4. The Old Towne Road Group sent its' top specialist, Tegan (aka Stat Buddees) to get information on why the Street Farmacyst plastic bottles did not explode under pressure. They selected 36 Street Farmacyst bottles and got a mean of twenty-six with a population standard deviation of 1.5. a. What is the maximum error? ( (2pt.) b. Help her construct an 80% confidence interval for the mean number of plastic bottles that did not explode under pressure. (3pts)

Apply the forcing function v(t) 60e−2t cos(4t + 10°) V to the RLC circuit in series of Figure 14.1 and specify the forced response by determining the values of Im and φ in the expression i(t) Ime−2t cos(4t + φ) in the domain of time

A car averages 27 miles per gallon. If gas costs $4.04 per gallon, which of the following is closest to how much the gas would cost for this car to travel 2,727 typical miles?

A 263-gram block is dropped on a vertical spring with a constant force a = 2.52 N / cm (Figure 20). The block sticks to the resource, and the resource is compressed 11.8 cm before momentarily coming to rest. While the resource is being compressed, how much work is done on (a) the force of gravity and (b) the resource? (c) What was the speed of the block immediately before it reached the resource? (d) If this initial velocity of the block is doubled, what is the maximum compression of the spring?
