A) How many murders per 100,000 residents can be expected in a state with 4.4 thousand automatic weapons? Answer = Round to 3 decimal places. B) How many murders per 100,000 residents can be expected in a state with 9.5 thousand automatic weapons? Answer = Round to 3 decimal places.
Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
![The table below shows the number of state-registered automatic weapons and the murder rate for several Northwestern states.
| \( x \) | 11.4 | 8 | 6.9 | 3.9 | 2.9 | 2.5 | 2.6 | 0.6 |
|-----------|------|---|-----|-----|-----|-----|-----|-----|
| \( y \) | 13.5 | 10.5 | 9.9 | 7.6 | 6.7 | 6.5 | 6 | 4.2 |
\( x = \) thousands of automatic weapons
\( y = \) murders per 100,000 residents
This data can be modeled by the equation \( y = 0.83x + 4.09 \). Use this equation to answer the following:
Special Note: I suggest you verify this equation by performing linear regression on your calculator. Use the equation with the values rounded to two decimal places to make your predictions.
A) How many murders per 100,000 residents can be expected in a state with 4.4 thousand automatic weapons?
- Answer = [________] Round to 3 decimal places.
B) How many murders per 100,000 residents can be expected in a state with 9.5 thousand automatic weapons?
- Answer = [________] Round to 3 decimal places.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F05d3adb9-7fe4-4d5a-99c8-26255e44b92b%2F0e6df27f-6fed-47f4-bc11-91ae478258da%2Fd0hde0j_processed.jpeg&w=3840&q=75)
