Answer:
range: 13, mean: 6
Step-by-step explanation:
You get range by subtracting the largest number (15) by the smallest number (2). 15-2 equals 13.
You get mean by adding up all of the numbers (2+2+3+4+5+5+6+8+10+15=60) and dividing the sum by the amount of numbers in the list (10). 60/10 equals 6.
2
Because 20 has to be doubled to become 40. While 40 is twice as much as 20 so you just divide 40 by 20 to get 50%.
Explanation:
20 x 20 = 40 = 100%
40 / 20 = 50%
