Karen measures the width of a garden plot and records that it is 44.25 meters. its actual width is 45.5 meters. what is the percent error in the measurement, to the nearest tenth of a percent? 0.2% 0.3% 2.7% 3.2%

Answer

Find out the what is the percent error in the measurement, to the nearest tenth of a percent .  

To prove

Formula

Where error = | Approx - Exact |

As given

Karen measures the width of a garden plot and records that it is 44.25 meters. Its actual width is 45.5 meters.

Approx value = 44.25 meters    

Actual value = 45.5 meters        

error = | 44.25 - 45.5 |

         = |-1.25|

         = 1.25

Put in the formula

Percentage error = 2.7%

Therefore the percentage error is 2.7% .

a

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
