Which artist was least successful in his lifetime? Rembrandt, De la Tour, Rubeens, or Vermeer?I think it was Vermeer.

- 2Pick two similar small businesses in the same industry with which you are familiar, one successful and one not so successful
Pick two similar small businesses in the same industry with which you are familiar, one successful and one not so successful. Describe them in a post, and compare and contrast these businesses. What is the difference in management style between the two businesses?What is the difference in marketing strategy? What changes would you suggest to the less successful business?

The lifetime y (in hours) of the central processing unit of a certain type of microcomputer is an exponential random variable with parameter β = 207. Find the varianceof the lifetime of the central processing unit.

- 5Ozone Lifetime
Consider these two ozone depleting compounds, and their respective ozone depletion potentials (ODP): CHFCl2 (ODP = 0.04) C2H3FCl2 (ODP = 0.11) Which molecule has theshorter lifetime in the troposphere: CHFCl2 or C2H3FCl2? In the tropics, strong convection facilitates rapid vertical transport of air from the surface to high in thetroposphere. Explain how this affects the “true” (as opposed to estimated) ozone depleting potential of any given compound emitted in the tropics compared to emissionsof that same compound in the mid- or high- latitudes.

- 7determining lifetime
the following reaction:O3--hv----->O(1 D) + O2 (1 Δ g )for a wavelength threshold of310 nm. The excited oxygen atom is quickly quenched by either nitrogen or oxygen. The rate constant for quenching with air is given by:k0(1D)+M =1.8 * 10-11 e110k/T(cm3 /molecules)where T is in KelvinDetermine the lifetime, τ= (1/k[M]) at 220k for quenching with air.

- 10Distance and lifetime of a particle?
The average life time of a particle in its ownframe of reference or proper lifetime is 3.9x10-8s. If the particlemoves with a speed of 0.82c,a) What is the mean lifetime as measured by a person on Earth?b) What is the distance the particle travels as measured onEarth?c) What would the distance the particle would travel if timedilation did not occur?After reading the chapter on this I am not sure what formulas touse, can someone lead me in the right direction?

Average current is 5.6 A for a pacemaker supplying 0.42A-h of charge. I found the charge the battery can supply is 1512 Coulombs, but how do I determine expectedlifetime of device?

- 12Heelp please - lifetime of a system
Suppose that a system consists of n components in series and that the ith component has a failure time that can be modeled by an exponentil distribution with meantime to failure μ. Thus, the failure time of each component, Xi, exponential with parameters λi = 1/μi. The system is still working at time t iff all of the ncomponents are still working.2. Suppose a system relied on n batteries each with mean time to failure μ. What would be the mean time to failure of the system?(Note: Recall that for X follows EXP(λ) we have f(t) = λe-λt and F(t) = 1-e-λt for t>0 thus the reliability function is r(t) = 1-F(t) = e-λt.)
