Estimate the median of the distribution of drinks.
Hint: Think about the 50th percentile.

25 grams

Step-by-step explanation:

The relative cumulative frequency gives us an equivalent of the percentiles of the distribution.

Thus, percentile is equivalent to a relative cumulative frequency of 0.5.

The median is roughly the 50th percentile, which is a cumulative frequency of 0.5.

From the graph, the grams of sugar on the x-axis that corresponds to a cumulative frequency of 0.5 on the y-axis, is 25 grams.

Therefore, the median is 25 grams.

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.

25% is the answer
