What is the midrange of

{6,7,8,9,10,12,15,15,20,28}

the formula for midrange is

M=(maxX-minX)/2 (i think)
so it'd be
M= (28-6)/2
M=(22)/2
M=11

Anne is correct.

To find the midrange of a set of numbers, follow these steps:

1. Start by arranging the numbers in ascending order: {6, 7, 8, 9, 10, 12, 15, 15, 20, 28}.

2. Next, find the lowest number (the minimum) and the highest number (the maximum) in the set. In this case, the minimum is 6 and the maximum is 28.

3. To calculate the midrange, simply average the minimum and maximum values. Add the minimum and the maximum together and divide the sum by 2: (6 + 28) / 2 = 34 / 2 = 17.

Therefore, the midrange of the set {6, 7, 8, 9, 10, 12, 15, 15, 20, 28} is 17.
