#13 "Olympic Gold" The winning times for the 400m run at the Olympics have been decreasing over time for both men and women. In 1972, the winning men's time was 44.66 seconds and in 1996, the winning men's time was 43.39 seconds. a) Write an equation in slope-intercept form to predict the winning men's time, where x is the years since 1972. b) What does the dependent variable represent? c) What is the slope and what does it represent? Use the equation to predict the winning men's time in 2032. d) e) Use the equation to predict the year that winning men's time is 42.06 seconds. Math Byrd 2017 mk

Mercury poisoning is dangerous overload of mercury within the body. a major source of mercury within the body, a major source of mercury poisoning is consuming fish that contain mercury. certain fish are more prone to having higher levels of mercury than others. the pie chart shows the distribution of four breeds of fish at a hatchery. the hatchery has approximately 6,000 fish. a biologist from the centers for disease control and prevention randomly test 5% of each breed of fish for mercury content. her findings are shown in the following table. based on the biologist's findings, if a single salmon is randomly selected from those that were tested, what is the probability that this particular fish would have a dangerous mercury level? a) 0.001 b) 0.004 c) 0.02 d) 0.08
