In the following activity, write an equation to represent each verbal statement, and use it to find the value of each unknown number. then, put the solution values in order from smallest to largest. [note: the smallest solution is "first", and the largest solution is "fifth".]

the sum of a number and two is equal to the quotient of six and negative four.

the difference between four times a number and five has a result of negative eight.

half of a number is added to four. this sum is equivalent to negative one.

the sum of a number and three is divided by five. the result is negative two.

the difference between a number and five is multiplied by negative two. the resulting product equals fourteen.

look how many points this question is !

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
