1. The value of x is greater than of equal to 1250 and less than or equal to 1300.
i.e.,
...(1)
2. The value of x is greater than of equal to 1300 and less than 1350.
i.e.,
...(2)
On combining (1) and (2), we get

Interval notation is
.
Therefore, the error interval for x is
.
Given that, according to sanitation departments report; the samount of garbage produced by 1 resident

It would be: k+3 = 10
subtracting 3 from both sides,
k+3-3 = 10-3
k=7
It would be thirty six seconds over one-fourth mile= 144 miles per hour
If the data set represents the number of rings each person is wearing, being: 0,2,4,0,2,3,2,8,6, the interquartile range of the data is 2. Being, 4 as the Q1, 3 as the Q2 or median, and 6 as the Q3. Where the formula of getting the interquartile range is IQR= Q1-Q2.
