Identify the invisible character, convert hexadecimal A0 to decimal, and convert binary 110.101's fractional part to decimal.

Welcome back RÉSPÊÇT📿☝️.......🙏🙏🔐 — missed you this week. Here are the answers to the objectives: 1. D) A space character is invisible when typing on the computer; it creates a gap but has no visible mark itself. A caret, exclamation, and other characters are visible. The correct option is D. D. Space 2. C) To convert the hexadecimal number A0 to decimal: Step 1: Identify the place values. In hexadecimal, A is 10_10 and 0 is 0_10. Step 2: Multiply each digit by the corresponding power of 16. A0_16 = (10 × 16^1) + (0 × 16^0) Step 3: Calculate the values. = (10 × 16) + (0 × 1) = 160 + 0 = 160_10 The correct option is C. C. 160 3. C) To find the decimal representation of the fraction part of the binary number 110.101: Step 1: Identify the fraction part, which is .101. Step 2: Convert each digit in the fraction part to its decimal equivalent using negative powers of 2. 0.101_2 = (1 × 2^-1) + (0 × 2^-2) + (1 × 2^-3) Step 3: Calculate the values. = (1 × 0.5) + (0 × 0.25) + (1 × 0.125) = 0.5 + 0 + 0.125 = 0.625_10 The correct option is C. C. 0.625 4. A) When a record is stored according to a primary key and the file management system creates an address for each record, this describes indexed-sequential file organization. This method allows both sequential processing and direct access via an index. The correct option is A. A. indexed-sequential 5. D) Tactical information is used for short-term planning and decision-making to implement strategic goals. This type of information is primarily required by middle managers who are responsible for implementing the plans developed by top management. The correct option is D. D. middle managers 6. D) Information is processed, organized, structured, or presented data that makes it useful. A list of items, recorded observations, and individual student scores are raw data. The average scores of students in a test is data that has been processed (calculated) to provide a meaningful insight, making it an example of information. The correct option is D. D.
