Reactions such as the first step in glycolysis while otherwise improbable can nonetheless, proceed to completion because ? the reaction becomes probable due to gradient changes between substrate and product according to the Le Chatlier principle ? I do not know ? it can be coupled to an energy yielding reaction such as the hydrolysis of ATP ? the enzyme hexokinase simply changes the rate of the reaction thereby making an improbable reaction become probable ? it is impossible for an improbable reaction to proceed to completion in all of metabolism

The following data relate to sales figures of the bar in Sheraton hotel in Maui, Hawaii to the number of guests registered for last eight days. The operations manager of Sheraton is trying to build a regression model to help predict bar sales on the basis of number of guests. Days Bar sales (in $ thousands) Number of Guests 1 2 3 4 5 6 7 8 9 10 14 10 12 12 13 15 156 169 194 181 188 196 208 229 a) Using the given data, the least-squares regression equation for predicting the bar sales is (round your responses to two decimal places): $\hat{y} = \Box + \Box x$ where $\hat{y}$ = Estimated Dependent Variable and x = Independent Variable. b) The coefficient of correlation for the least-squares regression model = $\Box$ (round your response to two decimal places). For the least-squares model, the standard error of the estimate = $\Box$ (round your response to two decimal places).

Problem 10 [3 points for Correctness] Assume that you have a function called `is_prime` which consumes a positive number and returns `True` if the number is prime and `False` if the number is not prime. Your task is to use the Design Recipe to write a `main` function, that consumes no parameters, which prompts the user for a positive integer, $n$, and prints the first $n$ primes to the console. You do not need to write the `is_prime` function - it is already pre-defined. Include a docstring! Note: You do not need to provide `assertEqual` statements for this function. If the user input 3, your program should display: 2 3 5

15.6 Find the external torque ($\tau_{12}$) that must be applied to link 2 of the mechanism illustrated in Figure P15.6 to drive it at $\omega_2 = 1,800$ rad/s CCW and $\alpha_2 = 0$ rad/s$^2$. Link 2 is in a horizontal position, and it is balanced so that its center of mass is at the pivot $O_2$. The mechanism moves in the horizontal plane, and friction may be neglected. $W_3 = 0.708$ lb, $I_3 = 0.0194$ lb-$in^2$, $W_4 = 0.768$ lbs, $I_4 = 0.0112$ lb-$in^2$ $A^*A = 3.0 in$, $AB = 8.0 in$, $S^*D = 6.0 in$, $A^*D^* = 7.0 in$, $AG_2 = 4.0 in$, $r_{PA} = 3.0 in$

a) Create a NEW function: Isimp = Simpson (a, b, n) that outputs the integral of Fun (x) over [a,b] using n nodes with the Simpsons combined -1/3 and -3/8 rules. Make your life easier by assuming the number of nodes n will always be even. b) In addition to calling the Midpoint and Trapezoid functions, have your HW10_4 script call the new Simpson function to evaluate F. Change your script so that the number of nodes over which you run these three functions is now: n = [2 8 50 500 5000 50000]. (I made them all even now, to be consistent with your assumption for the Simpson method.) c) Uses the exact value F(70) = 1 - e^(-0.01)(70) to calculate the percent (relative) error in the approximations of F from ALL three of your own methods (midpoint, trapezoid, Simpsons) for all the nodes n above. d) Plots the absolute value of the % error for all three methods as a function of interval size, h. Please make each line different, so the midpoint method shows circles connected by black lines, the Trapezoid method shows triangles connected by green lines, and the Simpson's method shows squares connected by blue lines. Be sure to use the loglog plotting command to allow details to be seen even when the error gets very small. So, use something like this plot command: loglog (h, PctErrMid, 'ok-', h, PctErrTrap, '^g--', h, PctErrSimp, 'sb-.') Save this plot in pdf form as HW10_4.pdf e) Uses the built-in function integral to solve for F(70) directly (using your Fun.m for f(x)).
