotonic function relation (that is, when one number increases, the other number will also increase, or vice versa). To calculate Spearman's rank correlation coefficient, you need to rank and compare data sets to find d 2 , and then enter the data into the standard or simplified Spearman rank correlation coefficient formula.

This is an article on how to factor a cube polynomial. We'll explore how to factor using groupings as well as using factors from independent terms. Step Method 1 of 2: Factoring by Grouping Step 1. Group the polynomial into two parts Grouping a polynomial into two halves will allow you to break each part separately.

To calculate the area of a triangle, you need to know its height. If this data is unknown in the problem, you can easily calculate it based on the known data. This article will guide you through finding the height of a triangle using three different methods, based on known data.

The P value is a statistical measurement that helps scientists determine if their hypothesis is correct. The P value is used to determine if the results of their experiment are within the range of values that are normal for the things being studied.

Confused about converting minutes into time? Do not worry! You can do this in just a few ways. Dividing the number of minutes by 60 will equal the time in hours, because there are 60 minutes in an hour. Step Method 1 of 2: Convert Minutes to Time Step 1.

A rational equation is a fraction with one or more variables in the numerator or denominator. A rational equation is any fraction that involves at least one rational equation. Like ordinary algebraic equations, rational equations are solved by performing the same operation on both sides of the equation until the variables can be transferred to either side of the equation.

In derived calculus, an inflection point is the point on a curve at which the curve changes sign (from positive to negative or from negative to positive). It is used in a variety of subjects, including engineering, economics, and statistics, to determine fundamental changes in data.

Reading the numbers MMDCCLXVII was not difficult for the ancient Romans or for the many medieval Europeans who continued to use the Roman system. Learn how to read roman numerals by following a few basic rules. Step Method 1 of 3: Reading Roman Numerals Step 1.

A trinomial is an algebraic expression consisting of three terms. Most likely, you will begin to learn how to factor a quadratic trinomial, meaning a trinomial written in the form ax 2 + bx + c. There are a few tricks to learn, which can be used for many different types of quadratic trinomials, but you'll be able to use them better and faster with practice.

Trying to read a string of binary 1's and 0's seems like a tough job. However, with a little logic, we can figure out what it means. Humans have adapted to using the base ten number system simply because we have ten fingers. On the other hand, computers only have two “fingers” – on and off, on and off, or zeros and ones.

In a “system of equations”, you are asked to solve two or more equations simultaneously. When the two equations have two different variables, for example x and y, the solution may seem difficult at first. Luckily, once you know what you need to do, you can simply use your algebraic skills (and the science of calculating fractions) to solve the problem.

Area is a measure of an area bounded by a two-dimensional shape. Sometimes the area can be found simply by multiplying two numbers, however, it often requires more complicated calculations. Read this article for a brief explanation of the areas of quadrilaterals, triangles, circles, pyramidal and cylindrical surfaces, and the area under curved lines.

A cylinder is a simple geometric shape with two circular bases of equal size and parallel. To calculate the volume of a cylinder, you have to find the height (h), the radius (r), and calculate it in a simple formula: V = hπr 2 . Here's how to do it.

The meter is a unit of length in the measurement system. This unit is the basic unit of length in the International System of Units. Miles are used in the United States to measure length. If you memorize the formula, how to calculate it is very easy.

There are various ways to do the division. You can divide decimals, fractions, or even exponents, and use long or short division. If you want to know the different ways of dividing numbers, follow the steps below. Step Method 1 of 5:

"Cubication" is a way of measuring volume in shipping or buying goods in bulk. The cubication determines how large the volume, or space in three dimensions, of a chest of goods when placed in a warehouse. Cubications can be calculated in cubic feet or cubic meters.

Perimeter is the length of all the outermost lines of the polygon, while area is the amount of space that fills the side. Area and perimeter are useful quantities that can be used in household projects, building projects, DIY projects (do-it-yourself or DIY), and estimates of materials that may be needed.

In studying optical instruments, the "magnification" of a lens-like object is the ratio of the height of the image you see to the actual height of the object. For example, a lens that can make an object look very large has a "

In this article, we will discuss how to solve a two-variable system of linear equations. What is a two-variable system of linear equations? So, if there are two or more linear equations of two variables that have a relationship with each other and have one solution, it is called SPLDV.

