Question

Which algebraic expression shows the average melting points of helium, hydrogen, and neon if h represents the melting point of helium, j represents the melting point of hydrogen, and k represents the melting point of neon?

Answer 1

Given:
h = melting point of helium
j =  melting point of hydrogen
k = melting point of neon

Number of values = 3
Therefore, the average is
(Sum of values)/(Number of values) = (h+j+k)/3

Answer:
The average melting point of helium, hydrogen, and neon is
(h+j+k)/3
