- True or False Label each of the following statement as either true or false. 1. Parity check schemes will always detect the position of an error.arrow_forwardDetermine whether the set S={2x+x2,8+x3,x2+x3,4+x2} spans P3.arrow_forwardWhich of the following pairs of keywords in Java are often used to declare values that must remain constant: (A)static, final (B) public, void (C)abstract, this (D) this, superarrow_forward
- A password has n characters ordered in a row. Each character can be either a letter A,B,C or a number 0,1,2. The password MUST start with a letter and satisfy the restrictions following (applied unless a character ends the password). A can be followed by any letter; and 0,1,2 can be followed by any number. B can be followed by A or any number. C can be followed by A or any number Let X, be the number of passwords, give an explicit formula for X, and compute the limit of Xn+1/Xnarrow_forwardAt one point, license plates in a certain state consisted of 2 letters (excluding I, O, Q, and W), followed by 4 numbers. Complete parts (a) through (e) below. a) How many plates are possible when letters and numbers can repeat? Set up the expression that can be used to calculate the number of plates that are possible when letters and numbers can repeat. The expression is (Do not simplify.) The number of plates possible when letters and numbers can repeat is (Use scientific notation. Use the multiplication symbol in the math palette as needed. Round to three decimal places as needed.) b) How many plates would be possible if letters could repeat but numbers could not? (Use scientific notation. Use the multiplication symbol in the math palette as needed. Round to three decimal places as needed.) c) How many plates would be possible if letters could not repeat but numbers could? (Use scientific notation. Use the multiplication symbol in the math palette as needed. Round to three decimal…arrow_forwardb. Identify the systems from task (2a) that demonstrate closure, i.e., theresult of the operation always produces an element in the set.c. Identify the systems from task (2a) that have an identity element.arrow_forward
- Assume that there are 10 girls and 8 boys in the neighborhood club, and a team of 8 is to be selected. How many different teams can be selected if each team must contain both boys and girls?arrow_forwardIf there were only 3 types of music in the world: pop, rock and rap. Let set A equals all the people in the world who prefer pop music, what is A complement.arrow_forwardThe name of a variable in the new programming language K is a string that can contain upper case letters, lowercase letters, digits or underscores. Further, the first character in the string must be a letter, either uppercase or lower case or an underscore. If the name of a variable is determined by its eleven characters, how many different variables can be named in this programming language? ( Note: a name of a variable may contain fewer than eleven charactersarrow_forward
- you were introduced to the set operations of "union", "intersection" and "complement." Do you see a connection between these set operators and logical operators such as "AND", "OR" and "NOT"? Can you describe what this connection is? And what about electronic switching circuits? Is there a connection there as well?arrow_forwardShow that on a street with 101 houses where each house has a distinct street numberbetween 1 and 200, there must be two houses with consecutive numbers.arrow_forwardA freelance computer consultant keeps a database of her clients, which contains the names S = {Acme, Brothers, Crafts, Dion, Effigy, Floyd, Global, Hilbert). The following clients owe her money: A = (Acme, Crafts, Effigy, Global}. The following clients have done at least $10,000 worth of business with her: B = {Acme, Brothers, Crafts, Dion). The following clients have employed her in the last year: C = {Acme, Crafts, Dion, Effigy, Global, Hilbert). A subset of clients is described that the consultant could find using her database. HINT [See Example 4.] The clients who either do not owe her money, have done at least $10,000 worth of business with her, or have employed her in the last year. Write the subset in terms of A, B, and C. OA'UBUC OAUBUC OAUB'UC' OA'UBUC OA'UBUC List the clients in the subset.
