Answer:
c. h+j+k over 3
Step-by-step explanation:
We know that,
[tex]\text{Average}=\frac{\text{Sum of observations}}{\text{Total number of observation}}[/tex]
Here, h, j and k represents the melting point of helium, hydrogen and Neon respectively,
Since, the sum of melting points = h + j + k,
Also, the total number of gases = 3,
Thus,
[tex]\text{Average melting points}=\frac{h+j+k}{3}[/tex]
Or (h+j+k) over 3
⇒ Option c is correct.
The algebraic expression which shows the average melting
points of helium, hydrogen, and neon is h+j+k over 3.
This is calculated with the sum of the items divided by the
number of items.
In this scenario, we were given the items as h, j and k. The
total number of items is 3.
The average will therefore be = h+j+k/3
