You reduce by since they are even number you divide each by 2, 2:40, if you can still divide then do so, it simplifies to 1:20
You need to use the quadratic formula or graph it and find the zeros. that does factor cleanly
deion has the following data: 47, u, 41, 38. if the range is 10 which could "U" be ?
REmember that
The range of a set of data is the difference between the highest and lowest values in the set
If U is the highest value
Range=U-38
range=10
so
10=U-38
U=10+38
U=48
If U is the lowest value
Range=47-U
10=47-U
U=47-10
U=37
therefore
U coulbe between 48 and 37
Absolute value so the answer can be positive or negative
R+3>7
-3>-3
R>4
Or
R-3>7
+3>+3
R>10
