A vacuum manufacturer runs tests on a feature that prevents overheating in its machines and finds that the range of failure rates is 18% and the mean failure rate is 17%. Should the manufacturer recall the machines already sold? Yes, because there is a high range of failure. Yes, because there is a high failure rate and range. No, because there is a low mean failure rate. Maybe, depending on the sample size.

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.

.there can be infinite values of m and n that can satisfy the above equation. for each value of m of m or n. there maybe infinite sets of solution for the above
