Anew centrifugal pump is being considered for an application involving the pumping of ammonia. the specification is that the flow rate be more than 5 gallons per minute (gpm). in an initial study, eight runs were made. the average flow rate was 6.5 gpm and the standard deviation was 1.9 gpm. if the mean flow rate is found to meet the specification, the pump will be put into service. 1. state the appropriate null and alternate hypotheses

2. find the p-value

3. should the pump be put into service? explain.

Polygons efgh and e′f′g′h′ are shown on the coordinate grid: what set of transformations is performed on efgh to form e′f′g′h′? a. a translation 1 unit to the left followed by a 90-degree counterclockwise rotation about the origin b. a translation 1 unit to the right followed by a 90-degree counterclockwise rotation about the origin c. a 90-degree clockwise rotation about the origin followed by a translation 2 units to the right d. a 90-degree clockwise rotation about the origin followed by a translation 2 units to the left

21 type the correct answer in the box. use numerals instead of words. if necessary, use / for the fraction bar. the solution set of n2 - 14n = -45 is { (separate the solutions with a comma)

Raymond just got done jumping at super bounce trampoline center. the total cost of his session was $43.25 . he had to pay a $7 entrance fee and $1.25 for every minute he was on the trampoline. write an equation to determine the number of minutes (t) that raymond was on the trampoline.
