Solve the problem.The rates of death (in number of deaths per 100,000 population) for 1-4 year olds in the United States between 1980-1995 are given below. (Source: NCHS Data Warehouse) A logarithmic equation that models this data is y = 822.99 - 167.55 ln x where x represents the number of years since 1900. Use this equation to predict the rate of death for 1-4 year olds in 2005.

What will be an ideal response?


43.2 deaths per 100,000
