# Alphabetical Lesson List: (14) lessons starting with the letter N

 [+] N-GramsTakes a phrase and displays chracter unigrams, character bigrams, character trigrams, and character n-grams as well as word unigrams, word bigrams, word trigrams, and word n-grams. (ngrams)Also performs frequency analysis (number of instances of each letter)Features: Calculator | Watch the VideoTags: character, word [+] Natural NumbersShows a set amount of natural numbers and cumulative sumFeatures: Calculator | Practice Problem GeneratorExamples (1):250 natural numbers [+] Negative Binomial DistributionCalculates the probability of the kth success on the xth try for a negative binomial distribution also known as the Pascal distribution.? ? It calculates the probability of exactly k successes, no more than k successes, and greater than k successes as well as the mean, variance, and standard deviation.Features: Calculator | Quiz Generator | Practice Problem Generator | Watch the VideoTags: binomial, distribution, event, mean, probability, standard deviation, variance [+] Net Present Value (NPV) - Internal Rate of Return (IRR) - Profitability IndexGiven a series of cash flows Ct at times t and a discount rate of (i), the calculator will determine the Net Present Value (NPV) at time 0, also known as the discounted cash flow model. Profitability Index Also determines an Internal Rate of Return (IRR) based on a series of cash flowsFeatures: Calculator | Quiz Generator | Practice Problem Generator | Watch the VideoTags: cash flow, discount rate, interest, present value, return [+] Newton MethodCalculates the square root of a positive integer using the Newton MethodFeatures: Calculator | Quiz Generator | Practice Problem GeneratorExamples (1):Newton method sqrt(50) [+] Nominal YieldGiven an effective annual rate of interest based on a compounding period, this determines the nominal yield.Features: Calculator | Practice Problem GeneratorTags: compound, effective rate, nominal rate [+] NonagonCalculates the side, perimeter, and area of a nonagonFeatures: Calculator | Practice Problem GeneratorExamples (60):Nonagon side = 1Nonagon area = 1Nonagon perimeter = 1Nonagon side = 2Nonagon area = 2Nonagon perimeter = 2Nonagon side = 3Nonagon area = 3Nonagon perimeter = 3Nonagon side = 4Nonagon area = 4Nonagon perimeter = 4Nonagon side = 5Nonagon area = 5Nonagon perimeter = 5Nonagon side = 6Nonagon area = 6Nonagon perimeter = 6Nonagon side = 7Nonagon area = 7Nonagon perimeter = 7Nonagon side = 8Nonagon area = 8Nonagon perimeter = 8Nonagon side = 9Nonagon area = 9Nonagon perimeter = 9Nonagon side = 10Nonagon area = 10Nonagon perimeter = 10Nonagon side = 11Nonagon area = 11Nonagon perimeter = 11Nonagon side = 12Nonagon area = 12Nonagon perimeter = 12Nonagon side = 13Nonagon area = 13Nonagon perimeter = 13Nonagon side = 14Nonagon area = 14Nonagon perimeter = 14Nonagon side = 15Nonagon area = 15Nonagon perimeter = 15Nonagon side = 16Nonagon area = 16Nonagon perimeter = 16Nonagon side = 17Nonagon area = 17Nonagon perimeter = 17Nonagon side = 18Nonagon area = 18Nonagon perimeter = 18Nonagon side = 19Nonagon area = 19Nonagon perimeter = 19Nonagon side = 20Nonagon area = 20Nonagon perimeter = 20 [+] Nonagonal NumberThis calculator determines the nth nonagonal numberFeatures: Calculator | Practice Problem GeneratorExamples (2):30th Nonagonal number45th Nonagonal numberTags: nonagon, number [+] Normal DistributionCalculates the probability that a random variable is less than or greater than a value or between 2 values using the Normal Distribution z-score (z value) method (Central Limit Theorem). Also calculates the Range of values for the 68-95-99.7 rule, or three-sigma rule, or empirical ruleFeatures: Calculator | Quiz Generator | Practice Problem GeneratorExamples (3):P(Z>1.5)P(Z<2.15)The amount of Jens monthly phone bill is normally distributed with a mean of \$73 and a standard deviation of \$12. What percentage of her phone bills are between \$37 and \$109?Tags: distribution, event, mean, probability, standard deviation, variance, z score [+] Number BondsAdds or subtracts 2 numbers and using grouping by 10 or 100. Also called number bonds or addition facts. Multiplies two numbers using tape diagrams.Features: Calculator | Practice Problem GeneratorExamples (3):12+1511+79*7 [+] Number LineCounts from a point going left and right on a number lineFeatures: Calculator | Quiz Generator | Practice Problem GeneratorTags: addition, number line, subtraction [+] Number Line MidpointCalculates a midpoint between 2 points on a number line or finds the second endpoint if one endpoint and midpoint are given.Features: Calculator | Quiz Generator | Practice Problem Generator | Watch the VideoExamples (3):midpoint 2,5midpoint of 2 and 6mpt 3,5Tags: midpoint, number line, points [+] Number PropertyThis calculator determines if an integer you entered has any of the following properties: * Even Numbers or Odd Numbers (Parity Function or even-odd numbers) * Evil Numbers or Odious Numbers * Perfect Numbers, Abundant Numbers, or Deficient Numbers * Triangular Numbers * Prime Numbers or Composite Numbers * Automorphic (Curious) * Undulating Numbers * Square Numbers * Cube Numbers * Palindrome Numbers * Repunit Numbers * Apocalyptic Power * Pentagonal * Tetrahedral (Pyramidal) * Narcissistic (Plus Perfect) * Catalan * RepunitFeatures: Calculator | Practice Problem Generator | Watch the VideoExamples (6):30 as a unique number45 as a composite numbernumerical properties of 100properties of 35tell me about 72A(4)Tags: cube, divisor, even, number, odd, palindrome, pentagon, perfect, property, pyramid, square [+] Numbers Word ProblemsSolves various basic math and algebra word problems with numbersFeatures: Calculator | Practice Problem GeneratorTags: consecutive, integer, word problem
