![P(X1200)=1-P(X\leq 1200)\\=1-\int\limits^{1200}_{0} {\lambda e^{-\lambda x}} \, dx \\=1-\lambda[\frac{e^{-\lambda x}}{-\lambda} ]^{1200}_{0}\\=1-[1-e^{-\frac{x}{1000} }]^{1200}_{0}\\=1-[1-e^{-\frac{1200}{1000}}]\\=e^{-1.2}\\=0.3012](/tpl/images/0506/6269/7ba3b.png)

Jessica and martha each have a bag of cookies with unequal quantities. they have 30 cookies total between the two of them. each of them ate 6 cookies from their bag. the product of the number of cookies left in each bag is not more than 80. how many more cookies will jessica have martha? if x represents the number of cookies jessica started with, complete the statements below. the inequality that describes the relationship between the number of cookies each one of them has is x^2 - x +224 > = 0.jessica has at least cookies more than martha.
