Yes her number line make sense in why is because the way she sat it up was the right way..
Perimeter = 2w + 2l
Since its a square, the length and width are equal therefore:
2(s + 3) + 2(s + 3) = Perimeter
You can simplify this into a variety of ways:
1. 4(s + 3)
2. 2s + 6 + 2s + 6
3. 4s + 12

Answer:
The standard deviation of a probability distribution is a measure of variability of the distribution.
Step-by-step explanation:
We have been given an incomplete statement. We are asked to complete the given statement.
We know that standard deviation is measure of variability or dispersion of a set of data values.
It tells up how much a data point is spread out from the average or mean of the data set.
