Answer: 33%
Step-by-step explanation: The math of percentages shows that as losses get larger, the return necessary to recover to break-even increases at a much faster rate. A loss of 10 percent necessitates an 11 percent gain to recover. Increase that loss to 25 percent and it takes a 33 percent gain to get back to break-even.
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%.
Answer:
2.38
Step-by-step explanation:
To find the standard deviation, subtract the mean from each number given, square each outcome, add them all together, divide all of that by the number of outcomes, then square root the whole equation.
Doing this gets you to 2.380476143, rounding this to two decimal places gives 2.38
