Answer:
→ Mean of given data = xi = (86 + 49 + 63 + 90 + 82 + 98 + 36) / 7 = 504 / 7 = 72 .
→ variance of the set of data = 525

The regular octagon has eight equal sides. Then the area of the regular octagon of side length be 4.6 is 102 ft².
<h3>What is a regular octagon?</h3>
It is a polygon that has eight equal sides. In a regular octagon, the opposite sides are parallel. And its diagonals are also equal and intersect at mid-point.
Given
A regular octagon has a radius of 6 ft and a side length of 4.6 ft.
We know the formula for the regular octagon.
Area of the regular octagon = 2(1 + ) a²
Where a be the side of a regular octagon.
Then the area of the regular octagon will be.
Thus, the area of the regular octagon of side length be 4.6 is 102 ft².

10(17 + 4) + x =230
170 + 40 + x =230
210 + x = 230
Subtract 210 from both sides.
x = 20
10(17 + 4) + 20 = 230
5000 is 1/10 of what number....
5000 = 1/10x
5000 / (1/10) = x
5000 * 10/1 = x
50,000 = x <=== ur number
