This article will tell you how to convert the binary system (base 2) to the hexadecimal system (base 16). Since both bases are multiples of 2, this procedure is much easier than other more general ways of converting that you will find online.

A mathematical function (usually expressed as f (x)) can be interpreted as a formula that allows you to derive the value of y based on a given value of x. The inverse function of f (x) (which is expressed as f -1 (x)) is in practice the opposite procedure, thanks to which the value of x is obtained once that of y has been entered.

Do you need to convert a hexadecimal number into a form that is more understandable to you or your computer? Converting a hexadecimal number to binary is a very simple process, which is why the base 16 numbering system has been adopted by some programming languages.

To multiply fractions, all you have to do is multiply the numerators and denominators together and then simplify the result. To divide them, instead, you just have to flip one of the two fractions, multiply and finally simplify. If you want to learn how to do this in a flash, read on.

For many, reading the phrase "Calculating the rate of growth" can bring to mind a very complex and intimidating mathematical process. In reality, calculating the growth rate is a very simple operation. The base growth rate is simply given by the difference between two values over time and is expressed as a percentage of the first data taken into consideration.

After collecting data, one of the first things to do is analyze it. This usually means finding its mean, standard deviation, and standard error. This article will show you how. Steps Method 1 of 4: The data Step 1. Get a series of numbers to analyze This information is referred to as a sample.

Many countries adopt the unit of measurement of degrees Celsius for atmospheric temperature. There are several online applications that can convert the temperature expressed in degrees Celsius exactly to degrees Fahrenheit, but you may not have access to the internet:

A pentagon is a polygon with five sides. Almost all of the mathematical problems you will have to face in your school career study regular pentagons, therefore composed of five identical sides. To calculate the area of this geometric figure there are two methods that will be used on the basis of the information available.

It is known that the sum of the internal angles of a triangle is equal to 180 °, but how did this claim come about? To prove this, you need to know the common theorems of geometry. Using some of these concepts, you can simply proceed to the demonstration.

Algebraic fractions (or rational functions) can seem extremely complex at first glance and absolutely impossible to solve in the eyes of a student who does not know them. It is difficult to understand where to start by looking at the set of variables, numbers and exponents;

For each test performed on a reference population, it is important to calculate the sensitivity , the specificity , the positive predictive value , and the negative predictive value in order to determine how useful the test is for detecting a disease or characteristic in the target population.

Venn diagrams were actually created by a man named John Venn and are meant to show the relationship between data sets. The idea behind them is quite simple; you just need a pen and paper to start tracing them. Steps Method 1 of 2: Create a Paper Venn Diagram Step 1.

In statistics, absolute frequency refers to the number of times a particular value appears in a data series. The cumulative frequency expresses a different concept: it is the total sum of the absolute frequency of the element of the series under consideration and of all the absolute frequencies of the values that precede it.

A mixed number is an integer close to a fraction, for example 3 ½. Multiplying two mixed numbers can be tricky, because they have to be converted into improper fractions first. To learn how to multiply mixed numbers, follow the simple steps described below.

It is essential to have the ability to convert numbers, fractions and decimals into percentage values, especially in work and in industry, commerce, economics and even engineering. However, it is also very useful in everyday life; We all know how to tip 15%, but how many know how to quickly calculate the amount?

The pie chart is one of the many charts that are commonly used to graph statistical data. It gets its name from the fact that it has a circular shape and is divided into sections that resemble slices of a cake. Each section of a pie chart shows in a simple and intuitive way the part of the total percentage that represents the data it refers to and for this reason a pie chart is a very powerful tool for understanding the meaning of complex data.

The classic form of a second degree inequality is: ax 2 + bx + c 0). Solving the inequality means finding the values of the unknown x for which the inequality is true; these values constitute the set of solutions, expressed in the form of an interval.

The graph of a polynomial or function reveals many features that would not be clear without a visual representation of the graph. One of these features is the axis of symmetry: a vertical line that divides the graph into two mirror and symmetrical images.

Integers are positive or negative numbers with no fractions or decimals. Multiplying and dividing 2 or more whole numbers isn't much different than the same operations on positive-only numbers. The substantial difference is represented by the minus sign, which must always be taken into account.

In mathematics, improper fractions are those in which the numerator (the number above the dash) is greater than or equal to the denominator (the number below the dash). To convert one to a mixed number (a number consisting of an integer and a fraction, such as 2 3/4), you must divide the numerator by the denominator .

