An average computer mouse inspector can inspect 50 mice per hour. The 42 computer mice inspectors at a factory can only inspect 46 mice per hour with a standard deviation of 14. Does the company havea reason to believe that these inspectors ar slower than average?

How do you evaluate this? I was wondering what method you use to evaluate from :

(2/n) [(1+2i/n)^2 + 9]

to here:

(8i/n^2+ 8i^2/n^3 – 16/n)

Btw, this is an n Σ i=1 function.

The strength of a rectangular beam is proportional to its width times the square of its depth. Find the dimensions of the strongest rectangulare beam that can be cut from a 12 in. diameter log.



I assumed the strongest beam to be a square rectangle, with sides eqaul to the square root of 72...But I'm not sure how to solve for the depth at all, and i dont know if I need to equations to relate to determine the maximum of the function. Please Help.

if the problem is

x^-2y^-12/x^-6y^-2, would you have to simplify it first or switch it--- x^6y^2/x^2y^12

I have the total population for each state and then the number of deaths per 100,000 for each state should I divide the population by 100,000 then multiply that answer by the deaths per 100,000 to get an answer i.e if the population of Texas is 22,968,248 should i divide that by 100,000 and then multiply that answer by 237.8 (number of deaths per hundred thousand due to heart disease)?

The questions are:

A train leaves a city heading west and travels at 50 mph. Three hours later, a second train leaves from the same place and travels in the same direction at 65 mph. How long will it take for the second train to overtake the first train?


The second question:

A ship travels from New York to Southhampton, England at 33 mph. A plane traveling at 605 mph takes 104 hours less time to make the same trip. How far apart are the two cities?


I need to show all work.
