The same athlete as above competes in their marathon and does okay. However, they want to continue to improve, and so they increase their exercise intensity to account for any improvements in VO2max, and continues to train for the next 2.5 years (increasing intensity as necessary, alternating intensity and duration training, and appropriately de-loading when necessary). Their Maximal aerobic capacity continues to improve. What physiologic components of our Fick Equation are primarily responsible for this improvement in maximal aerobic capacity (over this second, longer period of time), and what physiologic adaptations has led to these changes? The individual also begins incorporating resistance training into their training. What adaptations would they have in the first 6-10 weeks of this training As they continue (they’re continuing to train for 2.5 years), what other adaptations would they have to the resistance training. What are the Primary and Secondary cellular signals within the individual's skeletal muscles induced by resistance exercise, and what physiologic adaptations do each of these signals lead to? What, if any, interactions will this individual have between their aerobic and resistance training adaptations, AND why?

Texts: Let the random variable X be distributed as Binomial Bin(100,0.55). μX and σX are the mean and standard deviation of X respectively. You may use R for some of the calculations, but please also write out the relevant formulas. (a) Calculate P[μX − σX ≤ X ≤ μX + σX]. (b) Calculate P[μX − σX ≤ X ≤ μX + σX] using the normal approximation for the binomial. (c) Calculate P[μX − σX ≤ X ≤ μX + σX] using the Chebyshev inequality. (d) If X happens to be distributed as Binomial Bin(100,0.05) instead, would the normal approximation be appropriate or perhaps some other approximation?

Heritage Furniture Co. uses a standard cost system. One of the company's most popular products is an oak entertainment center that looks like an old icebox but houses a television, stereo, or other electronic components. The per-unit standard costs of the entertainment center, assuming a "nor- mal" volume of 1,000 units per month, are as follows. Direct materials, 100 board-feet of wood at $1.30 per foot Direct labor, 5 hours at $8.00 per hour Manufacturing overhead (applied at $22 per unit) Fixed ($15,000+ 1,000 units of normal production) Variable Total standard unit cost $130.00 40.00 $15.00 7.00 22.00 $192.00 During July, 800 entertainment centers were scheduled and produced at the following actual unit costs. Direct materials, 110 feet at $1.20 per foot Direct labor, 5\frac{1}{2} hours at $7.80 per hour Manufacturing overhead, $18,480 ÷ 800 units Total actual unit cost $132.00 42.90 23.10 $198.00 Prepare journal entries to assign manufacturing costs to the work in process inventory account and to record cost variances for July. Use separate entire for (1) direct materials, (2) direct labor, and (3) overhead costs.

A flat-plate airfoil is mounted in the test section of a supersonic wind tunnel. The angle of attack of the airfoil is set at 10 degrees and the static pressure on top of the airfoil, say station 2, is measured and found to be 1 atm. The nozzle throat area is 0.05 m$^2$ and the nozzle exit area is 0.0844 m$^2$. Calculate the reservoir pressure of the tunnel. First draw a careful sketch of the entire flow field, including the nozzle and identify key stations. Remember that the exit of the nozzle is the beginning of the test section, say Station 1. Hint: Do you work in the following order: A1/A$^*$, M1, P-M angle 1, P-M angle 2, M2, $p_{o2}/p_2$, $p_{o2}$, $p_o$
