Scientists have developed a recursion formula to determine the number of insects in a given population for eachinterval, n, of time, . an = kan-1(1-an-1), where k is a constant called the Malthusian factor.a. Assuming n is measured in weeks, calculate the insect population for weeks 2, 3, and 4 if the initialpopulation is 112, and the Malthusian factor for this population is -9.5.

To compute a student's Grade Point Average (GPA) for a term, the student's grades for each course are weighted by the number of credits for the course. Suppose a student had these grades: 4.0 in a 5 credit Math course 2.5 in a 3 credit Music course 2.7 in a 5 credit Chemistry course 3.3 in a 6 credit Journalism course What is the student's GPA for that term? Round to two decimal places Student's GPA =
2. Determine the exact value of the 12th term in the expansion of Expectations 16 2 X The answer is presented as an equation with tn, and the full value of the term, where n is the corresponding term number. The answer is presented with exact values, which means decimals are not present (on a diploma exam, not using exact values could drop your score to a 0.5)
For numbers 24-26: Aquascaping involves growing aquatic plants and aesthetically arranging them in an aquarium like a natural landscape. Success of growing plants depends on several factors such as light condition, water pH, and carbon dioxide level. It is of interest to determine if varying concentrations of carbon dioxide (0.5 ppm, 1.2 ppm, 1.5 ppm) introduced to an aquarium will promote or deter an aquatic plants' growth. Ten aquariums with one-week old plant were set-up and randomly assigned to each treatment.
