In Figure (a), you pull upward on a rope that is attached to a cylinder on a vertical rod. Because the cylinder fits tightly on the rod, the cylinder slides along the rod with considerable friction. Your force does work ( \( W=+100 \mathrm{~J}) \) on the cylinder-rod-Earth system (Figure (b)). An "energy statement" for the system is shown in Figure (c): the kinetic energy K increases by 50 J , and the gravitational potentia energy \( U_{g} \) increases by 20 J . (a) (b) (c) The only other change in energy within the system is for the thermal energy \( E_{t h} \). What is the change \( \Delta E_{t h} \) ? i

Which of the following best describes the hypothesis tested in the paper? Group of answer choices: Changing the sgRNA of the SpCas9-sgRNA complex increases the fidelity of the entire complex. The SpCas9-sgRNA complex specifically binds to the PAM sequence (protospacer adjacent motif). The SpCas9-sgRNA complex makes off-target edits. Disruption of one or more of the amino acid residues that contact DNA alters the energetics of the SpCas9-sgRNA complex so that it has diminished ability to cleave off-target sites.

Suppose we have a random sample from the following pdf: f(x;b)=(1)/(b)e^(-(x)/(b)) for x>0, b>0 and 0 < x < ∞. a. MLE of b is ar{x}. What is the MLE of (1)/(b)? b. What is the MLE of (1)/(b^(2))? c. Is the MLE you found in part (a) an UE of (1)/(b)? (Hint: Suppose Y=(2n(ar{x} ))/(b). We know that (:E((1)/(Y))=(1)/(2(n-1)) 3. Suppose we have a random sample from the following pdf: f(x;b)=e^(-x/b) for x>0, b>0 and 0 < x < ∞. a. MLE of b is X. What is the MLE of b. c. If not, obtain an UE using this MLE d.

McKnight Company is considering two different, mutually exclusive capital expenditure proposals. Project A will cost $400,000, has an expected useful life of 10 years and a salvage value of zero, and is expected to increase net annual cash flows by $70,000. Project B will cost $310,000, has an expected useful life of 10 years and a salvage value of zero, and is expected to increase net annual cash flows by $55,000. A discount rate of 9% is appropriate for both projects. Click here to view PV table. Compute the net present value and profitability index of each project. (If the net present value is negative, use either a negative sign preceding the number eg -45 or parentheses eg (45). Round present value answers to 0 decimal places, e.g. 125 and profitability index answers to 2 decimal places, e.g. 15.25. For calculation purposes, use 5 decimal places as displayed in the factor table provided.) Net present value - Project A Profitability index - Project A $ Net present value - Project B $ Profitability index - Project B Which project should be accepted based on Net Present Value? \text{\textbullet} should be accepted. Which project should be accepted based on profitability index? \text{\textbullet} should be accepted.
