A device that records earthquake activity is placed in a remote part of Africa. The amount of time the device is expected to last has an exponential distribution with mean 5 years. The device will not be monitored for its first three years; after three years, the device will be monitored continuously. Let Y be the point in time at which the device is found to have failed. Find E(Y).

A device that continuously measures and records seismic activity is placed in a remote region. The time, T, to failure of this device has the density function (t) =1%! 0 otherwise Since the device will not be monitored during its first two years of service, the time to discovery of its failure is Xmax (T, 2) Calculate E(X)
1. A device that continuously measures and records seismic activity is placed in a remote region. The time T, failure of the device is exponentially distributed with mean 3 years Since the device will not be monitored during its first two years of service, the time to discovery of its failure is X max(T, 2). Then E(X) - 2. The loss due to fire in a commercial building is modelled by a random variable X with probability density function f(x)-(0.00020-x)...
Earthquake Lab: Locating the Epicenter, Determining the Magnitude, and Calculating the Time of Earthquake The goal of this lab is to learn how seismograms are used to locate the epicenter of earthquakes, determine earthquake magnitudes, and to calculate the origin time of earthquakes. A seismogram measures the amount of shaking caused by earthquake waves. The seismogram first records the arrival of P-Waves (Primary), followed by the arrival of the S-Waves (Secondary). The S-P interval is the time difference between the...
I only need help with part c). Thanks!
As a radioactive specimen decays, its activity decreases exponentially as the number of radioactive atoms diminishes. Some radioactive species have mean lives in the millions (or even billions) of years, so their exponential decay is not readily apparent. On the other hand, many species have mean lives of minutes or hours, for their exponential decay is easily observed. According to the exponential decay law, the number of radioactive atoms that remain after...
14. Spousal Insurance Policies. Consider two alternatives insuring the lives of two part ners: ( individual policies for each spouse paying 2 at each death time (so buy 2 individ- ual policies). (ii) a spousal policy that pays B when the first spouse dies. The present values of () and (i) are zX+2RY and Z2 - Be-r, respectively, where X and Y are the remaining lifetimes of the two insureds (in years), T min(X, Y) is the first death time...
I only need help with part B. I need help with the
sketch and all of B, not just the first part (like others have
answered previously.)
THIS IS THE PART I
REALLY NEED HELP WITH

Read about Cokes strategy in Africa in the article below and discuss the ethics of selling soft drinks to very poor people. Is this an issue that a company like Coke should consider? Africa: Coke's Last Frontier Sales are flat in developed countries. For Coke to keep growing, Africa is it By Duane Stanford Piles of trash are burning outside the Mamakamau Shop in Uthiru, a suburb of Nairobi, Kenya. Sewage trickles by in an open trench.

really appreciate it
Discrete Random Variables Question 23. Let Y Bin(17,0.25) denote the binomially distributed random variable mea- suring the number of times an archer hits the bullseye. Calculate the probability that the archer scores exactly one or two arrows in the bullseye. Question 24. A dairy factory produces eleven buckets of milk and records the masses in kilograms. Compute to three decimal places the population mean and...
Part II: Dana Boar, controller of Digital Electronics Canada, developed the figures requested by her boss and president of Digital Electronics Canada, Hans Fritz. The numbers allowed her to see how the projected sales volume for 2017 related to breakeven, and examine the relative profitability of the two products, DELTA1 and DELTA2. Boar thought the figures were OK as far has her analysis went, but she began to wonder about some of the assumptions built into her calculations. For example,...
