Answer:
Percent error of Martha's estimation is 18.48%.
Step-by-step explanation:
The number of estimated marbles in a jar = 97
The number of actual marbles in a jar = 119
Now, ERROR = ACTUAL VALUE - ESTIMATED VALUE
= 119 - 97 = 22
So, the error in counting marbles = 22 marbles.
Now,
or, Percentage error = 18.48%
Hence, percent error of Martha's estimation is 18.48%.
The answer I’m pretty sure is 5 and if it’s not that it’s -5. It’s one of those let me know if it not and I’m sorry.
