The probability $p$ of getting a head when flipping the coin once is estimated by $n$ $\hat{p} = \frac{1}{n} \sum_{i=1}^{n} X_i$, where $X_i = \begin{cases} 1, & \text{if head occurs in the } i\text{th flip} \\ 0, & \text{otherwise} \end{cases}$ Show that $\frac{\hat{p}(1-\hat{p})}{n-1}$ is an unbiased estimator of Var($\hat{p}$).

Given the unity feedback system shown below with $G(s) = \frac{K}{(s+2)(s+4)(s+6)(s+8)}$ Find the transfer function of a lag-lead compensator that will yield a settling time 0.5 second shorter than that of the uncompensated system, with a damping ratio of 0.5, and improve the steady-state error by a factor of 30. The compensator zero is at '-5'. Also, find the compensated system's gain. Justify the second-order approximations and verify the design through MATLAB simulation. NOTE: Use MATLAB to find the dominant poles for the uncompensated system. ***** END OF QUESTION *****

A cylindrical tank is being filled with water. The tank is initially empty but then water begins to flow into it at a rate of 74.00 kg/min. There is a small hole of radius r = 0.6000 cm at the bottom of the tank where water can escape. Because the flow rate of water leaving the hole is initially at a slower rate than water entering the tank, the water level rises. The average velocity of water leaving through the hole at the bottom of the tank is not constant and is a function of the height of the water level in the tank: v = \sqrt{2gh} where g is the gravitational constant of Earth, 9.81 m/s². Additionally, the density of water at this temperature is 1.000 \times 10^3 kg/m³. What is the maximum height of the water level in the tank, if it is initially empty? Number h = 6.03 m If the radius of the tank is R = 0.3500 m, how long will it take the tank to reach 90.0% of this water level? Number t = 1.694 hr Incorrect.
