Answer:
(10000000)₂ = -128 in decimal
(11001100)₂ = -52 in decimal
(10110111)₂ = -73 in decimal
Explanation:
<u>NOTE:</u> If Most Significant Bit is 0, it is positive number and if MSB is 1, it is negative number. If number is positive we can simply convert it to decimal. But if number is negative, follow following formula:
- (complement of the number) +1
<u>EXAMPLE 1</u>
(10000000)₂
(01 1 1 1 1 1 1)₂ ↔ complement of the number
<u>+ 1</u>
(10000000)₂ = 1 ×
= 128 (magnitude in decimal)
But we remember MSB was 1 so answer is -128.
<u>EXAMPLE 2</u>
(1 1 0 0 1 1 00)₂
(0 0 1 1 0 0 1 1)₂
<u>+ 1 </u>
(0 0 1 1 0 1 0 0)₂ = 52 (magnitude in decimal)
But we remember MSB was 1 so answer is -52.
<u>EXAMPLE 3</u>
(1 0 1 1 0 1 1 1)₂
(0 1 00 1 000)₂
<u>+ 1 </u>
(01 00 1 00 1)₂ = 73 (magnitude in decimal)
But we remember MSB was 1 so answer is -73.
Answer:
D. Aptitude is a person’s potential to learn new skills.
Explanation:
A. Aptitudes are ability, and skills are the potential.
B. Aptitudes can be learned or trained, unlike skills.
C. Aptitude is the level of skill that a person has gained.
D. Aptitude is a person’s potential to learn new skills.
Out of the above four, the A and B part is wrong and the rest of the options are right. Skills are the ability and aptitude is the potential, and the aptitude is the level of skill which person has gained, as well as Aptitude, is the Person's potential to learn new skills. However, D is adequate, and C can be derived out of it, as if someone has potential, the better level of skills he/she will gain. Hence, D is the correct option.
An overhead projector is required to display content on transparencies. A transparency is a thin sheet of plastic in which light is reflected upon to display content.The light source emits light towards the transparency and then the image is displayed on the wall. Usually, this light source comes from below and lights upward and so the content is depicted above or overhead.
