Hey there! I'll try to provide you with my best answer.

51.198 but if the question asks approximation then it's 51 .

In order to find we the mean, we add them all and divide the total by how many numbers there were. So,

(41 + 39 + 48 + 52 + 46 + 62 + 54 + 40 + 96 + 52.98 + 40 + 42 + 52.60)/13

= 665.58/13

= 51.198

Approximately its 51

Hope it helps! ^^

the height of the surface increases from the center out to the sides of the road.

step-by-step explanation:

as we move out we move away from the x-axis.

and as mentioned in the problem statement that height of a road increases when we move away from the center x.

hence proved that 3rd option

the height of the surface increases from the center out to the sides of the road.

is the correct option.
