<h2>The Third table of ordered pairs represents a proportional relationship. </h2>

Explanation:

A proportional relationship is defined as the relationship between two quantities where one is directly proportional to another with a proportionality constant.  

For example, y = ax

Here a is the proportionality constant.  

This expression shows that y varies directly as x varies.  

From the tables mentioned in the below attachment, we can easily say that "Table 3" has the ordered pairs which represents proportional relationship.

Table 3 defines y is directly proportional to x with proportionality constant \frac{1}{7}.

tatiyna

Answer:

70 cars  per year.

Step-by-step explanation:

Given:

In 1984 a locally-owned car company sold 2,743 cars.

In 2003, the car sales rose to 4,069.

Question asked:

What was the average rate of change for the total number of cars sold?

Solution:

In 2003 number of cars sold = 4069

In 1984 number of cars sold = 2743

Change in the number of car sold = 4069 - 2743

                                                         = 1326

Now, time interval between 2003 and 1984 = 19

The\ average\ rate\ of\ change=\frac{Change\ in\ the\ number\ of\ car\ sold}{Time \ interval}

                                             =\frac{1326}{19} \\=69.789\\\\=70\ cars\ per\ year\  (approx)

Thus, the average rate of change for the total number of cars sold is 70 cars  per year.

Scott: 200/10 ft^2/hr

So together: 200 / (200/14 + 200/10) = 5.83 hours
