Which table represents a proportional relationship that has a constant of proportionality equal to 0.8? A 2-column table with 4 rows. Column 1 is labeled x with entries 0, 4, 8, 10. Column 2 is labeled y with entries 0, 0.5, 1, 1.25. A 2-column table with 4 rows. Column 1 is labeled x with entries 0, 5, 10, 12.5. Column 2 is labeled y with entries 0, 4, 8, 10. A 2-column table with 4 rows. Column 1 is labeled x with entries 0, 4, 8, 10. Column 2 is labeled y with entries 0.8, 0.8, 0.8, 0.8. A 2-column table with 4 rows. Column 1 is labeled x with entries 0, 5, 10, 12.5. Column 2 is labeled y with entries 0.8, 10.8, 20.8, 25.8.

Let us imagine that the number of automobile accidents in a certain region are related to the regional number of registered automobiles in tens of thousands (b1), alcoholic beverage sales in $10,000 (b2), and decrease in the price of gasoline in cents (b3). furthermore, imagine that the regression formula has been calculated as: y = a + b1x1 + b2x2 + b3x3 where y = the number of automobile accidents, a = 7.5, b1 = 3.5, b2 = 4.5, and b3 = 2.5 calculate the expected number of automobile accidents for a football weekend if the region has 25,000 registered vehicles, $75,000 worth of beer is sold, and a gas war causes a 10 cent drop in a gallon of gas.
