President Thomas Jefferson sent Lewis and Clark into the newly acquired Louisiana Territory primarily to
(1) Explore and map the region
(2) Search for gold and other valuable mineral deposits
(3) Improve relations with Native American Indians
(4) Force British and Spanish settlers out of the territory

I think the answer is (1) Explore and map the region

what are the events? you didnt list any

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.

hope this !