There are two types of rulers: the English ruler or fractional ruler, and the Metric ruler or decimal ruler. Reading this ruler may seem complicated at first glance because of the many small lines on the line, but actually reading a ruler is quite simple.

Mathematics is actually one of the subjects that have the most enemies, both at the school and university levels. That's why, most of the people have great worries before math exams arrive. Fortunately, there are many techniques that you can use to make your exam situation easier, some of which are reading the instructions on the questions well, writing down all the necessary formulas, reading all the questions carefully and carefully, and writing the answers neatly to make it

The half-life of a compound's decay is the time it takes for it to shrink by half. Initially, half-life was used to describe the decay of radioactive elements such as uranium or plutonium, but it can be used for any compound that decays at an exponential rate.

Learning how to simplify algebraic expressions is one of the keys to mastering basic algebra and the most useful tool any mathematician needs to have. Simplification allows mathematicians to convert complex, long, and/or odd expressions into simpler or easier equivalent expressions.

In statistics, the mode is the number that appears most often in a set of numbers or data. the data itself does not always have only one mode, it can be two or more (so it is called bimodal or multimodal). In other words, all the numbers that occur most often in a data can be called the mode.

Although precision and accuracy are often used interchangeably, they are actually very different words in math and science. Precision means that a measurement has nearly the same value each time it is made. For example, if you step on the scale 5 times in a row, a scale that has good precision will show the same mass each time.

Have you ever wanted to know how to convert cm to inches? Follow the steps in this article to become a conversion master. You may be surprised at how often this knowledge will come in handy. Step Step 1. Know the difference between centimeters and inches Centimeters (cm.

A protractor is a tool used to measure as well as draw angles. This tool is usually semicircular, but a full-circle 360-degree version is also available. If looking at this tool really leaves you confused, never fear; Learning to use this tool is relatively easy.

Integral in calculus is the opposite of differentiation. Integral is the process of calculating the area under a curve bounded by xy. There are several integral rules, depending on the type of polynomial present. Step Method 1 of 2:

In statistics, range is the difference between the highest value in a data set and the lowest value in a data set. Range shows how spread out the values are in a series. If the range is a large number, then the values in the series are highly dispersed;

A millimeter is a unit of length that is part of the standard measure in the metric system. One millimeter is equal to 1/1,000 of a meter. There are several ways to calculate millimeters. The easiest and simplest way is to use a metric ruler, which is already labeled with millimeter markers.

The process of determining the squared inch (written as in 2 ) in all areas of two-dimensional figures are usually quite simple. For the simplest case, when the figure is a square or quadrilateral, the area in inches squared can be obtained using the formula length × width .

The meter is a unit of length in the metric system. The meter belongs to the International System of Units (SI). Most countries around the world use the metric system (except the United States, Liberia, and Myanmar). If you live in a country that doesn't use the metric system, you may need to learn how to convert yards to meters.

The geometric mean is another way of finding the average value of a set of numbers, which is done by multiplying the values before taking the roots, instead of adding up the values and dividing them as in an arithmetic mean. Geometric averages can be used to calculate the average rate of return in financial analysis or indicate the growth rate of something over a period of time.

In statistics, the range of a data set is known as the difference between its largest and smallest values. All you have to do to find it is to arrange the set of numbers from smallest to largest and subtract the smallest value from the largest value.

Each function has two variables, namely the independent variable and the dependent variable. Literally the value of the dependent variable "depends" on the independent variable. For example, in the function y = f(x) = 2 x + y, x is the independent variable and y is the dependent variable (in other words, y is a function of x).

IQR is the interquartile range or the quartile root range of a data set. IQR is used in statistical analysis to help draw conclusions about a data set. IQR is used more often than range because IQR does not include the outermost data. Continue reading to learn how to find the IQR!

Calculating the area of a polygon can be as simple as finding the area of a regular triangle or as complex as finding the area of eight irregular areas. If you want to know how to find the area of a polygon, follow these steps: Step Method 1 of 3:

The easiest way to measure angles is to use a protractor. However, if this is not available, you can determine the size of the angle using simple triangular geometry principles. To do this, you'll need a science calculator. Most smartphones come with this calculator, but if you don't have one, you can also download a free calculator app or use an online calculator.

A vernier caliper is a tool used to measure the dimensions of an object's inside or outside, and also to measure depth (holes, gaps, etc.). This tool allows you to get more precise measurement results than you would get with a regular ruler/tape.
