y + 6 = 2(x − 4)

Option B:
y − 6 = 2(x + 4)

Option C:
y + 1 = −2(x − 14)

Option D:
y − 1 = −2(x + 14)

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.)
