Answer:
1.) Relative cell reference - A1
2.) Absolute cell reference - $D$2
3.) Mixed cel reference - $D2
Explanation:
In Microsoft Excel, cell references are very important and critical when dealing with formula. They can give you what you’re looking for or make your entire worksheet incorrect.
A cell reference is a cell address or a range of cell addresses that can be used in a formula.
There are three types of cell references and they are;
a) Relative reference
b) Absolute reference
c) Mixed reference
A relative cell reference is a cell reference that changes when you copy the formula to other cells. It s usually just a normal cell reference like A1, B2, C3. If a formula with a relative cell reference is copied down to other cells, the formula will change. That is a formula with a relative cell reference changes with respect to the cell which it is copied to.
An absolute reference does not change when you copy the formula to other cells. In absolute references, the dollar sign $ is used to “lock” both the row and column so that it does not change when it is copied to other cells. An example is $D$2.
Using a mixed cell reference, one is trying to see that only either the row or column changes with respect to other cells when they are copied. It is like “locking” either the column or the row while changing the other. Just like from the example, $D2 is a mixed cell reference where only the column is locked such that only the row changes when the formula is copied to other cells.
The light bulb is important because it helps you see in the dark.
The light bulb is a round object that produces light from energy.
People can't live without the light bulb because it helps you out a lot such as see in the dark like when you do homework at night.
It could help businesses profit because many will want to buy it cause they can be cheap but many will sell and it could help you a lot!
The answer to that is a Pixel
Answer:
168 (although the =< must be corrected to <=)
Explanation:
int count = 0;
for (int row = 4; row <= 15; row++)
for (int col = 0; col < 13; col = col +2)
count+=2;
The inner for loop runs 7 times (for col = 0,2,4,6,8,10,12). Anything higher is not less than 13. Therefore the inner loop increments count by 2 seven times, i.e. it increments count by 14.
The outer for loop runs 12 times (for row = 4,5,6,7,8,9,10,11,12,13,14,15).
If the count is incremented by 14 twelve times, you are incrementing it by 14*12 = 168.
Therefore the count goes from 0 to 168 after the nested loops.
D. All of these
Reason being, they wouldn't have been made if something hasn't been discovered about them.
