What is percent uncertainty?

For example, consider Andrew, who steps on a scale with a relative error, or uncertainty, of plus/minus 5 pounds. Due to the potential inaccuracy of the scale, if Andrew weighs in at 180 pounds, he could theoretically weigh as little as 175 or as much as 185 pounds. Therefore, when dividing the uncertainty (5) into Andrew's perceived weight (180), the result is 0.02777777, or an uncertainty of 2.7 percent.

If point A is collinear with points B, C, D and so on, that means that there is a straight line that contains all of these points. Any two points are collinear, because a line can be drawn through them. Three points that are not collinear make up a triangle; however, three points that are collinear create a triangle with an area of zero.

Breakfast math requires a frozen waffle and some blueberries. Place the waffle on a plate, and allow the child to arrange the blueberries on the waffle. Call out random numbers or fractions, and ask him to place the correct number of blueberries into the grooves of the waffle. Cheer and continue until he has learned the sequence satisfactorily.\nShake It is a numbers-recognition game. It requires an empty egg carton, a marker and a small object like a button. Use the marker to write numbers from one to 12 on each dimple of the carton and drop the button inside. Ask the child to close the carto..

Recognize the common base numberIn some math expressions, the base numbers are given. In the formula 9^3 times 9^5, for instance, the base number is 9 in each case. In algebraic expressions, the formula might show x^3 times x^5.Add exponent numbers and combine the basesTo multiply two like base numbers, add the exponents and merge them into one. In 9^3 times 9^5, adding the exponents 3 and 5 equals 8. Therefore, this two-part formula is simplified to 9^8.Solve the equationUse the simplified base number and exponent to solve the equation. If the objective was to solve for x when you multiply 9^..

Calculator Soup gives the least common multiple of a group of numbers that are separated by commas. The user clicks the calculate button and the LCM generates.\nThe Alcula calculator computes what the least common multiple is for a set of two to 10 numbers. This website also explains that the lowest common denominator is another term for the least common multiple; this is because it allows math users to quickly find the common denominator of fractions that they need add or subtract.
What is a fixed variable in an experiment?

During scientific experimentation, it is extremely important to perform each part of the experiment in an identical manner to the last in order to prove that the results were directly influenced by the single variable that changed. A fixed variable is anything experimenters can ensure stays the same throughout experimentation, such as ambient room temperature or brand of chemical. Any variable that is immeasurable or uncontrollable is considered an extraneous variable, and ideally has little effect on the results of the experiment.
What are corresponding angles?

There are eight angles formed when a transversal crosses two parallel lines. Besides corresponding angles, there are other types of angles formed, including vertical angles, interior angles and exterior angles. While interior angles are the four angles that occupy the space between the parallel lines, the angles that are on the outer side of the parallel lines are exterior angles. Some other types of angles formed are adjacent angles, consecutive interior angles, alternate interior angles and alternate exterior angles. Adjacent angles form a linear pair or are supplementary, which means that t..
What is the prime factorization of 76?

The number 76 also has two non-prime factors, which are 4 and 38. One can find the prime factorization of 76 by writing down 76 = 4 x 19 or 76 = 2 x 38. Either of these factorizations can be reduced to the prime factorization of 76 = 2 x 2 x 19 by factoring the non-prime factors into their prime factors: 4 = 2 x 2 or 38 = 2 x 19.
What is the square root of 113?

The square root can be determined by finding a number, y, that when multiplied by itself equals the number x, such that y times y equals x. Although sometimes the square root formula can be simplified by factoring out the square root of a whole number, this process is not possible with 113 because it is not a multiple of any of the lower square roots of whole numbers.
What is the probability union?

If two events are mutually exclusive, then the probability of one of them happening can be calculated by adding together the probabilities for each event. For example, when rolling a die, the chance of getting a 5 or greater is 2 out of 6 possibilities, and the chance of getting a 2 or lower is also 2 out of 6. The probability for these two events adds up to 4 out of 6, which equals a two-thirds chance of the union occurring.\nHowever, if two events are not mutually exclusive, then the probability of the intersection needs to be subtracted from the equation. The reason is that double-counting ..
