Will marked BRAINLIEST!! Kristin bought 9 potatoes at the farmer's market. The shortest diameter of each, in centimeter, is shown below.
3,3,4,4,5,6,7,8,9
After Kristin used one potato to make dinner, the median diameter of the remaining potatoes was 4.5 centimeters. Which of these could be the diameter, in centimeter, of the potatoes Kristin used? Plz explain and show work.

A. 3
B. 4
C. 5
D. 6

Respuesta :

The median is the number in the middle when they are arranged in order. If the median is 4.5, there will be an even amount of numbers and the middle will be in between 4 and 5. This means that one of the numbers 6-9 needs to be taken out. The only answer choice that meets this is D. 6

If you rewrite the numbers without the 6 you'll get 3, 3, 4, 4, 5, 7, 8, 9 and the median is 4.5.
