Let's simplify step-by-step.
14xy+3xy+2x(y−17)
=19xy−34x
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:
sentence number 2
Step-by-step explanation:
Well we set the perimeter to 120 feet.
This means that 2x+2y=120
Now we know the area of a rectangle is xy so we have to solve for both x and y in the perimeter equation.
2x=120-2y
x=60-y
2y=120-2x
y=60-x
Now we plug these values into our area equation A=xy to get:
A=(60-y)(60-x)