The term "cumulative growth rate" is used to describe the increase over a given period as a percentage. It is used to measure past growth, make plans based on projected population growth, estimate cell development, quantify sales growth, and so on.

First degree algebraic equations are relatively simple and quick to solve: most of the time two steps are enough to arrive at the final result. The procedure consists in isolating the unknown to the right or left of the equality sign using the addition, subtraction, multiplication or division operations.

Learning how to calculate the odds of hitting a good hand is of paramount importance to becoming a good poker player. The calculation of percentages is influenced by a large number of variables but can be done using a little bit of math. By learning to calculate the odds of drawing a useful card you can, in the long run, increase your profit margins during the game.

A histogram is a graph that shows the frequency, or number of times, that a given item appears over a specific range. A histogram is similar to a bar chart, but its area is normally used to graphically represent how often a certain item appears.

In differential calculus, an inflection point is a point on a curve where the curvature changes its sign (from positive to negative or vice versa). It is used in various subjects, including engineering, economics, and statistics, to bring about fundamental changes within data.

Finding the center of a circle allows you to solve basic geometry problems; for example, to find the circumference or area of the circle itself. There are several ways to identify this point! You can draw crisscross lines, draw overlapping circles, or use a ruler or ruler.

When you have to make a shipment, you need to know the volume occupied by the package, usually expressed in cubic meters. The precise method for calculating this size depends on the shape of the package. Steps Method 1 of 4: Cuboid Pack Step 1.

The number line is the graphical representation of a straight line on which numbers from the smallest to the largest are written. The number line is a tool for solving simple math problems, and is very useful with small numbers: if the problem you have to solve includes numbers greater than 20 or fractions, using it becomes a little too complicated.

Linear equations with multiple unknowns are equations with two or more variables (usually represented by 'x' and 'y'). There are various ways to solve these equations, including elimination and substitution. Steps Method 1 of 3: Understanding the Components of Linear Equations Step 1.

The doubling time refers to the time it takes to double the growth of specific elements of a group, such as populations or living cells. Knowing the doubling time can be useful for estimating geographic areas where resources may be scarce due to extreme and sudden population increases, or for estimating the rate of growth of cancer, or other harmful cells, to decide if necessary whether to adopt.

The range or rank of a function is the set of values that the function can assume. In other words, it is the set of y values that you get when you put all possible x values into the function. This set of possible values of x is called the domain.

The distributive property states that the product of a number by a sum is equal to the sum of the individual products of the number for each of the addends. This means that a (b + c) = ab + ac. You can use this fundamental property to solve and simplify various types of equations.

A confidence interval is an indicator of the accuracy of measurements. It is also an indicator of how stable an estimate is, measuring how close your measure is to the original estimate if you repeat your experiment. Follow the steps below to calculate the confidence interval for your data.

You have just moved to the United States and you are unable to estimate the speed expressed in miles per hour because you cannot convert the figure to kilometers per hour or you are a cricket enthusiast, but you just can't get used to the speed statistics of the jumps that are indicated with the Anglo-Saxon system.

It is very easy to calculate the third angle of a triangle when you know the measurements of the other two angles. To get the measure of the third angle, all you have to do is subtract the value of the other angles from 180 °. There are, however, other ways to calculate the measure of the third angle of a triangle, depending on the problem you are working on.

While it's easy to sort whole numbers (such as 1, 3, and 8), arranging fractions in ascending order can sometimes be confusing. If the number in the denominator is the same, you can arrange the fractions taking into account only the numerator, ordering them as you would with whole numbers (e.

Solving equations with variables on both sides may seem daunting at first, but once you learn how to isolate the variable by moving it to one side of the equation, the problem will become much easier to handle. Here are some examples for you to review to practice this technique.

Addition is one of the few things we learn in school that is really required of us in everyday life. Fortunately it is easy to learn; some rules are required, depending on the kinds of numbers to add, but wikiHow has it all under control. Just start from the first point!

Algebra is important and indispensable for tackling the most advanced mathematics topics during middle and high school. However, some basic concepts can be a bit complex for beginners to understand for the first time. If you have some difficulty with the fundamentals of algebra, don't worry;

The correlation coefficient, denoted by “r”, is the measure of the linear correlation (the relationship, in terms of both strength and direction) between two variables. It ranges from -1 to +1, with plus and minus signs used to represent positive or negative correlation.
