The table below shows the number of state-registered automatic weapons and the murder rate for several Northwestern states. x 11.4 8.3 6.9 3.9 2.3 2.5 2.6 0.8 y 13.4 11.4 10.1 7.4 5.9 6.3 6.3 4.5 x= thousands of automatic weapons y= murders per 100,000 residents This data can be modeled by the equation y=0.85x+4.05. Use this equation to answer the following; Special Note: I suggest you verify this equation by performing linear regression on your calculator. A) How many murders per 100,000 residents can be expected in a state with 7.8 thousand automatic weapons? Answer = Round to 3 decimal places. B) How many murders per 100,000 residents can be expected in a state with 1.4 thousand automatic weapons? Answer = Round to 3 decimal places.
Equations and Inequations
Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
