Answer:
15, 8, 13, 13
Step-by-step explanation:
(1) mean = Σx / n = 135 / 9 = 15
(2) range = highest value - lowest value = 21 - 13 = 8
(3) mode = 13 (most repeated value in data set)
(4) for 9 values in a data set, we have that (9 + 1) / 2 = 5th number
median = 13
60.75%. Set up a proportion equation with 243 over 400 and x over 100. Then, cross multiply and devide.
Answer:
Step-by-step explanation:
First you would plot the points- (0,2), (1,4), (2,6), (3,8)
Then if the points make a straight line when you connect them then it makes it a linear equation
To know if it is proportional or not you take the y points and put them over their x points, and if all of them end up with the same number than it is proportional
2/0=0, 4/1=4, 6/2=3, 8/3=8/3, therefore it is not proportional
