If there are outliers, IQR is a better measure of the spread of data than range. The range will include the outliers, and make the data appear to have many more terms of a greater/lesser value than it has in reality. IQR shows the middle 50%, which (usually) doesn't contain outliers, so the majority of the data spread would be shown by IQR in a data sample with a significant amount of outliers. If your measure of the spread of data contains outliers, then the measure isn't accurate.
im sorry I want to help but it wouldnt load :'(
Answer:
A
Step-by-step explanation:
The square root of 50 is less than the square root of 78.
You flip the signs when you are dividing by a negative value.
-2x+3>15
-2x>15-3
-2x>12
x<12/-2
x<-6
Now to test this
Try putting x in the original equation when it is -5.
-2(-5)+3>15
10+3>15
13>15
This is false because our answer says x is less than -6.
Now any value less than -6 will work so let's go with -7.
-2(-7)+3>15
14+3>15
17>15
This result is True.
Hope this helps out!
