Question

# The breaking strength X of a concrete slab has a density function

f(x)=

Ae^{(-x/100)}dx

for breaking strength values in the range, 120 ≤ x ≤ 150.

a) Calculate the value of the constant A.

b) Plot the distribution in Maple (must show your code and output).

c) What is the probability that the concrete slab has a breaking strength between 130 and 150?

d) Find the average breaking strength.

e) Find the 80^{th} percentile breaking strength.
