Answer:

The pair of variables that show a clear causal link are the number of lights switched on in a room and the room's brightness

Step-by-step explanation:

Clear casual link indicates two variables that have a completly and unequivocal relation, meaning that changes in one variable produce automatically and with no doubt a change in the other.

Case A does not have this link as these two variables have no relation at all. A person from certian state may have any type of academic degree.

Case B Cost of aviation fuel may be explained by other variables like international prices and flight duration may be explained also due to climate.

Case D- a person may have a pet even under low income levels.

Case C is the only adequate relation, as turning lights on will always increase room's brightness.

Answer: 1

Scotland

Step-by-step explanation:

In the first vote, points are:

France = 15

England = 12 + 16 = 28

Ireland = 19

2nd vote

England = 15

Scotland = 12 + 19 = 31

Ireland = 16

3rd vote

Scotland = 15 + 16 = 31

Ireland = 12

England = 19

4th vote

Ireland = 15

France = 12 + 16 + 19 = 47

At the end of everything

England = 19 + 15 + 28 = 62

France = 15 + 47 = 62

Scotland = 31 + 31 = 62

Ireland = 19 + 16 + 12 + 15 = 62

To find the Condorcet winner, the number of votes for runner over opponent (runner,opponent) is compared with the number of votes for opponent over runner (opponent,runner)

Only Scotland has the highest (31) points twice.

If you want to place an 8 ½ inch towel bar in the center of a door that is 25 ½ wide, how much space will be on each side of the

Marta_Voda [28]

Answer:

8 $\frac{1}{2}$ in on each side

Step-by-step explanation:

If a door is 25 $\frac{1}{2}$ in wide and the towel bar is 8 $\frac{1}{2}$ in long, we can first subtract the length of the towel bar from the total width of the door to find out how many inches of space are remaining:

25 $\frac{1}{2}$ - 8 $\frac{1}{2}$ = 17

Since you want to center the towel bar on the door, you can divide the remaining space by two (2) to find how much space will be on each side:

17/2 = 8.5 inches on each side.
