The table below shows the number of state-registered automatic weapons and the murder rate for several Northwestern states.
xx11.68.46.73.52.72.62.30.7yy1410.99.976.26.35.74.3
xx = thousands of automatic weaponsyy = murders per 100,000 residents
This data can be modeled by the equation y=0.87x+3.83.y=0.87x+3.83. Use this equation to answer the following;A) How many murders per 100,000 residents can be expected in a state with 8.6 thousand automatic weapons?Answer = Round to 3 decimal places.B) How many murders per 100,000 residents can be expected in a state with 6.6 thousand automatic weapons?Answer = Round to 3 decimal places.
