Explain why the equation 6|x| + 25 = 15 has no solution. when one solves, they arrive at a step where |x| is equal to a negative number. since | x| can never be negative, there is no solution. when one solves, they arrive at a step where x is equal to a negative number. since x can never be negative inside of the absolute value bars, there is no solution. the statement is false. there is a solution. when one solves, they arrive at a step where |x| is equal to a fraction that may not be represented as an integer. since | x| must be an integer, there is no solution.

The weibull distribution is widely used in statistical problems relating to aging of solid insulating materials subjected to aging and stress. use this 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 α = 2.5 and β = 190. (a) what is the probability that a specimen's lifetime is at most 250? less than 250? more than 300? (round your answers to four decimal places.) at most 250 less than 250 more than 300 (b) what is the probability that a specimen's lifetime is between 100 and 250? (round your answer to four decimal places.) (c) what value is such that exactly 50% of all specimens have lifetimes exceeding that value? (round your answer to three decimal places.) hr
