Math 5158 Praxis Latest 2024 Graded A+ Negation If a statement is represented by p, then not p is the negation of the statement. A proposition that is true if and only if another proposition is false. "All p is q - negation can be some p is not q" (draw Venn) Units digit the digit in the one's place y as a function of x Vertical line test - can't intersect more than once Rhombus A parallelogram with four equal sides Set Collection Identity property of set if there is an e...

ABCTE -Mathematics: Working with Powers and ExponentsBasic Rules of Exponents - correct answer Raising to the First Power For any non-zero number a, a1 = a. 61 = 6 Raising to the Zero Power For any non-zero number a, a0 = 1, by definition. 60 = 1 Negative Exponents For any non-zero number a and integer n, a-n = 1/an. Advanced Rules - correct answer Multiplying Powers with the Same Base For any non-zero number a and integers m and n, . (Add the exponents when multi...

Algorithm - At its core, an algorithm is really just a generalized, conceptual solution to a problem that can later be implemented in some real-world form like a computer program. Application Program Interface - Application program interface (API) is a set of routines, protocols, and tools for constructing software applications. An API specifies how software components should interact. In addition, APIs are used when programming graphical user interface (GUI) components. Binary - A numeric ...

Real numbers - are numbers that have a specific value. Real numbers can be rational or irrational. Within rational numbers, there are integer, whole, and natural numbers. Rational numbers - are numbers that can be expressed as a ratio (fraction or comparison) of two integers, a/b where b ≠ 0 (because zero can't be the denominator of a fraction). All rational numbers can be written exactly in both fraction and decimal forms, and can be graphed on a number line. Note that exact is a formal...

Rational number (aka 'fractional') Numbers that can be expressed as a fraction Integers Solid positive and negative numbers 00:5301:34 Real Numbers A real number is any number that can be placed on the number line, whether that be negative or positive, fraction or decimal. True or False? Any integer is also a whole number. This statement is false. An integer can be negative, such as the number −100-100. −100- 100 is not a whole number. Read all the options before answering. −1...

Amanda is measuring the temperature. She looks at the thermometer and sees that it is somewhere between 65 and 66 degrees Fahrenheit. She is okay with the temperature in between two integers because she knows temperature is not ________ data, but temperature is _________ data.  a) Nominal, Ordinal  b) Nominal, Discrete  c) Continuous, Discrete  d) Discrete, Continuous Feedback: The correct answer is D. Temperature is not a measure that comes in increments (discrete) but is co...

Algorithm efficiency typically measured by the algorithm's computational complexity Computational complexity the amount of resources used by the algorithm. The most common resources considered are the runtime and memory usage. runtime complexity a function, T(N), that represents the number of constant time operations performed by the algorithm on an input of size N Space-complexity (of an algorithm) a function, S(N), that represents the number of fixed-size memory units...

The development of number systems: Z + , Z ≥ and Z Positive integers: Z + Z + = {1, 2, 3, …} Law 1-7 Non-negative integers: Z ≥ Z ≥ = {0, 1, 2, 3, …} Law 1-9 Integers: Z Z = {... , -3, -2, -1, 0, 1, 2, …} Law 1-10 (Law 6 is different) and Def 1-3 The Laws for Z+ and Z≥ Law 1 (commutativity): For all non-negative integers m and n, m + n = n + m and mn = nm. Law 2 (associativity): For all non-negativ...

Consists of public and private keys The public key is made public by publishing to a directory or installed on a computer. The private key is kept secret Does not involve exchanging a secret key or key exchange The public key is used to encrypt messages only the recipients private key can decrypt - -Asymmetric Cryptography Slower then Symmetric algorithms provides a secure way to communicate provides a method of validation Non-repudiation - -Disadvantages and Advantages of Asymmetric Cr...
