The blood platelet counts of a group of women have a bell-shaped distribution with a mean of 257.8 and a standard deviation of 60.6. (all units are 1000 cells/mul.) using the empirical rule, find each approximate percentage below. a. what is the approximate percentage of women with platelet counts within 1 standard deviation of the mean, or between 197.2 and 318.4? b. what is the approximate percentage of women with platelet counts between 136.6 and 379.0?
the rocket cannot penetrate the ground, in a contextual sense, therefore the roots of this equation should be the domain of this function. i'll let you find the roots of this quadratic equation (hint: use the quadratic formula:
set the two equations for y equal to each other. solve for x. this will be the x-coordinate for the point of intersection. use this x-coordinate and plug it into either of the original equations for the lines and solve for y.
