Sammy is in 4th grade. he came home from school very confused regarding something his math teacher told him. his teacher said that the fraction latex: \frac{1}{x}1 x becomes smaller as x becomes larger. sammy thought differently. it seemed to him that since x was getting larger, then latex: \frac{1}{x}1 x should be getting larger too. develop this mathematics from sammy's 4th grade conversation to your study and practice of limits. do so as collaboratively as you can, with each of you participating by either inserting ideas or challenging those of others as you tell the story. what other questions, like sammy's, could you include in this expose?

Merrida uses a pattern in the multiplication table below to find ratios that are equivalent to 7: 9. if merrida multiplies the first term, 7, by a factor of 6, what should she do to find the other term for the equivalent ratio? multiply 9 by 1. multiply 9 by 6. multiply 9 by 7. multiply 9 by 9.

What is the inverse of f(x) = 6x -24

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
