Think about a density curve that consists of two line segments. The first goes from the point (0, 1) to the point (0.1, 1). The second goes from (0.1, 1) to (0.7, 2) in the xy-plane. What percent of observations fall below 0.05?

It would be helpful for you if you quickly draw out the curve following the instructions in the question. Second thing is that if you calculate the area under the graph you will get 1 as you should since this is a density curve. Since the overall function/graph is normalized that is the area under it is 1 then all we need to do is to calculate the area under the graph from x=0 to x=0.05 to obtain the fraction of the observations that will be equal or below x=0.05 and then multiply this number by 100 to conveniently convert it to a percentage like (0.05*1)*100% = 5%, the part in the bracket (0.05*1 = 0.05) is the area under the curve.

Percentage of population below 0.05 = 5%, when calculated using coordinates.

WHAT IS THE DENSITY CURVE?

A density curve is the graph of a continuous distribution.

Total area under graph(attached)= 0.1*1 + 1*(0.7-0.1) + 1*0.6/2 = 1

Area below 0.05 = 1*0.05=0.05

So, percentage of population below 0.05 = (0.05/1) *100 = 5%

Therefore, percentage of population below 0.05 = 5%
