Use the conversion tables or formulas on the inside back cover of the textbook for conversion equivalencies. In 2007 , the birth rate in the United States was estimated to be 14.3 births per 1000 persons. If the population estimate for the United States was 306 million, how many births were expected that year?

Short Answer

Expert verified
Answer: Approximately 4,375,800 births were expected in the United States in 2007.

Step by step solution

01

Understand the birth rate formula

Birth rate is calculated as the number of births per 1000 persons. In this problem, the birth rate is given as 14.3 births per 1000 persons.
02

Identify the given data

The population estimate for the United States in 2007 is given as 306 million people. The birth rate is given as 14.3 births per 1000 persons.
03

Convert the population estimate to thousands

Since we have the birth rate in terms of 1000 persons, to find the number of births, we need to convert the population estimate into thousands. 1 million = 1,000,000 Therefore, 306 million = 306 × 1,000,000 = 306,000,000 Now, we can convert this figure into thousands by dividing by 1000: 306,000,000 persons ÷ 1000 = 306,000 groups of 1000 persons.
04

Calculate the number of expected births

Now that we have the population in thousands and know the birth rate, we can calculate the number of expected births by multiplying the birth rate by the number of groups of 1000 persons: Expected births = Birth rate × Number of groups of 1000 persons Expected births = 14.3 births per 1000 persons × 306,000 groups of 1000 persons
05

Solve for the expected births

Now, we can solve for the number of expected births: Expected births = 14.3 × 306,000 = 4,375,800 Hence, there were approximately 4,375,800 births expected in the United States in 2007.

You wait for the price to drop on a diamond-studded watch at Macy's. Originally, it cost \(\$ 2500\). The first discount was \(20 \%\) and the second discount is \(50 \%\). a. What are the decay factors for each of the discounts? b. What is the effective decay factor for the two discounts? c. Use the effective decay factor in part b to determine how much you will pay for the watch.
Complete the following table by representing each ratio in all four formats.
