Answer:
600/mph
Step-by-step explanation:
The answer to the question
The diagonals of the parallelogram are congruent.
The sample correlation coefficient r is equal to 0.9962
<span>The linear correlation coefficient is positive. -1 </span>≤ r ≤ + 1.
0.9962 is nearer to +1. Thus, the linear correlation is positive.

Let's call the fuel consumption of the first car "x" and the second car "y"
x + y = 35 is the total fuel consumed.
20x + 25y = 775 is the distance traveled.
Solve the two equations. Skipping a few steps, I get
5y = 75. Therefore y = 15. So y used 15 gallons of gas. Therefore x used 20 gallons.
20 gallons, 15 gallons.
