What is a "coordinate plane"?

Math Open Reference states that points, lines and curves can be plotted on a coordinate plane. Moreover, the two axes divide the coordinate plane into four parts called quadrants. The top right part is called the first quadrant and on the top left is the second quadrant. The third quadrant is located below the second quadrant, and the fourth quadrant is below the first quadrant.

What is a Pareto chart?

A Pareto chart is commonly used in quality-control metrics. When analyzing a quality-control distribution model, a small number of issues typically account for a considerable amount of defects. By identifying and solving for the greater factor set, the greatest improvement can be made to the system.\nA Pareto chart allows for the analysis of data to determine the frequency of a problem in a process or system, when it is important to focus on the most significant factor, when analyzing specific components of a larger system, and when communicating the analysis of the data.\nA Pareto chart of a ..

How do I calculate the percentage of a sum?

Calculate the percentage fractionValue of a percentage is the same as the numerator in a percentage fraction. The numerator of a fraction is the number on top. For example, 15 percent is the same as 15/100, which can also be written as 0.15. A simple way to find the percentage fraction is to move the decimal of the percentage two places to the right. Multiple the sum by the percentage fractionMultiply the sum by the percentage fraction to find the percentage of the sum. For example, if you want to find the 15 percent of the total sum 3500. To find 15 percent of 3500, multiply 3500 by 0.15. 35..

How do you use a multiplication time table chart?

When using a times table, there is no difference between multiplying a row by a column and multiplying a column by a row because of the commutative property. This means that the intersection of column 2 and row 9 has the same solution as the intersection of column 9 and row 2, both of which result in 18.\nWhile times tables are made with an easy-to-read layout, their purpose is usually to streamline memorization of basic multiplication problems by students. A common recommendation is to first memorize the table between column and row 5, therefore starting with the smallest factors.\nTimes tabl..

How do you calculate the sum of an arithmetic sequence?

Determine the difference between termsFind the arithmetic value that describes the difference between each term in the series, and set it equal to d. For example, the series {1, 2, 3} has a difference of 1 between each term, while the series {0, 3, 6, 9} has a difference of 3.Find the number of terms in the seriesThe number of terms added together in the series is represented by the variable n, so count up the total number of terms you want to find the sum of. For example, the series {2, 4, 6, 8} has four terms, so the value of n would be 4.Plug the numbers into the equationUsing the equation ..

What is the formula for the circumference of a circle?

If the radius of the circle is 14 centimeters, then the circumference is 2 x 22/7 x 14, which equals 88 centimeters. If the diameter of the circle is given, then the formula for circumference is πd, where d is the diameter. If the diameter of the circle is given as 21 centimeters, then the circumference is 22/7 x 21, which equals 66 centimeters.\nIn one revolution of a wheel, the distance covered by the wheel is equal to the circumference of the wheel.

Is the number 121 a prime number?

A prime number is not divisible by any other number other than the number 1 and itself. To find out if a number is prime number its factors are obtained. The factors of 121 are 1, 11 and 121. Similarly, the factors of 43 are 1 and 43 only. This makes 43 a prime number. However, the number 50 has 1, 2, 5, 10 and 50 as its factors. Thus 50 is not a prime number but a composite number.

How many miles are in 5,000 kilometers?

Some people mistakenly believe that a "5k race" has 5,000 kilometers because "k" often represents 1,000. However, "5k" in this instance standards for 5 kilometers. Therefore, a standard 5k race is approximately 3.1 miles.\nOne fairly standard application of measurements using 5,000 kilometers is in car maintenance. Some service shops recommend 5,000-kilometer oil changes, which is almost the same as the traditional 3,000-mile recommendation that most shops use.

How do you factor each polynomial completely?

Factor the greatest common factor from the expressionIn the example, 12x^4 - 3x^2 - 54, the greatest common factor is 3. Therefore, the 3 is removed from the initial equation, and the expression becomes 3(4x^4 - x^2 - 18). If there is no greatest common factor to be found, this step may be skipped.Factor a trinomialIf there are more than two terms in an expressions, it may be factored into a trinomial. In the example, 3(4x^4 - x^2 - 18), the expression would become 3(4x^2 - 9)(x^2 + 2) when factored.Factor a difference between two squaresFinally, in the example 3(4x^2 - 9)(x^2 + 2), (4x^2 - 9)..

What is the ALT code for the square root symbol?

The square root symbol is extremely common in mathematics starting at the prealgebra level. The square root of a number is any number that when multiplied by itself gives the original value. While the positive square root is generally the one people are most interested in, there are also negative square roots. For instance, the square roots of 144 are both -12 and 12.
