Round it to nearest fifths​
Yanka [14]

Answer:

mean = $11.15

median = $11.30

mode = $9.90, $10.70, $11.90, $12.05

Step-by-step explanation:

Ordered from smallest to largest

9.89, 10.71, 11.90, 12.06

The mean is the middle number.

There are two numbers in the middle so you have to add them together and divide by 2.

(10.71 + 11.90)/2 = 11.305

rounded 11.30

Mode is the number that appears the most. All of the prices are listed once. They are all the mode.

Mean is (10.71+11.90+9.89+12.06)/4 = 11.14

round 11.15
