Big babies: The Centers for Disease Control and Prevention reports that 20% of baby boys 6 - 8 months old in the United States weigh more than 20 pounds. A sample of 17 babies is studied. Round the answers to at least three decimal places. Part 1 of 4 (a)What is the probability that exactly 8 of them weigh more than 20 pounds? The probability that exactly 8 of them weigh more than 20 pounds is .008 . Alternate Answer: The probability that exactly 8 of them weigh more than 20 pounds is 0.008 . Part 2 of 4 (b)What is the probability that more than 6 weigh more than 20 pounds? The probability that more than 6 weigh more than 20 pounds is .131 . Correct Answer: The probability that more than 6 weigh more than 20 pounds is 0.038 . Part: 2 / 4 2 of 4 Parts Complete Part 3 of 4 (c)What is the probability that fewer than 6 weigh more than 20 pounds? The probability that fewer than 6 weigh more than 20 pounds is

Write a script to find Nmin, the smallest possible value for N in Eq. (1) so that ln(5) evaluated using myLog with Matlab's default double precision arithmetic is exact when written as a half-precision binary floating point number in engineering notation. Use decimal2binary developed in Module 1 to answer this question and do not use Matlab's half(). Just setting Nmin without an algorithm to find its value will not give any credit.

Your task is to express the POLYVAL algorithm, which implements Horner's method for polynomial evaluation, in recursive form. Given a list (array) of n numbers representing the coefficients of polynomial p(x) as input, and a number a, return the value of p(a). 2a) Express your algorithm recursively. No for, while, etc. loops are allowed. Only recursive calls, if, if..else statements, arithmetic operations, and assignments may be used. 2b) Let the number of comparisons and basic operations (assignment, arithmetic operations, etc.) in your algorithm be f(n), where n is the degree of the polynomial p(x). Find a recurrence relation for f(n) and also state what f(1) equals to. 2c) Solve the recurrence you derived and find the asymptotic running time of our algorithm using both O() and Ω().

You are designing a gas turbine to be used in a new power station. Your design is shown in the schematic below. Determine the total entropy generation and the second law efficiency of the turbine. Treat the gas as air and assume that it behaves as an ideal gas. Do not assume constant specific heats. (1) Air (ideal gas) $T_1$ = 800K $P_1$ = 1MPa $\dot{m}$ = 20kg/s Turbine Power out $W_{turb}$ = ?? (0) Surroundings $T_0$ = 25°C $P_0$ = 1atm Heat out $Q_{turb}$ = 3MW (2) Air (ideal gas) $T_2$ = 340K $P_2$ = 200kPa

(a) In the quick return mechanism shown in Fig 1, the distance between the fixed centres CB = 90 mm, crank BA = 180 mm, CD = 180 mm, and the rod DE = 360 mm with its centre of mass, G, 90 mm from D. If AB rotates at 120 rpm clockwise, find graphically for the given position the linear velocity of G and the angular velocity of DE. If the rod DE has a mass of 7 kg, and radius of gyration about G is 120 mm, find its kinetic energy.
