Arranging the given data in ascending order:
1, 2, 2, 3, 3, 4, 7, 7, 7, 9
Meadian is the middle-most observation.
i.e. The Median here is average of 3 and 4.
= (3+4)/2
= 7/2
=3.5
Hope it helps...

The initial amount of the water is 15 gallons
<h3>Linear functions</h3>
These are functions that has a leading degree of 1. Given the equation that represents the amount of water remaining after x minutes;
y - 12 = -3(x- 1)
y -12 = -3x + 3
y = -3x +3 + 12
y = -3x + 15
In order to determine the initial amount of water, we will substitute x =0 into the function
y = -3(0) + 15
y = 15
Hence the initial amount of the water is 15 gallons

Answer:
x = 5
Step-by-step explanation:
x + 1 = 6. subtract the given numbers
(5) + 1 = 6. find the solution (x)
