Let X denote the distance (m) that an animal moves from its birth site to the first territorial vacancy it encounters. Suppose that for banner-tailed kangaroo rats, X has an exponential distribution with parameter λ = 0.01362.

(a) What is the probability that the distance is at most 100 m?

(b) What is the probability that distance exceeds the mean distance by more than 2 standard deviations?

(c) What is the value of the median distance? (Round your answer to two decimal places.)

A car moves along an x axis through a distance of 980 m, starting at rest (at x = 0) and ending at rest (at x = 980 m). Through the first 1/4 of that distance, its acceleration is +3.00 m/s2. Through the next 3/4 of that distance, its acceleration is -1.00 m/s2. What are (a) its travel time through the 980 m and (b) its maximum speed?

Will Smith consumes chocolate and milk. Let y denote chocolate and x denote milk. Chocolate has an unusual market where there is only one supplier, and the more chocolate you buy from the supplier, the higher the price she charges per unit. In fact, y units of chocolate will cost Will y2 dollars. Milk is sold in the usual way at a price of 2 dollars per unit. Will’s income is 20 dollars and his utility function is U =...

Let the random variable X denote the time (hours) for which a part is waiting for the beginning of the inspection process since its arrival at the inspection station, and let Y denote the time (hours) until the inspection process is completed since its arrival at the inspection station. Since both X and Y measure the time since the arrival of the part at the inspection station, always X < Y is true. The joint probability density function for X...

Two fair dice are rolled at once. Let x denote the difference in the number of dots that appear on the top faces of the two dice. For example, if a 1 and a 5 are rolled, the difference is 5−1=4, so x=4. If two sixes are rolled, 6−6=0, so x=0. Construct the probability distribution for x. Arrange x in increasing order and write the probabilities P(x) as simplified fractions.
