The table below shows the number of state-registered automatic weapons and the murder rate for several Northwestern states.
x — 11.6 — 8.1 — 7.1 — 3.5 — 2.3 — 2.7 — 2.1 — 0.8
y — 13.9 — 11 — 9.8 — 7 —– 6.2 —- 6.4 — 5.8 — 4.5
x = thousands of automatic weapons
y = murders per 100,000 residents
This data can be modeled by the equation y = 0.85x + 4.02. Use this equation to answer the following;
A. How many murders per 100,000 residents can be expected in a state with 9.2 thousand automatic weapons? _________________ (round to 3 decimal places)
B. How many murders per 100,000 residents can be expected in a state with 1.5 thousand automatic weapons? _________________ (round to 3 decimal places).
