1 answer:
The standard deviation<u> </u><u>INCREASES</u>
Step-by-step explanation:
Standard deviation is used to show how the points of the data deviate from the mean. The formulae for deriving standard deviation is attached. As seen from the formulae, the greater the variance of the data from the mean, the higher the Standard Deviation.
The mean of the given data points is $103.4. $450 is way off from this mean meaning that there is a large variance in this data point.

The given two polygons are similar to one another ~
Sides of the given polygons are in ratio of :
to put in simple Ratio ~
So, the sides of the larger polygon are :
- 4 × 7 = 28
- 6 × 7 = 42
- 3 × 7 = 21
- 4 × 7 = 28
- 7 × 7 = 49
- 3 × 7 = 21
- 3 × 7 = 21
- 4 × 7 = 28
Now, to find the Perimeter of larger polygon ~ add the side length of all sides :
