Abiologist took a count of the number of fish in a particular lake and recounted the lake’s population of fish each of the next six weeks.
week 0 1 2 3 4 5 6
population 350 353 382 437 518 625 758 find a quadratic function that models the data as a function of x, the number of weeks. use the model to estimate the number of fish at the lake on week 8. (1 point) •p(x) = 13x2 – 10x + 350; 917 fish
•p(x) = 13x2 – 10x + 350; 1,102 fish
•p(x) = 18x2 + 10x + 300; 1,252 fish
•p(x) = 18x2 + 10x + 300; 1,532 fish

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.
