Arrange the numbers in order from smallest to largest:
12, 18 , 25, 26 , 30, 31 , 34
Find the highest and lowest numbers, those would be where the black dots go on the number line.
Lowest number = 12
Highest number = 34
The line inside the box would be the Median number of the set.
Find the median ( middle value):
Since there is an odd amount of numbers the median would be the middle number:
Middle number = 26
The graph that has the black dots on 12 and 34 and the line of 26 is the first one
General Idea:
In any right triangle,
1. The altitude to the hypotenuse is the geometric mean between the segments into which is separates the hypotenuse.
2. Each leg is a geometric mean of the hypotenuse and the segment of the hypotenuse adjacent of the leg.
Applying the concept:
Step 1: We need to label the given diagram and set up a proportion by comparing the similar triangles as provided in attached figure.
Setting up the proportion, we get...

Conclusion:

Answer:
Some ordered pairs could be (0,2) and (2,3).

Answer:
The value of y is 0.25
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form
or 
For x=5
Find the value of y
k=1.25
substitute in the equation
