A CI is desired for the true average stray-load loss μ(watts) for a certain type of induction motor whenthe line current is held at 10 amps for a speed of 1500rpm. Assume that stray-load loss is normallydistributed with o = 3.0.a. Compute a 95% CI for μ when n = 25 andнx = 58.3.b. Compute a 95% CI for μ when n = 100 andx = 58.3.

A stone is tossed into the air from ground level with an initial velocity of 35 m/s. Its height at time t is h(t) = 35t – 4.9t2 m. Compute the stone's average velocity ī in m/s over the time intervals [1, 1.01], [1, 1.001], [1, 1.0001] and [0.9999, 1], [0.999, 1], [0.99, 1]. (Use decimal notation.

A rocket will carry a communications satellite into low Earth orbit. Suppose that the thrust during the first 200 sec of fligh is provided by solid rocket boosters at different points during liftoff. The graph shows the acceleration in G-forces (that is acceleration in 9.8-m/sec2 increments) versus time after launch. a. Approximate the interval(s) over which the acceleration is increasing. b. Approximate the interval(s) over which the acceleration is decreasing. c. How many turning points does the graph show? d. Based on the number of turning points, what is the minimum degree of a polynomial function that could be used to model acceleration versus time? Would the leading coefficient be positive or negative? e. Approximate the time when the acceleration was the greatest. f. Approximate the value of the maximum acceleration.
