it is -5/12 just * the numbers
Given a data on the relationship between the number of students that have ever gone snowboarding and <span>the number of students that own a skateboard.</span>
Given from the survey that <span>35
of the 99 students who own a skateboard have snowboarded and there
were 13 students who have snowboarded but do not own a skateboard, and
147 students who have never gone snowboarding and do not own a
skateboard.
We represent the above information in a two</span> way frequency table.
Have Snowboarded Never Snawboarded Total
Skateboard 35 64 99
No Skateboard 13 147 160
Total 48 211 259
Answer:
314 in² (nearest whole number)
Step-by-step explanation:
<u>Radius of a regular polygon</u>: The distance from the <u>center</u> of the polygon to any vertex. The radius of a hexagon is equal to the length of one side.
Therefore, from inspection of the given diagram:
- radius = 11 in ⇒ side length = 11 in
To find the area of a regular polygon, we first need to calculate the apothem. The <u>apothem</u> is the line drawn from the center of the polygon to the midpoint of one of its sides.

where:
- s = length of one side
- n = number of sides
Given:
Substitute the given values into the formula and solve for a:

<u>Area of a Regular Polygon</u>

where:
- n = number of sides
- s = length of one side
- a = apothem
Given:
Substitute the given values into the formula and solve for A:



You can start with the form
∆y(x -x1) -∆x(y -y1) = 0
Here, we have
∆y = 11-(-3) = 14
∆x = -3-1 = -4
and we can choose (x1, y1) = (1, -3). This gives
14(x -1) -(-4)(y -(-3)) = 0
14x +4y -2 = 0
All these terms have a common factor of 2 that we can remove. Adding 1 to the result puts it in standard form:
7x +2y = 1
