When you copy cells, cell references automatically adjust. But, when you move cells, cell references are not adjusted, and the contents of those cells and of any cells that point to them may be displayed as reference errors. In this case, you have to adjust the references manually.
If the selected copy area includes hidden cells, rows, or columns, Excel copies them. You may have to unhide data temporarily you don't want to include when you copy information.
Hope this helps! I'm not a computer genius though
Answer:
answer is 8! / (4! * 4!). Which gives a value of 70.
Explanation:
we have 8 places, we’re going to pick 4 places to put the zeros, it is 8! / (4! x 4!)
Answer:
Second Generation: transistors
Third Generation: integrated circuits
First Generation: vacuum tubes
Explanation:
Generations of computers are categorized based on the technologies that were used in them.
Given innovations or technologies are:
<u>transistors
:</u>
Transistors were introduced in the second generation in place of vacuum tubes.
<u>integrated circuits
:</u>
Integrated circuits were introduced in the third generation. An IC consists of multiple transistors.
<u>vacuum tubes:</u>
The very first generation of computers used vacuum tubes to do the calculations. the only drawback was that the tubes used to heat up very soon.
Hence,
Second Generation: transistors
Third Generation: integrated circuits
First Generation: vacuum tubes
