To calculate the 10's complement of the number 29, you first find its 9's complement, which is 70. What is the 10's Complement?. 70. 71. 69. 80.

To calculate the 9's Complement of a decimal number, you subtract each digit from: 10. 9. 5. 1.

How do you get the Two's Complement from the One's Complement?. By flipping the bits again. By subtracting(2) 1 from the One's Complement. By adding(2) 1 to the One's Complement. By ignoring the leading digit.

When subtracting using complements, what should you do with the final carry digit?. Add it to the next digit. Multiply it by two. Leave it as it is. Ignore it.

Based on the example in the file, what is the Two's Complement of the binary number 0101(2)?. 1010(2). 1011(2). 0101(2). 0001(2).

What is the 9's Complement of the number 635?. 635. 365. 463. 364.

In the binary system, what do you do to each bit to find the One's Complement?. Multiply it by 2. Subtract it from 10. Invert it (flip it) from 0 to 1 and 1 to 0. Add 1 to it.

In subtraction using complements, you must first find the complement of the: Subtracted from. Subtrahend. Final result. Leading digit.

In the decimal subtraction 8 - 6 using complements, you add 8 to the 10's complement of 6 (which is 4). What is the result of this addition before you ignore the carry digit?. 2. 4. 12. 8.

What is the main disadvantage of the Bitmap format compared to the Vector format?. It reduces the number of pixels in the image. It only allows for representing text and shapes. It causes symbols to appear unreadable when printed. Jaggies appear when the image is enlarged.

According to the LATCH principle, which type of classification is based on the sequence of events over time?. Location. Alphabet. Time. Category. Visualization.

What is the term that refers to visually representing data to make it more understandable, with examples including tables, charts, etc.?. Abstraction. Pictogram. Structuring. Visualization.

In the 24-bit full color system, what is the number of color levels that can be represented for a single primary color (like Red)?. 8 levels. 24 levels. 256 levels. 224 levels.

What is the concept that refers to how easily data and services can be accessed by a wide range of people, including those with special needs?. Affordance. Usability. Accessibility. Universal design.

What are the three primary colors of light which, when mixed, increase in brightness and approach white?. Cyan, Magenta, and Yellow. Red, Green, and Blue. Violet, Yellow, and Black. White, Gray, and Black.

The smallest unit that defines the shape of a digital image, where the image is represented by its arrangement, is: Resolution unit (dpi). The Pixel. Sampling. Encoding.

What is the interface where icons and buttons are used in an easy-to-understand way to exchange information between humans and devices?. Command Line Interface (CUI). User Interface (UI). Graphical User Interface (GUI). User Experience (UX).

If the image size in pixels is X pixels (vertical) $\times$ Y pixels (horizontal), and each pixel is represented by Z bits, what is the correct equation that represents the data size (in bits)?. X x Y. X x Y x Z. Z. + ( X x Y). X x Y x {Number of primary colors}.
