Answer:
Tim's percent error is 58.1 % .
Step-by-step explanation:
Formula
[tex]Percentage\ error = \frac{Change\ in\ value\times 100}{Original\ value}[/tex]
Where
Change in value = |Approx value - original value|
As given
Tim predicts he will get 98 points on the next exam.
If Tim actually earned 62 points .
Original value = 62
Approx value = 98
Change in value = |98 - 62|
= 36
Putting all the values in the formula
[tex]Percentage\ error = \frac{36\times 100}{62}[/tex]
[tex]Percentage\ error = \frac{3600}{62}[/tex]
Percentage error = 58.1 % (Approx)
Therefore Tim's percent error is 58.1 % .
