A parabolic satellite dish reflects signals to the dish's focal point. An antenna designer analyzed signals transmitted to a satellite dish and obtained the probability density function f(x)= c(1- 1/16x^2) for 0
a. Value of c that makes f(x) a valid probability density function.
b. P(X<=0.4)=
c. P(0.1 < x <0.4)=

Step-by-step explanation:

given that a parabolic satellite dish reflects signals to the dish's focal point. An antenna designer analyzed signals transmitted to a satellite dish and obtained the probability density function

For f(x) to be a pdf total prob = 1

i.e.

b)

c) P(0.1<x<0.4) =

the answer to the question is a  

it has the same slope and the same y-intercept.
