Given:
Standard error = 4
Population standard deviation = 16
To find:
The value of n.
Solution:
The formula of standard error is:
Where, SE is standard error , is population standard deviation and n is the total number of elements.
Substituting in the above formula, we get
Taking square on both sides, we get
Therefore, the value of n is 16.
The answer is C. This is because the area of a cylinder can be represented with the formula:
Then, you substitute 6 for h, the height, and 3.5 for r, the radius and solve, giving you the answer, 208.92 sq. cm. Then, you have to subtract the two circular sides. You find the area of one circle and multiply by 2. One circle is 38.48 sq. cm and doubled is 76.96 sq. cm. Then you subtract 208.92-76.96 giving you about 132 sq. cm.
Answer:
Point O is the center of the circle.
<u>Part (a)</u>
is a chord.
is a segment of the radius and is perpendicular to
If a radius is perpendicular to a chord, it bisects the chord (divides the chord into two equal parts).
Therefore,
<u>Part (b)</u>
If was extended past point E to touch the circumference it would be a chord.
As is perpendicular to , it would bisect the chord, but as is only a portion of a chord, <u>does not</u> bisect .
Therefore, there is no length equal to .
