The Weibull density function is given by f(y) = 1 αmym−1 exp(−y m/α), y > 0, 0, otherwise. where α and m are positive constants. This density function is often used as a model for the lengths of life of physical systems. Suppose Y has the Weibull density just given. Find a. the density function of U = Y m . b. E Y k for any positive integer k .

attached below is the answer and detailed solution

Step-by-step explanation:

A) find the density function  U = Y^m

attached below is the detailed solution

B) Find E () for any positive integer k .

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
