QuestionIn 2015, North Dakota had 545,027 drivers and Wyoming had 422,450. Estimate total drivers by rounding to the nearest ten thousand. Is your estimate reasonable?

Studdy Solution

STEP 1

Assumptions1. The number of licensed drivers in North Dakota in2015 is545,027. . The number of licensed drivers in Wyoming in2015 is422,450.
3. We need to find the total number of licensed drivers in both states.
4. We need to round each number to the nearest ten thousand to estimate the total.

STEP 2

First, we need to round each number of licensed drivers to the nearest ten thousand. The number545,027 rounds down to540,000 and the number422,450 rounds up to420,000.
North Dakota rounded=540,000North\, Dakota\, rounded =540,000Wyoming rounded=420,000Wyoming\, rounded =420,000

STEP 3

Now, we add the rounded numbers together to get an estimate of the total number of licensed drivers in both states.
Total estimated drivers=North Dakota rounded+Wyoming roundedTotal\, estimated\, drivers = North\, Dakota\, rounded + Wyoming\, rounded

STEP 4

Plug in the rounded values for North Dakota and Wyoming to calculate the estimated total.
Total estimated drivers=540,000+420,000Total\, estimated\, drivers =540,000 +420,000

STEP 5

Calculate the estimated total number of licensed drivers.
Total estimated drivers=540,000+420,000=960,000Total\, estimated\, drivers =540,000 +420,000 =960,000

STEP 6

Now, we calculate the actual total number of licensed drivers in both states by adding the original numbers together.
Total actual drivers=Number of drivers in North Dakota+Number of drivers in WyomingTotal\, actual\, drivers = Number\, of\, drivers\, in\, North\, Dakota + Number\, of\, drivers\, in\, Wyoming

STEP 7

Plug in the actual values for North Dakota and Wyoming to calculate the actual total.
Total actual drivers=545,027+422,450Total\, actual\, drivers =545,027 +422,450

STEP 8

Calculate the actual total number of licensed drivers.
Total actual drivers=545,027+422,450=967,477Total\, actual\, drivers =545,027 +422,450 =967,477

STEP 9

To check if our estimate is reasonable, we compare the estimated total to the actual total. If they are close, then our estimate is reasonable.
The estimated total number of licensed drivers in both states in2015 is960,000 and the actual total is967,477. Since these two numbers are close, our estimate is reasonable.
