well to be honest i don't know
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, ![\textrm{ERROR PERCENTAGE} = \frac{\textrm{Error Value}}{\textrm{Actual Value}} \times 100](https://tex.z-dn.net/?f=%5Ctextrm%7BERROR%20PERCENTAGE%7D%20%3D%20%5Cfrac%7B%5Ctextrm%7BError%20Value%7D%7D%7B%5Ctextrm%7BActual%20Value%7D%7D%20%5Ctimes%20100)
![= \frac{22}{119} \times 100 = 18.48](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B22%7D%7B119%7D%20%5Ctimes%20100%20%3D%2018.48)
or, Percentage error = 18.48%
Hence, percent error of Martha's estimation is 18.48%.
Five percent of 5 is 100 because move the decimal two places to the left .05 and 5 divided by .05 is 100
You divide 18.40 by 2.3 to find out how many dollars per hour. 18.40/2.3=8.

Number of students N, y years
N = 700 + 50y
N = 700 + 50 x 10 = 1200 (C)
Left not painted percentage = 100 - 60 = 40 %
Left = 40/100 x 45 = 18 (H)
