Answer:
Range: 36
Variance: 103.69
Standard Deviation: 10.18282868
Step-by-step explanation:
Because we were not told otherwise I think it would be fair to say that everything has an equal probability
Let's start by finding the range
the range is the largest value minus the smallest
40-4=36
Let's then find the variance
the variance is the second moment minus the first moment squared
first moment: .1(10+9+5+7+5+6+4+6+7+40)= 9.9
second moment: .1(10²+9²+5²+7²+5²+6²+4²+6²+7²+40²)= 201.7
201.7-9.9²= 103.69
The standard deviation is simply just the square root of the variance
√(103.69)= 10.18282868
not sure what they meant by the rounding part so I'll leave that to you
Based on the indices of the regular polygons, the number of sides that X has is 8. See the computation below.
<h3>What is the analysis for the above solution?</h3>
Assuming that X has G number of sides; and
Y has H number of sides, this means that:
G-H = 3 ...........1
Recall that the formula for the exterior angles is:
360/n; where n is number of sides
X = 360/G
Y = 360/H
(360/G) + (360/H) = 117°.......2
Solving 1 and 2 simultaneously, we obtain:
G= 8 and
H = 5
Thus, X has 8 sides.
