Answer:

mean=28.8

median=31

Step-by-step explanation:

mean=sum of all values/number of all values

mean=40+45+7+21+31+40+45+7+21+31/10

=288/10

mean=28.8

Median

arrrange in order

7,7,21,21,31,31,40,40,45,45

in case of even ungrouped data median is the average of middle two values

= (31+31)/2

In 2 seconds, an elevator travels 40 feet. In 3 seconds, the elevator travels 60 feet. In 4 seconds, the elevator travels 80 fee

professor190 [17]

Y=20x because if it travels 40 in 2 seconds that means in 1 second it traveled 20 so every second the elevator travels 20 so y is the total distance and X is the amount of seconds
