- On the Great Stark island, the likelihood of a residential fire is evenly distributed at 12 per month. Residents are evenly distributed along the 64-mile perimeter of the island. The government is providing fire protection, and a fire department's fixed cost is $60,000 per month. If the travel cost to fight a fire is $2,500 per mile, what is the optimal number of fire departments?To receive a C grade, a student must average more than 77 but less than or equal to 85. If Noah received a C in the course and had five grades of 73, 85, 73, 69, and 78 before taking the final exam, what were the possible grades for his final if there were 100 points possible? (Assume all six grades are weighted equally and let x represent the unknown score.)Q2 how many pPhones should the pear company produce and sell to maximize profit? What is the answer for x ? x=??

- For a population with μ =100 and σ = 20, what is the X value corresponding to z = -0.50?Miss Piggy, trying to prove that she is not just a pretty face, urged all of the Muppets to apply to law school at Sock Puppet University. In preparation for their law school applications, each Muppet took the LSAT and received scores uniformly distributed from Animal’s score of 10 to Kermit the Frog’s score of 180. The total cost (in present value) of attending Sock Puppet University Law School is $136,000. The Muppets’ earnings are directly related to their performance on the LSAT, regardless of whether they go to law school. Those who do not go to law school will earn a present value of YNL = 100×LSAT, while those who do attend law school earn YL =1,000+1,000×LSAT. What is the average earnings of the Muppets who attend law school and the earnings of the Muppets who do not attend law school?
