Question

Last year, Theodora estimated that she would sell 96 bracelets. But at the end of the year, she had 16 bracelets left over. Which explains how Theodora can find the percent error of her estimate? First, find that the exact value is 96 minus 16 = 80. The error is 16. The absolute error is 16. Set up the ratio with the absolute error: StartFraction 16 over 80 EndFraction. Divide and then multiply by 100 to find the percent error: (0.20) (100) = 20 percent. First, find that the exact value is 96 minus 16 = 80. The error is 16. The absolute error is 16. Set up the ratio with the absolute error: StartFraction 16 over 96 EndFraction. Divide and then multiply by 100 to find the percent error: (0.166) (100) = 16.7 percent. First, find that the exact value is 96 +16 = 112. The error is 16. The absolute error is 16. Set up the ratio with the absolute error: StartFraction 16 over 112 EndFraction. Divide and then multiply by 100 to find the percent error: (0.14286) (100) = 14.3 percent. First, find that the exact value is 96 + 16 = 112. The error is 16. The absolute error is 32. Set up the ratio with the absolute error: StartFraction 32 over 112 EndFraction. Divide and then multiply by 100 to find the percent error: (0.285) (100) = 28.5 percent.

Answer 1

Answer:

28.5%

Step-by-step explanation:

first, find that the exact value is 96 minus 16 = 80. The error is 16. The absolute error is 16. Set up the ratio with the absolute error: StartFraction 16 over 80 EndFraction. Divide and then multiply by 100 to find the percent error: (0.20) (100) = 20 percent. First, find that the exact value is 96 minus 16 = 80. The error is 16. The absolute error is 16. Set up the ratio with the absolute error: StartFraction 16 over 96 EndFraction. Divide and then multiply by 100 to find the percent error: (0.166) (100) = 16.7 percent. First, find that the exact value is 96 +16 = 112. The error is 16. The absolute error is 16. Set up the ratio with the absolute error: StartFraction 16 over 112 EndFraction. Divide and then multiply by 100 to find the percent error: (0.14286) (100) = 14.3 percent. First, find that the exact value is 96 + 16 = 112. The error is 16. The absolute error is 32. Set up the ratio with the absolute error: StartFraction 32 over 112 EndFraction. Divide and then multiply by 100 to find the percent error: (0.285) (100) = 28.5 percent.
