Delaware has three counties: Kent, New Castle, and Sussex. Let X1 be the number of years until a flood hits Kent County, X2 be the number of years until a flood hits New Castle County, and X3 be the number of years until a flood hits Sussex County. Assume X1, X2, and X3 are independent and that they are exponentially distributed with the following arrival rates per year: County
1. Kent 0.8
2. New Castle 1.2
3. Sussex 0.7
What is the probability that the first flood to arrive in Delaware will be in Sussex County?
Determine whether each distribution below is discrete or continuous:
Normal
Exponential
Uniform
Binomial
Student-t
F
Poisson
Let X be exponentially distributed with an arrival rate of 0.5. What is P(X<2)?

The boiling point of water at an elevation of 0 feet is 212 degrees fahrenheit (°f). for every 1,000 feet of increase in elevation, the boiling point of water decreases by about 2°f. which of the following represents this relationship if b is the boiling point of water at an elevation of e thousand feet? a) e = 2b - 212 b) b = 2e - 212 c) e = -2b + 212 d) b = -2e + 212

Gexpressions: practice question 3 of 5 jackson wants to study the popularity of his music video by tracking the number of views the video gets on his website. the expression below represents the total number of views that jackson's video receives n days after he begins tracking the nu views, where b is the rate at which the number of views changes. alb)" select the statement that would accurately describe the effect of tripling a, the initial number of views before jackson beginst the rate at which the number of views changes, b, will triple. the total number of views the video has after n days, a(b)", will not change. the total number of days since jackson begins tracking views, n, will be reduced by one-third. the total number of views the video has after n days, alb)", will triple. submit
