I need assistance on q. 1 & 2. Question 1 0/2 pts 96 Details Score on last try: 0 of 2 pts. See Details for more. You can retry this question below. The physical fitness of an athlete is often measured by how much oxygen the athlete takes in (which is recorded in milliliters per kilogram, ml/kg). The mean maximum oxygen uptake for elite athletes has been found to be 65 with a standard deviation of 8.5. Assume that the distribution is approximately normal. Round your answers to 4 decimal places. Hint: Find the probability a normal random variable is in the right tail or the left tail. Find the probability that an elite athlete has a maximum oxygen uptake of at least 89.7 ml/kg. 0.002 Find the probability that an elite athlete has a maximum oxygen uptake of at most 56.5 ml/kg. 0.1525 Question Help: Message instructor Post to forum Submit Question Question 2 0/1pt 100 Details For a continuous random variable X that is normally distributed with mean = 58.4, and standard deviation = 10.4, find P29, the percentile value that divides the area under the density curve into 0.29 to the left and 0.71 to the right.

Problem 2 A plane truss is shown: 3 ft y RAY Link 2 Node #3 Link 7 RAX Node #1 Link 1 Node #2 300 Lbf Link 4 Link 5 Link 6 RBY Link 8 Link 9 Node #6 X Node #4 Node #5 800 Lbf 4 ft 4 ft 4 ft Equilibrium requires that the x- and y-components of the forces at the nodes sum to zero. Sum these forces to develop a system of equations $AF = b$, where $F$ is the member- and reaction-force vector defined as F = [F1 F2 F3 F4 F5 F6 F7 F8 F9 RAX RAY RBY]$^T$. where F1-F8 are the internal forces in links 1-8 respectively and where RAX, RAY, and RBy are the reaction forces applied by the supports as shown in the figure. (a) Print the resulting matrix A to at least two significant figures. (b) Print the resulting right-hand vector b to at least two significant figures.

Problem #3: Consider the $^{35}Cl_2$ molecule where $m_{Cl} = 34.97$ amu. The two chlorine atoms can vibrate relative to their common center of mass and also rotate about the center of mass. At equilibrium, the two atoms are separated by a distance of 0.1987 nm. (1 amu = $1.661 \times 10^{-27}$ kg) (a) Calculate the reduced mass and moment of inertia for this molecule. [6 pts] (b) Considering only rotational motion and ignoring vibrations, calculate the energies of the ground state ($J = 0$) and the first two excited states.
