Question

Which is the constant of proportionality for the data in the table?

Answer 1

Answer:

C) 6

Step-by-step explanation:

From the given data we can find the constant of proportionality by dividing The number of people by number of cars.

Constant of proportionality = $\frac{\textrm{Number of people}}{\textrm{Number of cars}}$

Taking any point from the table will give the same constant of proportionality as they are proportional quantities.

Constant of proportionality = $\frac{18}{3}=\frac{30}{5}=\frac{36}{6}=\frac{48}{8}=6$

This can be written as 6 people per car.

For 10 cars, number of people will be =$10\times 6$=60 people.
