Joshua tells his friends that for there to be snow it has to be 32o F. He uses his thermometer outside and sees snow. He finds it is only is 34oF. What is his percent error? (Round to the nearest tenth)

Percentage error = -5.9%

Step-by-step explanation:

Step 1

Percentage error =Approximate Value − theoretical  Value / Theoretical value    ×  100%

or

Percentage error = Assumed number - Result number / Result number x 100

Given  Assumed number / Approximate Value=  32o F

Result number/ Theoretical value= 34o F.

Step 2---

Percentage error = (32 - 34)/ 34  x 100

= - 2/34 x 100

= - 5.88%

Joshua  was in error by - 5.88 % which when rounded to nearest tenth gives - 5.9%.
