explain Teresas percent error can be solved by using the formula:Percent Error = (Estimated Value - Actual Value) / Actual Value x 100%The estimated value is 18 feet, and the actual value is 16 feet.| (18 - 16) / 16 | * 100% = | 2 / 16 | * 100% = 0.125 * 100% = 12.5%Therefore, Teresa's percent error is 12.5%.
Teresa's percent error can be calculated by using the formula for percent error: (Estimated Value - Actual Value) / Actual Value x 100%.
In this case, the estimated value is given as 18 feet and the actual value is given as 16 feet. Plugging these values into the formula, we get:
Percent Error = (18 - 16) / 16 * 100%
Simplifying the expression within the parentheses, we have:
Percent Error = 2 / 16 * 100%
Simplifying the fraction, we get:
Percent Error = 0.125 * 100%
Finally, multiplying the decimal by 100% gives us:
Percent Error = 12.5%
Therefore, Teresa's percent error is 12.5%.
