The authors of the article "a probabilistic insulation life model for combined thermal-electrical stresses" (ieee trans. on elect. insulation, 1985: 519ā522) state that "the weibull distribution is widely used in statistical problems relating to aging of solid insulating materials subjected to aging and stress." they propose the use of the distribution as a model for time (in hours) to failure of solid insulating specimens subjected to ac voltage. the values of the parameters depend on the voltage and temperature; suppose and (values suggested by data in the article).a. what is the probability that a specimenās lifetime is at most 250? less than 250? more than 300? b. what is the probability that a specimenās lifetime is between 100 and 250? c. what value is such that exactly 50% of all specimens have lifetimes exceeding that value? in r language

If mā abc = 70Ā°, what is mā abd? justify your reasoning. using the addition property of equality, 40 + 70 = 110, so mā abd = 110Ā°. using the subtraction property of equality, 70 ā 30 = 40, so mā abd = 30Ā°. using the angle addition postulate, 40 + mā abd = 70. so, mā abd = 30Ā° using the subtraction property of equality. using the angle addition postulate, 40 + 70 = mā abd. so, mā abd = 110Ā° using the addition property of equality.
