Question
he table below shows the number of state-registered automatic weapons and the murder rate for several Northwestern states.
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 9 thousand automatic weapons?
Answer = Round to 3 decimal places.
B) How many murders per 100,000 residents can be expected in a state with 2.9 thousand automatic weapons?
Answer = Round to 3 decimal places.
| xx | 11.3 | 8.5 | 7.2 | 3.4 | 2.5 | 2.7 | 2.1 | 0.5 |
|---|---|---|---|---|---|---|---|---|
| yy | 13.7 | 11 | 10.2 | 7.2 | 5.9 | 6.5 | 5.6 | 4.7 |
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 9 thousand automatic weapons?
Answer = Round to 3 decimal places.
B) How many murders per 100,000 residents can be expected in a state with 2.9 thousand automatic weapons?
Answer = Round to 3 decimal places.
