Use the Income Statement above. Assume that the retention ratio is 50%, New Equity Raised is 20 and New Net Borrowing is -40.  What is the cash flow from assets?

Technetium-99m is widely used in medical imaging because it emits gamma rays but has a short half-life. Explain why having a short half-life is an advantage in medicine. Why are gamma rays particularly useful for diagnostic imaging compared to alpha or beta radiation?  

Five percent of widgets are defective.  An inspector randomly samples 12 widgets from a box. What is the probability of finding at least 2 defective widgets? (When you finish, make sure to show your work to the camera for few seconds, submit your work after you finish the exam.)

Using the Venn diagram of question 9, what is the value of Y

An unfair coin with​ Pr[H] =0.3 is flipped. If the flip results in a​ head, a marble is selected at random from a urn containing fourred and six blue marbles.​ Otherwise, a marble is selected from a different urn containing six red and two blue marbles. If the selected marble selected is​ red, what is the probability that the flip resulted in a​ head? (When you finish, make sure to show your work to the camera for few seconds, submit your work after you finish the exam. Make sure to show the filled tree Diagram)

Street Signs are shops all rely on neon lights to catch attention. Different gases in discharge tubes used for the lights emit different colors when an electric current passes through them. a) Explain, in terms of electronic structure, why each gas produces its own unique emission spectrum. (4 points) b) A neon sign emits bright red-orange light with a dominant wavelength of ~ 640 nm. Calculate the energy (in joules) of a single photon of this light. ( 4 points) Use h=6.626×10−34 J⋅sh = 6.626 \times 10^{-34} \, J \cdot s        c=3.00×108 m/sc = 3.00 \times 10^{8} \, m/s *make sure to show all your work – giving only the answer or irrelevant work will earn a zero grade.
