Respuesta :
The range is calculated by subtracting the smallest number from the highest number of a sequence:
65 - 15 = 50
The midrange is calculated by adding the smallest and the highest number of a sequence and than dividing the result by 2:
65 + 15 = 80
80 / 2 = 40
The range is 50 and the midrange is 40 (c).
Hope it helped,
Happy homework/ study/ exam!
