Mothers Against Drunk Driving is a very visible group whose main focus is to educate the public about the harm caused by drunk drivers. A study was recently done that emphasized the problem we all face with drinking and driving. Four hundred accidents that occurred on a Saturday night were analyzed. Two items that were noted included the number of vehicles involved and whether alcohol played a role in the accident. The numbers are shown below: Number of Vehicles Involved Did Alcohol Play a Role? | 1 | 2 | 3 | Totals Yes | 50 | 100 | 20 | 170 No | 25 | 175 | 30 | 230 Totals | 75 | 275 | 50 | 400 Referring to the data above, what is the probability of accidents that involved both no alcohol and 3 vehicles? 0.02 0.05 .0625 0.075

Studies show that texting while driving is as risky as driving with a 0.08 blood alcohol level, the standard for drunk driving. The bar graph shows the number of fatalitics in the United States involving distracted driving from 2004 through 2008 . Although the distracted category involves such activities as talking on cellphones, conversing with passengers, and eating, experts at the National Highway Traffic Safety Administration claim that texting while driving is the clearest menace because it requires looking away from the road. (GRAPH CAN'T COPY) Shown to the right of the bar graph is a scatter plot with a line passing through two of the data points. Use the two points whose coordinates are shown by the voice balloons to write the slope-intercept form of an equation that models the number of highway fatalities involving distracted driving, $y,$ in the United States $x$ years after 2004. b. In 2010 , surveys showed overwhelming public support to ban texting while driving, although at that time only 19 states and Washington, D.C., outlawed the practice. Without additional laws that penalize texting drivers, use the model from part (a) to project the number of fatalities in the United States in 2014 involving distracted driving.
