Answer:
16.9 units
Step-by-step explanation:
Sometimes the easiest way to work these problems is to get a little help from technology. The GeoGebra program/app can tell you the length of a "polyline", but it takes an extra segment to complete the perimeter. It shows the perimeter to be ...
14.87 + 2 = 16.87 ≈ 16.9 . . . units
_____
The distance formula can be used to find the lengths of individual segments. It tells you ...
d = √((Δx)² +(Δy)²)
where Δx and Δy are the differences between x- and y-coordinates of the segment end points.
If the segments are labeled A, B, C, D, E in order, the distances are ...
AB = √(5²+1²) = √26 ≈ 5.099
BC = √(1²+3²) = √10 ≈ 3.162
CD = Δx = 3
DE = √(3²+2²) = √13 ≈ 3.606
EA = Δy = 2
Then the perimeter is ...
P = AB +BC +CD +DE +EA = 5.099 +3.162 +3 +3.606 +2 = 16.867
P ≈ 16.9

Answer:
a. the less variability it has
Step-by-step explanation:
The standard deviation is a measure of the amount of variation or dispersion of a set of values.
When your standard deviation is big your data is more dispersed.
When your standar deviation is small your mean is a representative index of your data, and there is less variability.
If there was no dispersion of the data (if all your data be the same) then the standard deviation will be 0.
<u><em>Answer:</em></u>
Option 3
<u><em>Explanation:</em></u>
<u>To get the value of the cheapest bike, best option, we will calculate the total cost of each bike:</u>
<u>i- Option 1:</u>
Total cost = $88
<u>ii- Option 2:</u>
$5 down payment and $8 per week for 10 weeks
Total cost = 5 + 8(10) = 5 + 80 = $85
<u>iii- Option 3:</u>
$12 down payment and $5 per month for 12 months
Total cost = 12 + 5(12) = 12 + 60 = $72
<u>iv- Option 4:</u>
$20 down payment and $20 per month for 12 months
Total cost = 20 + 20(12) = 20 + 240 = $260
<u>Now, from the above calculations, we can conclude that:</u>
The best price would be that of option 3 ($72). It is the lowest price compared to other option.
Hope this helps :)
