7. As we did in lab, a scientist collects data on decaying radioactive barium. The initial count (activity) is 2488 and after 10 mins the count (activity) drops to 166. Using this data, what is the half-life of radioactive barium? Hint: use the data to find the decay constant (in lab we used a curve fit on the graph, but here use a formula) and then find the half-life

A sample of nine IT engineers was selected randomly from each of three regions in the United States (Northeast, Southeast, and West). The goal is to test if mean annual salaries for IT engineers are different among the three regions. The degrees of freedom for the error is Select one: a. 24 b. 23 c. 21 d. 3 The degrees of freedom for the treatment is Select one: a. 7 b. 3 c. 2 d. 8 What is the alternative hypothesis of interest? Select one: a. Average annual salaries in all the three regions are the same b. Average annual salaries of at least two regions are not the same What is the factor? Select one: a. Mean salaries b.

Could you please show the construction of the machines? I'm struggling following the word explanations. Finite State Machines The following two DFAs, G1 and G2, represent behaviors of a certain discrete-event system. In this question, you are expected to show steps of your construction method for the following parts of the question. You may use software (i.e., JFLAP) to help you with your construction but a single screenshot of the result, without any explanation or construction steps, will not be accepted. G1 Σ1={a,b} (a) Construct the composite machine G=G1×G2 (b) Construct the composite machine G = G1 || G2 (c) In this question you are required to develop a machine that accepts/marks the language characterized by L(G1)∪L(G2) (i.e., machine that accepts the union of the two languages). (d) In this question you are required to develop a machine that accepts/marks the language characterized by L(G1)∩L(G2) (i.e., machine that accepts the intersection of the two languages). Question 2: Finite State Machines (30 points) The following two DFAs, G1 and G2, represent behaviors of a certain discrete-event system. In this question, you are expected to show steps of your construction method for the following parts of the question. You may use software (i.e., JFLAP) to help you with your construction but a single screenshot of the result, without any explanation or construction steps, will not be accepted. G1 G2 Σ1={a,b} Σ2={b,c} (a) Construct the composite machine G=G1 ∪ G2 (b) Construct the composite machine G=G1|G2 (c) In this question you are required to develop a machine that accepts/marks the language characterized by L(G1)∪L(G2) (i.e., machine that accepts the union of the two languages). (d) In this question you are required to develop a machine that accepts/marks the language characterized by L(G1)∩L(G2) (i.e., machine that accepts the intersection of the two languages).
