- Use the table of values you made in part 4 of the example to find the limiting value of the average rate of change in velocity.we investigate if a period of time feels longer or shorter when people are bored compacted to when they are not bored. using independent samples, we obtain these estimates of the time period (in minutes) sample 1 (bored) xbar= 14.5 s2x= 10.22 n= 28 sample 2(not bored) xbar=9.0 s2x=14.6 n=34 (a) what are Ho and Ha? (b) compute t-obt (c) with alpha =.05, what is t-crit?A CI is desired for the true average stray-load loss ? (watts) for a certain type of induction motor when the line current is held at 10 amps for a speed of 1500 rpm. Assume that stray-load loss is normally distributed with ? = 2.1. (Round your answers to two decimal places.)

D4 is 1,916 and alpha and beta values are 0.4, and 0.53, respectively. The error for the forecast in period 4 (F4) is:Let {X(t)} be a geometric BM with standard deviation parameter σand drift parameter µ . Find E(X(t)).

(Show solution)Suppose that a particle moves along a coordinate line so that its velocity at time t is v(t) = 2 cos t. Find the average velocity of the particle during the time interval 0 =< t =< pi.Suppose the lengths of human pregnancies are normally distributed with u = 266 days and 0 = 16 days. The figure to the right represents the normal curve with u = 266 days and 0 = 16 days. The area to the left of X = 245 is 0.0947. Provide two interpretations of this area.

Accordingly, find the temperature distribution up to j=3 using the Explicit method. (α=0.9 cm2/s)A multiple cascade is shown in Fig. 1.5.6. At time t D 0,tank 0 contains 1 gal of ethanol and 1 gal of water; all theremaining tanks contain 2 gal of pure water each. Purewater is pumped into tank 0 at 1 gal=min, and the varying mixture in each tank is pumped into the one below itat the same rate. Assume, as usual, that the mixtures arekept perfectly uniform by stirring. Let xn.t / denote theamount of ethanol in tank n at time t.
