A mechanical engineer wishes to compare strength properties of steel beams with similar beams made with a particular
alloy. The same number of beams, n, of each type will be
tested. Each beam will be set in a horizontal position with a
support on each end, a force of 2500 lb will be applied at the
center, and the deflection will be measured. From past experience
with such beams, the engineer is willing to assume
that the true standard deviation of deflection for both types
of beam is .05 in. Because the alloy is more expensive, the
engineer wishes to test at level .01 whether it has smaller
average deflection than the steel beam.

An airplane consumes fuel at a constant rate while flying through clear skies, and it consumes fuel at a rate of 64 gallons per minute while flying through rain clouds. let c represent the number of minutes the plane can fly through clear skies and r represent the number of minutes the plane can fly through rain clouds without consuming all of its fuel. 56c+64r < 900056c+64r< 9000 according to the inequality, at what rate does the airplane consume fuel while flying through clear skies, and how much fuel does it have before takeoff? the airplane consumes fuel at a rate of gallons per minute while flying through clear skies, and it has gallons of fuel before takeoff. does the airplane have enough fuel to fly for 60 minutes through clear skies and 90 minutes through rain clouds?
