Answer:
True
Step-by-step explanation:
The Interquartile Range (IQR) is a more robust measure of variability because it excludes outliers from the distribution. Due to this fact, the IQR works with only 50% of the central data excluding the outlying values in the data set from its calculation.
The variance is affected by outliers, and the Range is way more affected by only the first and the last observation.
So, yes the IQR is the least influenced. Therefore, a more robust measure of variability.
Answer:
The angles are adjacent. x=20
Step-by-step explanation:
The angles should add up to 180 because they are supplementary.
7x+x+20=180
8x+20=180
180-20=160
8x=160
x=20
It is 1/6 because you only have 6 beads in total meaning that you have a one out of 6 chance of pulling out the yellow bead
