Answer:
b.12.25
Step-by-step explanation:
You just simply divide 220.50 by 18 and you will end up with the rate per hour.
Each is 30° because you do 90/3 is 30
Answer:
It's steepness decreases
Step-by-step explanation:
If you graph both, you can see it's less steep. Sorry I don't know if there's any other faster way.
So when one goes up, the other goes down. This is an inverse equation.
An inverse equation looks like this: y = 1/x
In this case, when parking fee (f) decreases, cars (c) increase.
You know which side to put each variable on using the chart they gave you.
f | c
20.00 15 (20.00 = x/15) x=300
30.00 10 (30.00 = x/10) x=300
So your equation in this case is f = 300/c
Knowing that, plug in the fee of 6.00
6 = 300/c Multiply both sides by c.
6c = 300 Divide both sides by 6.
c = 50 cars
It would be 53%. The biased survey is survey 2. The other surveys give 50%, 54%, and 54%
