Suppose the x-axis of a density graph represents someone's age in years. If the area under the density graph from 10 years to 70 years is 0.85, what is the probability of someone's age being anywhere from 10 years to 70 years?

take it another

where is the gragh

step-by-step explanation:

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.
