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.
I don’t see no options? But if you simplify the answer is -30x^2 - 4x + 8 hope it helps
Mid segment = (1/2)base
12.5 = (1/2)* base
Multiply both sides by 2
25 = base
Letter b
Answer:
The correct answer is C. The meal costed $1.30.
Step-by-step explanation:
Since the student bought his sandwich for 80 cents, his milk for 20 cents and his cake for 30 cents, to determine the total amount to pay we must add these values. Thus 80 + 20 + 30 gives a total of 130 cents. In this regard, the American monetary system establishes that 100 cents are equal to one dollar, with which the 130 cents would become 1 dollar with 30 cents, that is, $ 1.30.
