Unformatted text preview: d one (0<x<1) from a uniform distribution, press . To repeat a sequence of random numbers, you must store a "seed" value in the random number generator. To store a seed value, key in an integer greater than zero and press D . This lets you recreate experiments by generating the same series of random numbers. Combinations The key sequence calculates the number of combinations of n items taken r at a time. nCr = n! ( n − r )! × r ! Permutations The key sequence calculates the number of permutations of n items taken r at a time. n Pr = 8 n! ( n − r )! Chapter 1: Overview of Calculator Operations Rounding The round function is useful when you need to perform a calculation using the displayed form of a number rather than the unrounded value that the calculator stores internally. The decimal format setting does not round the calculator's internally stored value, only the displayed value. The round key sequence match its displayed form. lets you change the internal value to Internal value Displayed value After rounding Before rounding For example, in the Bond worksheet, you might want to round a computed selling price to the nearest penny (two decimal places) before continuing with your calculation. Scientific Notation If you compute a value that is larger or smaller than the calculator can display in standard decimal format, the value is displayed in scientific notation. A value in scientific notation is displayed as a base value (often called a mantissa), followed by a blank space, followed by an exponent. You cannot directly enter a number in scientific notation, but when the AOS calculation method is selected, you can use the key to enter a number in scientific notation. For example, for 3 10 3, type 3 < 10 3. Memory Operations Your calculator always has 10 memories available. The memories can hold any numeric value within the range of the calculator. The memories are numbered 0 through 9. This lets you access each memory using a single keystroke. Chapter 1: Overview of Calculator Oper...
