WGU C955 New Key Rules and Formulas for Applied Probability and Statistics Latest Version 100%Solved. Module 1 Data Classification A. Discrete data has the ability to be counted, has distinct values, and has unconnected points (think "dots"). B. Continuous data are measured instead of counted, have values within a range, and do not have gaps between data points (think of data as "connected lines" or "curves"). Intervals A. The phrases "less than" and "greater than" correspond to open intervals and are marked with parentheses. B. The phrases "less than or equal to" and "greater than or equal to" correspond to closed intervals and are marked with brackets. Sign Rule for Multiplication and Division A. (positive) ∙ (positive) = (positive); and (negative) ∙ (negative) = (positive) That is, a product or quotient of two numbers of the same sign results in a positive number. B. (negative) ∙ (positive) = (negative), and (positive) ∙ (negative) = (negative) That is, a product or quotient of two numbers of different signs results in a negative number. Prime and Composite Numbers A. A prime number is a number that has exactly two positive factors, 1 and the number itself. B. A composite number is a number that is not prime; this means that it has three or more positive factors, including 1 and the number itself. Prime Factorization Prime factorization is the process of writing the number as a product of prime numbers only. Greatest Common Factor The greatest common factor (GCF) of two or more numbers is the largest number that divides all the given numbers evenly. Module 2 Multiples of a Number These are numbers that can be obtained by multiplying the given number by 1, 2, 3, 4... . Least Common Multiple (LCM) The LCM of two or more numbers is the smallest positive number that can be divided by the given numbers. Unit Conversions This is an incomplete list, showing only the most common conversions. A complete list can be found in MindEdge on page 2.15. Unit Conversions for Household Measures of Volume • 1 tablespoon = 3 teaspoons • 1 fluid ounce = 2 tablespoons • 1 cup = 8 fluid ounces 2 • 1 pint = 2 cups • 1 quart = 2 pints • 1 gallon = 4 quarts Common Metric Conversions • 1 l = 1000 ml • 1 kg= 1000 g • 1 g = 1000 mg (milligrams) • 1 mg = 1000 mcg (micrograms) Conversion between Household and Metric Units • 1 cc (cubic cm) = 1 ml • 1 fl oz = 30 ml • 1 L = 1.057 qt • 1 tsp = 5 ml • 1 kg = 2.2 lb • 1 oz = 28.35 g Temperature Conversions • Fahrenheit = (Celsius ∙ 9 5 ) + 32 • Celsius = (Fahrenheit - 32) ∙ 5 9 • Shorthand version of the formula for converting from Celsius to Fahrenheit: F = 1.8C + 32 Module 3 Like Terms Like terms are terms that have the same variable(s) raised to the same power(s); they can be combined using addition and subtraction. Addition/Subtraction Principle We can add/subtract the same number to both sides of an equation and the resulting expressions remain equal. Multiplication/Division Principle We can multiply/divide both sides of an equation by the same number and the resulting expressions remain equal (division by zero is not allowed). The Butterfly Method ("Cross-Multiplication") If
