WGU C955 New Key Rules and Formulas for Applied Probability and Statistics

WGU C955 New Key Rules and Formulas for Applied Probability and Statistics Changing Improper Fractions and Mixed Numbers - Improper fractions can be converted to mixed numbers by following these steps: Write division problem with numerator divided by denominator. Divide to determine quotient and remainder. Write mixed number with the quotient as the whole number and the remainder as the numerator over the same denominator. Changing Mixed Numbers Into Improper Fractions - Mixed numbers can also be converted to improper fractions by following these steps: Multiply the whole number by the denominator of the fraction. To the product given by step 1, add the number of the numerator. Write the result of step 2 as the numerator of the improper fraction. The denominator of the improper fraction should be the denominator of the original fraction. Simplify the improper fraction by diving the numerator and denominator by all common factors. Discrete Data - Has distinct values, can be counted, has unconnected points (dots) Continuous data - Has values within a range, measured (not counted) does not have gaps between data points. (connected lines or curves) Sign rule for Multiplication and division - 1. +# x +# = +# 2. -# x -# = +# A product or division of two numbers of the same sign will result in a positive number 3. -# x +# = -# 4. +# x -# = -# A product or division of two numbers of different signs will result in a negative number Prime Number - A prime number is a number that has exactly two positive factors; 1 and itself. Composite Number - A number that is not prime. It has 2 or more positive factor, including 1 and itself. Prime Factorization - Writing the number as a product of only prime numbers
