Part E [20 pts] Since 2009, the number of analog theater screens has been on the decline in the U. S. The number of analog movie screens, y, each year can be estimated by the equation y = 7000x + 31800, where x is the number of years since 2009. So, that means 2009 represents 0 years, 2010 represents 1 year, and so on. 1) Find the x-intercept of this equation.

Suppose babies born after a gestation period of 32 to 35 weeks have a mean weight of 25002500 grams and a standard deviation of 800800 grams while babies born after a gestation period of 40 weeks have a mean weight of 27002700 grams and a standard deviation of 385385 grams. if a 3232-week gestation period baby weighs 21252125 grams and a 4040-week gestation period baby weighs 23252325 grams, find the corresponding z-scores. which baby weighs lessless relative to the gestation period?
