Refer to exhibit 1 below. What is the prediction equation for determining Heat BTU’s? a. Heat BTU’s = 389 + 2.12 Burn Rate + 5.32 Fuel density + 24.1 Mixing Time b. Heat BTU’s = 66 + 1.21 Burn Rate + 0.96 Fuel density - 1.87 Mixing Time c. Heat BTU’s = 5.89 + 1.75 Burn Rate + 5.52 Fuel density - 12.92 Mixing Time d. Heat BTU’s = 389 + 2.12 Burn Rate + 5.32 Fuel density - 24.1 Mixing Time Impossible to determine from this research
A crayon manufacturer is comparing the effects of two kinds of yellow dye on the brittleness of crayons. Dye B is more expensive than dye A, but it is thought that it might produce a stronger crayon. Four crayons are tested with each kind of dye, and the impact strength (in joules) is measured for each. The results are as follows: Dye A: 1.0 2.0 1.2 3.0 Dye B: 3.0 3.2 2.6 3.4 a) Can you conclude that the mean strength of crayons made with dye B is greater than that of crayons made with dye A? b) Can you conclude that the mean strength of crayons made with dye B exceeds that of crayons made with dye A by more than 1 J?

Consider the population model dP/dt = 2P −P^250 for a species of fish in a lake. Suppose it isdecided that fishing will be allowed, but it is unclear how many fishing licenses should beissued. Suppose the average catch of a fisherman with a license is 3 fish per year (these arehard to catch fish). What is the largest number of licenses that can be issued if the fish areto have a chance to survive in the lake?
