The inverse

Replace f(n) with y

Swap positions of y and n

Make y the subject

Replace y with f'(n)

= 856

Answer:h = y^2 / 27
Step-by-step explanation:
Volume of a cylinder = pi*(xx)^2*yy
= x^4*pi*yy
Volume of a cone = 1/3*pi*(9x^2)^2*h
= 27pi*x^4*h
x^4*pi*y^2 = 27pi*x^4*h
h = y^2 / 27
Find median, in this group median is 1
find Q1 which is median of lower half, in this group Q1 = 1/4
find Q3, which is median of upper half, in this group Q3 = 5/4
IQR is Q3-Q1
IQR = 5/4 - 1/4 = 4/4 = 1
The answer would be 80. You would do 44 times 100, then divide by 55.
