Answer:
1/9
Step-by-step explanation:
Mean = (8 + 9 + 10 + 16 + 17) / 5 = 60/5 = 12.
x - mean:
8 - 12 = -4, -4² = 16
<span>9 - 12 = -3, -3² = 9
</span>
<span>10 - 12 = -2, -2² = 4
</span>
<span>16- 12 = 4, 4² = 16</span>
<span>17- 12 = -5, -5² = 25
</span>
Sum of the squares = 16 + 9 + 4 + 16 +25 = 70
Variance = 70/5 = 14
Variance = 14
The height would be 13.5in
Answer:
or 3.14
Step-by-step explanation:
The formula for the area of a circle is 
If this quarter circle were to be a full circle, the area would be 
Since this is a quarter circle as the angle is 90 degrees (which is a quarter of 360), the area of this shape is
.
<h3>
Answer: 125 m^3</h3>
Work Shown:
V = (area of base) * (height)
V = B*h
V = 25*5
V = 125 m^3
The volume of the prism is 125 cubic meters.
