Answer:
B. Linear relationship
IQR is 4, median is 58.
Step-by-step explanation:
Enter these values in a list, hit stat > calc > 1-var stats. That gives you the 5 number summary. To get IQR, subtract Q3 from Q1.
Car 1: 15x
Car 2: 20y
15x+20y=1300
x+y=75
So y=75-x
15x+20(75-x)=1300
-5x+1500=1300
-5x=-200
x=40.
y=75-40
y=35
Car 1: 40 gallons
Car 2: 35 gallons
