Question

100%

The table below shows the number of state-registered automatic weapons and the murder rate for several Northwestern states.

xx	11.4	8	7	3.6	2.7	2.5	2.7	0.8
yy	13.4	11	10.1	7.2	6.2	6.1	6.4	4.7

xx = thousands of automatic weapons
yy = murders per 100,000 residents

This data can be modeled by the equation y=0.84x+4.09.y=0.84x+4.09. Use this equation to answer the following;

A) How many murders per 100,000 residents can be expected in a state with 4.7 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.
