Answer :
Final answer:
To find the percent error in Nana's estimation of her dad's weight, we subtract the estimated weight from the actual weight and calculate the percent difference.
Explanation:
To find the percent error, we first need to calculate the absolute difference between Nana's estimation and the actual weight of her dad. The absolute difference is obtained by subtracting the estimated weight from the actual weight: 195 - 190 = 5 pounds. Next, we calculate the percent error using the formula: (Absolute difference / Actual value) × 100. Plugging in the values: (5 / 190) ×100 = 2.63%. Therefore, the percent error is 2.63% (Option B).
The percent error in Nana's estimate of her dad's weight is 2.63%. This is calculated using the formula for percent error: |Estimated Value - Actual Value| / |Actual Value| x 100%.
To find the percent error, you can use the following formula: |Estimated Value - Actual Value| / |Actual Value| x 100%. In this case, the estimated value is Nana's guess (195 pounds), and the actual value is the result from the scale (190 pounds). So:
|195 - 190| / |190| x 100% = 5 / 190 x 100% = 2.63%
So, the percent error in Nana's estimate of her dad's weight is 2.63%. Thus, the correct answer to your question is B) 2.63%.
