Which exponential function has an initial value of 2? f(x) = 2(3x) f(x) = 3(2x)

If f(x)=-3x+2 and g(x)=-7x-2, which point represents f(x)=g(x)?

The life (in hours) of a magnetic resonance imagining machine (mri) is modeled by a weibull distribution with parameters β = 2 and δ = 370 hours. (a) determine the mean life of the mri. (round your answer to 2 decimal ) determine the variance of the life of the mri. (round your answer to 1 decimal ) what is the probability that the mri fails before 250 hours? (round your answer to 4 decimal places.)
