Consider the the distribution of under-inflated tires on a four-wheel automobile. The mass density is given by: p(0) = 0.4, p(1) = p(2) = p(3) = 0.1, p(4) = 0.3 a) Find the expected value and the variance of this distribution. b) For what proportion of
4. ## Chemistry

The dimerization of butadiene is a second order reaction process. In an experiment a sample of 0.0087 mol of butadiene was heated in a liter flask. After 600 seconds 21% of the butadiene has dimerized. Calculate the rate constant.
