Which explains whether or not the function represents a direct variation?

The function represents a direct variation

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form or

In a linear direct variation the line passes through the origin and the constant of proportionality k is equal to the slope m

Let

------> the line passes through the origin

Find the value of k------> substitute the value of x and y

----->

Find the value of k------> substitute the value of x and y

----->

Find the value of k------> substitute the value of x and y

----->

Find the value of k------> substitute the value of x and y

----->

The value of k is equal in all the points of the table and the line passes through the origin

therefore

The function represents a direct variation

the equation of the direct variation is equal to

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all
