According to the world health organization (who), body mass index (bmi) is a statistic that indicates the ratio of a person's weight to their body volume. the centers for disease control (cdc) uses the table below to classify children from ages 2 to 20. because bmi values change as children grow, the cdc uses percentiles rather than fixed values for bmi. percentiles provide a basis of comparison for bmi over time.
based on data from who, a representative sample of 11-year-old males could consist of the following 15 values.
15.7,16.0,13.9,15.3,18.6,14.8,17.7, 16.6,18.1,19.2,16.3,17.3,16.9,25.6, 20.4
using this data, calculate the 85th percentile. give your answer precise to one decimal place.
85th percentile =

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3
