Donelle measures the mass of 10 pennies and records her measurements in kilograms. She wants to determine the mean mass of her pennies.
What should Donelle do to make it easier to calculate the mean mass of her pennies?
Use a computer to perform the mean calculation.
Convert the units of her measured values to milligrams.
Convert the units of her measured values to grams.
Round her measured values to the nearest tenth.
is it the second one?
I be leave that it would be the third one as Grams are easier to use then Milligrams when you are working with pennys.
thank you
Yes, the second option, "Convert the units of her measured values to milligrams," would make it easier to calculate the mean mass of her pennies.
To calculate the mean mass, Donelle needs to add up all the measured values and then divide the sum by the total number of measurements. However, when the measurements are in kilograms, the resulting mean value might not be very convenient or easily understandable.
By converting the units of her measured values to milligrams, Donelle will have values that are easier to work with. Milligrams is a smaller unit of mass, and it will yield more manageable values when calculating the mean. Once she has the mean value in milligrams, she can always convert it back to kilograms if needed.
So, the correct answer is "Convert the units of her measured values to milligrams."
