An important factor in solid missile fuel is the particle size distribution. significant problems occur if the particle sizes ar
e too large. from production data in the past, it has been determined that the particle size (in micrometers) distribution is characterized by f(x) = 3x−4, x> 1, 0, elsewhere. (a) verify that this is a valid density function. (b) evaluate f(x). (c) what is the probability that a random particle from the manufactured fuel exceeds 4 micrometers?
For this question you should know that: 2/3 = 8/12 and 3/4 = 9/12 so now you can say: 7/12 < 8/12 < 9/12 so: 7/12 < 2/3 < 3/4 :))) i hope this is helpful have a nice day
