Explain the purpose of a supply curve.

A supply curve provides a reader, student, or policy maker with a visual representation of the relationship between the price and quantify of a product, as it relates to what the supplier is willing to sell it for and how much they are willing to sell.

the median of the data is 4.

step-by-step explanation:

the median means the middle number of a given number.

to decide which one is the median, arrange in ascending or descending order. but sometimes, you may find two(2) number in the middle, but it's easy, just add them together and divide by 2.

so,   determine the median of the data. 2, 3, 3, 4, 5, 7, 9

it is already arranged, count 3 times forward and 3 backward and the one left is your answer.

2,3,3,4,5,7,9

our answer is 4.
