A student in a noon calculus class is watching two bugs near the center of a wall. One is an ant and the other is a beetle. At noon, the ant is 180 cm directly to the left of the beetle. The ant is crawling right at 30 cm/h and the beetle is crawling up at 45 cm/h. How fast is the distance between the bugs changing at 2:00 PM? Answer with an exact value. cm/h?

Near the equator, the Sun is approximately straight overhead at noon, and around 1000 W/m2 solar irradiance reaches Earth. Around this time of day, assuming ambient temperature of 40C, and a 10m x 10m x 2m-tall greenhouse with ¼”-thick glass walls that reflect away 20% of the incoming sunlight, and only thinking of conductive losses, estimate the maximum temperature reached in the interior of the greenhouse. Hint: when are losses and sources balanced? glass conductivity is 1.05 W/(m k)

A student desires to know if two-bedroom apartments for rent near the BRCC campus in Baton Rouge are significantly different, on average, than one-bedroom apartments for rent near the BRCC campus in Baton Rouge. The student collects data for a random sample of ten (10) advertisements for each of one-bedroom and two-bedroom apartments for rent near the BRCC campus in Baton Rouge. The data below shows the advertised rents (in dollars per month) for the selected apartments. 1 Bedroom 550...

There are two routes to get from the student dorms to class - a long route, which is scenic, and a short route, which is not scenic. You want to study whether the route that the students choose to take is independent of the weather (in the context of the table, this will mean whether X and Y are independent), and you generate the accompanying table of probabilities. Rainy (Y=0) Sunny (Y =1) Total Long (X=0) 0.1 0.3 0.4 Short...

There are three ways a student can end up in Calculus II at Augusta University. They can either take Calculus I or place into the class via AP credit. Further, some students take Calculus I the semester immediately before Calculus II but some students wait one or more semesters between taking Calc I and Calc II. A professor has a Calculus II class with 21 students, and they look at students’ final grades and how they got into the class....

Use the following population data for the next question(s). At a bird watching center, the number of yellow throated warblers observed over Memorial Day Weekend was: three on Saturday, 10 on Sunday, and eight on Monday. Assume sample sizes of two are randomly selected with replacement from this population. 10) List the nine different possible samples of yellow throated warblers and find the mean of each of them. 11) Identify the probability of each sample of yellow throated warblers and...
