Question: A city has a crime rate of 5 incidents per 1000 people. If the population is 50,000, how many incidents are expected?

Options:

Correct Answer: 250

Solution:

Expected incidents = (5/1000) * 50000 = 250 incidents.

A city has a crime rate of 5 incidents per 1000 people. If the population is 50,000, how many incidents are expected?

A city has a crime rate of 5 incidents per 1000 people. If the population is 50,000, how many incidents are expected?

Step 1: Understand the crime rate. The crime rate is 5 incidents for every 1000 people.
Step 2: Identify the total population of the city, which is 50,000 people.
Step 3: Set up the calculation to find the expected number of incidents. You will use the formula: (crime rate / 1000) * population.
Step 4: Plug in the numbers into the formula: (5 / 1000) * 50000.
Step 5: Calculate the result. First, divide 5 by 1000 to get 0.005.
Step 6: Multiply 0.005 by 50000 to find the expected incidents: 0.005 * 50000 = 250.
Step 7: Conclude that the expected number of incidents is 250.
