Suppose that, after measuring the duration of many telephone calls, a telephone company found their data was well-approximated b
y the density function p(x)=0.8????−0.8x, where x is the duration of a call, in minutes. (a) What percentage of calls last between 1 and 2 minutes? Percent = 100(-e^(-1.6) + e^(-0.8)) percent (b) What percentage of calls last 1 minutes or less? Percent = 100(1-e^(-0.8)) percent (c) What percentage of calls last 4 minutes or more? Percent = 100(e^(-3.2)) percent (d) What is the cumulative distribution function, P(????)?
The transformation preserves only angle measurement is dilation. The transformation helps in taking up the production of an image that is of the same shape as the main original image.
