Age Distribution of the Population by Sex and Region (2011)
Elden [556K]

The consideration of the Age Distribution of the Population of the United States South Region shows that:

<h3>South Region:</h3>

Section: 1: Child Dependency Ratio: =31.4160%

Section: 2: Old-age Dependency Ratio: 18.9205%

Section: 3: Age Dependency Ratio: 50.3364%

Section: 4: Interpret: About 31% of the children and 19% of old people of the South region depend on their working adults.

Section: 5: Extend: This implies that more than 50% of children and old people in the United States depend on 50% of the working population for survival.

<h3>Data and Calculations:</h3>

Age                            Total   # Northeast   # Midwest   # South      # West

Both sexes             306,108      54,782         66,104      113,274        71,946

Under 15 years        62,155       10,034          13,180       23,671        15,269

15 to 64 years       204,775        37,101        44,209       75,347         48,117

65 years and older 39,178         7,647           8,715        14,256         8,560

<h3>South Region:</h3>

Section: 1: Child Dependency Ratio: =31.4160% (23,671/75,347 x 100)

Section: 2: Old-age Dependency Ratio: 18.9205% (14,256/75,347 x 100)

Section: 3: Age Dependency Ratio: 50.3364% (37,927/75,347 x 100)

Section: 4: Interpret: About 31% of the children and 19% of old people of the South region depend on their working adults.

Section: 5: Extend: This implies that more than 50% of children and old people depend on the working population.

Thus, the records show that a little over 50% of the population depends on less than 50% population for survival.

The men's world record for swimming 1500.0 m in a long course pool (as of 2007) is 14 min 34.56s. At this rate, how many seconds
Tcecarenko [31]
We must first find the rate taken to cover 1500.0 m within 14 min and 34.56 sec. We can first convert the time into seconds and hence, we have time = 14(60) + 34.56 = 874.56 seconds. Recall that rate = distance/ time. And using the given for the men's world record, we have rate = 1500.0 m / 874.56s = 1.715 m/s Now, to find the time taken to cover 0.350 miles, we can first convert the distance to meters then use the equation given below. time = distance/rate where distance is equal to 0.350(1609) = 563.15 m. Hence, we have time = 563.15 / 1.715 = 328.37 s From this, we can see that it will takes 328.37 seconds to cover 0.350 miles. <span>Answer: 328.37 seconds</span>
