An analysis of the final test scores for Managerial Decision Making Tools reveals the scores follow the normal probability distribution. The mean of the distribution is 75 and the standard deviation is 8. The instructor wants to award an "A" to students whose score is in the highest 10 percent. What is the dividing point for those students who earn an "A"? Top 10% is equivalent to the 90th percentile. Using our [URL='http://www.mathcelebrity.com/percentile_normal.php?mean=+75&stdev=8&p=+90&pl=Calculate+Percentile']percentile calculator[/URL], the 90th percentile cutoff point is [B]85.256[/B]

Demand curve of a software development firm digisign is qd= -16p^2 -4p + 250 .Carry out analysis of demand function and find out elasticity of demand Ed At p=25. Draw pertinent conclusions . qd(25) = -16*(25^2) - 4(25) + 250 qd(25) = -10000 - 100 + 250 qd(25) = -9850 So p = 25 and q = -9850 Ed = dp/dq Ed = -13p -4 Elasticity of Demand is found at: Ed = p/q * dp/dq Ed = 25/-9850 * (-13(25) - 4) Ed = 25/-9850 * -329 Ed = [B]0.835[/B]
