Answer: 129
Step-by-step explanation:
the mean is the average of the data. including x, there are 6 data points
average = total/6
average = (98 + 123 + 105 +114 +109 + x) / 6
113 = (98 + 123 + 105 +114 +109 + x) / 6
113 = (549+ x) / 6
678 = 549 + x
x = 129
Answer:
6, 5, 1, 7, 9, 2, 4, 8, 3.
(from top to bottom, this should be right)
6 2/3 = 20/3 = 60/9
4 4/9 = 40/9
60/9 - 40/9 = 20/9 = 2 2/9
Answer: D, 110 !!!
y = (7 - x) / 2
You isolate the y by subtracting the x
2y = 7 - x
and then you divide by two to get the answer to y
(7 - x) / 2
