Mark and Matthew signed up to walk in a 5K walk/run race. They predict it will take them 60 minutes to complete the race. Mark and Matthew finished the race in 53 minutes. What is the percent error? Round to the nearest tenth
To calculate the percent error, we need to find the difference between the predicted time and the actual time, and then divide it by the predicted time. Finally, we multiply by 100 to get the percentage.
1. Calculate the difference in time:
Actual time - Predicted time = 53 minutes - 60 minutes = -7 minutes
2. Calculate the absolute value of the difference:
| -7 minutes | = 7 minutes
3. Calculate the percent error:
Percent Error = (Absolute Value of the Difference / Predicted time) * 100
= (7 minutes / 60 minutes) * 100
= 0.1167 * 100
≈ 11.7
Therefore, the percent error is approximately 11.7%.
To find the percent error, we need to calculate the difference between the predicted time and the actual time, divided by the predicted time and multiplied by 100.
The predicted time is 60 minutes.
The actual time is 53 minutes.
The difference between the predicted and actual time is 60 - 53 = 7 minutes.
Now, we can calculate the percent error:
Percent Error = (|Predicted Time - Actual Time| / Predicted Time) * 100
Percent Error = (|60 - 53| / 60) * 100
Percent Error = (7 / 60) * 100
Percent Error = 11.67
Rounded to the nearest tenth, the percent error is 11.7%.
To find the percent error, we need to compare the predicted time with the actual time using the formula:
Percent Error = [(Actual Value - Predicted Value)/Predicted Value] * 100
In this case, the predicted time is 60 minutes, and the actual time is 53 minutes. Plugging these values into the formula:
Percent Error = [(53 - 60)/60] * 100
Simplifying the equation:
Percent Error = [-7/60] * 100
Calculating the value:
Percent Error = -11.7
Since we need to round to the nearest tenth, the percent error is approximately -11.7%.
Use the conversion ratio 1 liter equals 1,000 milliliters. A cylinder holds 6,750 milliliters. How many liters does it hold?(1 point)

To convert milliliters to liters, divide the number of milliliters by 1,000.
In this case, the cylinder holds 6,750 milliliters.
6,750 milliliters ÷ 1,000 = 6.75 liters
Therefore, the cylinder holds 6.75 liters.
Use the ratio 1 gallon equals about 3,785 milliliters. A container holds 34,065 milliliters. How many gallons does the container hold
To convert milliliters to gallons, divide the number of milliliters by 3,785.
In this case, the container holds 34,065 milliliters.
34,065 milliliters ÷ 3,785 = 9 gallons
Therefore, the container holds 9 gallons.
