Scientists are studying a bacteria sample. The function
f(x)=245(1.12)* gives the number of bacteria in the sample at
the end of x days.
Which statement is the best interpretation of one of the values in
this function?
• The initial number of bacteria is 12.
The number of bacteria at the end of one day is 245.
The initial number of bacteria decreases at a rate of
88% each day.
The number of bacteria increases at a rate of 12% each
day.

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.
