The median is a halfway point in the set of data.

List the numbers in order from smallest to largest:

111, 129, 144, 149, 152, 162, 166, 171

Because there are an even number of values in the data set, find the two middle numbers, add them together and then divide by 2:

Median = ( 149 + 152 ) /2

Median = 150.5

The total rainfall in forks , washington, october was 8 3/8 in. in september ,60% less rainfall fell in October
iren2701 [21]
Rainfall in October in Forks, Washington = 8 3/8 inches
                                                                 = 67/8 inches
Percentage of rainfall that has fallen less in September in Forks, Washington = 60%
Let us assume the amount of rainfall in September in Forks, Washington = x
Then
100x/60 = 67/8
10x/6 = 67/8
5x/3 = 67/8
5x * 8 = 67 * 3
40x = 201
x = 201/40
   = 5 1/40 inches
So the amount of rainfall in September in Washinton is 5 1/40 inches.

The debate team is showing a video of their recent debate. The first showing begins at 3:15 p.m. The second showing is scheduled
vova2212 [387]
No OK let's see how long Is the debate, the second debate started 20 late then it started at 5:10 so to know the length of the debate we should subtract the 2 shows so 5:10-3:15 = 1:55 minutes we also should subtract 30 m because of the break so 1:55-30 = 1:25 minutes so the show length is 1:25 minutes so to know when the 2nd show will end we should add 5:10+1:25 = 6:35 p.m
