Let Y = X? , with X ? Expo(1) and ? > 0. The distribution of Y is called the Weibull distribution with parameter ?. This generalizes the Exponential, allowing for non-constant hazard functions. Weibull distributions are widely used in statistics, engineering, and survival analysis; there is even an 800-page book devoted to this distribution: The Weibull Distribution: A Handbook by Horst Rinne. For this problem, let ? = 3.(a) Find P(Y > s + t|Y > s) for s, t > 0. Does Y have the memoryless property?(b) Find the mean and variance of Y , and the nth moment E(Y n ) for n = 1, 2, . . . .(c) Determine whether or not the MGF of Y exists.

3a-24=0

step-by-step explanation:

let's assume

number of candles set =x

price of of x candles =p(x)

we are given

a candle maker prices one set of scented candles at $10 and sells an average of 200 sets each week

so, we get point as (200,10)

he finds that when he reduces the price by $1, he then sells 50 more candle sets each week

so, we can find slope

now, we can use point slope form of line

now, we can plug values

we can use point

and find b

now, we can plug it back

and we get

now, we can find revenue

we know that

revenue = price*quantity

so, we get
