Answer:

The percent error of Jocelyn's estimate is 2.14 .

Explanation:

Formula


Percentage\ error = (Error* 100)/(exact\ value)

Where


error = \left | approx\ value - exact\ value \right |

As given

Jocelyn estimates that a price of wood measures 5.5 cm.

If it actually measures 5.62 cm.

approx value = 5.5 cm

exact value = 5.62 cm

Put in the error formula


error = \left | 5.5 - 5.62 \right |


error = \left | -0.12\right |

error = 0.12

Put in the formula


Percentage\ error = (0.12* 100)/(5.62)


Percentage\ error = (12)/(5.62)

Percentage error = 2.14 (Approx)

Therefore the percent error of Jocelyn's estimate is 2.14 .
