What is the Roman numeral for 15?

One of the basic rules for writing numbers in Roman Numerals is that only seven symbols can be used and no more. These seven symbols are I, V, X, L, C, D, and M. It is also important to understand that when a symbol for a smaller number is written before a symbol for a larger number, it is subtracted from the larger number. If a symbol for a smaller number is written after a symbol for a symbol for a larger number, it is to be added to the symbol for the larger number.

What does solving formulas for the indicated variable involve?

Solving for the variable "h" gives the new equation h = 2A/b, where b is the base and A is the area. Similarly, students can be asked to solve for indicated variables in physics and chemistry formulas, such as V = I x R and P1 x V1 = P2 x V2.Ohm's Law is given as V = I x R, where V equals volts, I represents current and R is resistance. A simple calculation students may need to do is to solve for the variable I in this formula. Solving for I or current, the equation should be manipulated to give the answer as I = V/R.In chemistry, Boyle's Law is given by the formula P1 X V1 =P2 X V..

How are Roman numerals used today?

Roman numerals are commonly used in textbooks and other books for the pages preceding the first chapter as well as those in the appendices. Roman numerals are also used after names to show succession, such as with the pope and family names that are passed down through the generations.

What is the outlier in a math problem?

Before determining if a data point is an outlier, the normal data point value range must be determined. To do so, a random sample of a population must be taken, and the data points must be ordered from smallest to largest. The normal range for the data set will include the majority of the points, while the outliers will be a lot smaller or a lot larger than any of the data points.

How are statistics used in accounting?

Forensic accountants depend on statistical methods to analyze financial instruments that may be used to perpetrate financial fraud. By understanding statistical principles, forensic accountants correctly estimate whether the valuation of the risk associated with financial instruments was appropriate.\nControllers are typically in charge of all the financial operations of a company. Some of their main responsibilities are to perform cost analyses, provide financial forecasts and compile budget reports. Controllers apply their knowledge of statistics to develop the appropriate forecasts and anal..

What is a direct formula?

The direct variation formula is written as y = kx; where, k is the constant of variation and y and x are the variables. The graph of the direct variation formula is a straight line in cases where the constant of variation is greater than zero. An example of a direct variation formula is the formula for the area of a circle.

Does a cone have a vertex?

When looking for the volume of a cone, the formula V = 1/3(Ab)(h) is used, where Ab is the area of the base and h is the height. Further, the base area can be solved using the formula for getting the area of a regular circle, which is Ab = (pi)(r^2), where r is the radius. Thus, the formula for the cone's volume can also be written as V = 1/3(pi)(r^2)(h).

What are the factors of 40?

The factors of a number are those that divide evenly into the number in question. To factor a number, it is expressed as a product of smaller numbers which is referred to as factorization. For example, factoring the number 12 would result in 3 x 4, but it can be further factored as 12 = 2 x 2 x 3. If a number can not be factored any further, it is known as a prime number. The greatest common factor is the greatest number that two numbers have in common. For instance, the greatest common factor of 16 and 12 is 4 because it is the largest number that can be evenly divided into both numbers.

How many lines of symmetry does an oval shape have?

An oval figure can be divided down the middle, both lengthwise and vertical, with the result of the two halves matching each other. The oval cannot be divided on an angle other than straight across or up and down. This results in two halves that do not match up. Circles and some triangles are also symmetrical figures.

How many corners does a cuboid have?

If all the sides of a cuboid are the same length, it is a "cube." To find the volume of a cuboid, multiply the measurements of its length, width and height. To determine the total surface area of a cuboid, multiply the length of each dimension by each of the others, and then add the products together. Finally, multiply the total by two. For instance, if length equals seven, width equals five and height equals three, the equation is 2(7 x 5 + 5 x 3 + 7 x 3) = 142.
