The average cost represents the slope of the line of the graph.
Increasing the slope of the graph increases the steepness of the line.
Therefore, increasing the average cost of gas from $1.50 to $2.20 will increases the steepness of the line. (i.e. the line becomes closer to the vertical line).
Twice as much time. So it would be 36 minutes.
P(x)=n!/(n-x)!x!= 15!/12!*3!
P(x)=15*14*13*12!/12!*3*2*1=455
Answer:
=
Step-by-step explanation:
You want to match up the sides for this one.
The first answer would be incorrect because the sides aren't the same from the bigger on to the smaller.
The second answer would be incorrect because the first one goes from the bigger figure to the smaller one but on the other side of the equal sign goes from the smaller figure to the bigger figure.
I can't see the denominators on the third one but if its:
=
then thats correct because it matches all the sides
