Mean is the "meanest" because it requires the most work. Add up the values in your data set and divide by the number of terms in the data.
Let x represent attendees at Harry's Hoedown, then
Mean =
41 =
123 = 48 + 33 + x
123 = 81 + x
42 = x
Answer: 42
Answer:
case a) The approximate circumference of circle is and the ratio of circumference to Diameter is
case b) The approximate circumference of circle is and the ratio of circumference to Diameter is
case c) The approximate circumference of circle is and the ratio of circumference to Diameter is
Step-by-step explanation:
we know that
The approximate circumference of each circle, is equal to the perimeter of each inscribed polygon
case A) the figure is an inscribed pentagon
step 1
Find the approximate circumference of circle
The perimeter of the pentagon is equal to
where
substitute
therefore
The approximate circumference of circle is
step 2
Find the ratio of circumference to Diameter
we know that
The radius is half the diameter so
The ratio is equal to
case B) the figure is an inscribed hexagon
step 1
Find the approximate circumference of circle
The perimeter of the hexagon is equal to
where
substitute
therefore
The approximate circumference of circle is
step 2
Find the ratio of circumference to Diameter
we know that
The radius is half the diameter so
The ratio is equal to
case C) the figure is an inscribed dodecahedron
step 1
Find the approximate circumference of circle
The perimeter of the dodecahedron is equal to
where
substitute
therefore
The approximate circumference of circle is
step 2
Find the ratio of circumference to Diameter
we know that
The radius is half the diameter so
The ratio is equal to
<em>Conclusion</em>
We know that
The exact value of the ratio is equal to
The approximate value of the circumference will be closer to the real one when the number of sides of the inscribed polygon is greater
