Jim tree pays for shipping on the basis of weight. he knows weight is normally distributed so he can use the standard normal distribution. he decides to weigh 1,000 randomly trees in his shipment. next, he calculates the mean and standard deviation of their weights. he finds the mean is 30 lbs and the standard deviation is 10 lbs. now, jim uses the normal distribution table to calculate the number of trees in each segment of the distribution. standard deviation % from table no. of trees out of 1,000 0 to +1 (30 to 40 lbs) 34% +1 to +2 (40 to 50 lbs) 13.7% 137 +2 to +3 (50 to 60 lbs) 2.3% totals 50% 500

Problem PageA manufacturer produces two models of toy airplanes. It takes the manufacturer 32minutes to assemble model A and 8minutes to package it. It takes the manufacturer 20minutes to assemble model B and 10minutes to package it. In a given week, the total available time for assembling is 3200minutes, and the total available time for packaging is 960minutes. Model A earns a profit of $10 for each unit sold and model B earns a profit of $8 for each unit sold. Assuming the manufacturer is able to sell as many models as it makes, how many units of each model should be produced to maximize the profit for the given week? Note that the ALEKS graphing calculator can be used to make computations easier. ModelA:unit(s)ModelB:unit(s)
