Answer:

-4

Step-by-step explanation:

To identify the media, you have to:

''Arrange your numbers in numerical order.

Count how many numbers you have.

If you have an odd number, divide by 2 and round up to get the position of the median number.

If you have an even number, divide by 2. Go to the number in that position and average it with the number in the next higher position to get the median.''

If we follow the steps, the answer should be -4. With 9 data values, the middle number is the data value at position 5. And position 5 is -4. So the answer will be -4. Hope this helps !

Green:

This is a circle with center (h, k) at (-2,-2) and radius (r) = 1

Formula: (x - h)² + (y - k)² = r²

Answer: (x + 2)² + (y + 2)² = 1

Purple:

This is an ellipse with center (h, k) at (0,-2) and radius on the x-axis (a) = 3 and radius on the x-axis (b) = 1

Formula: $\frac{(x-h)^{2}}{a^{2}} +\frac{(y-k)^{2}}{b^{2}}=1$

Answer: $\frac{x^{2}}{9} +(y+2)^{2}=1$

An angle whose measure is _____ is rotated more than halfway around a circle

zaharov [31]

The correct answer is 60⁰.

Step-by-step explanation:

An angle whose measure is 60⁰ is rotated more than halfway around a circle.
Since, we have to find the measure of angle.
As we already know that the angle of rotation about a circle is 360° therefore we have to find more than halfway of this angle.

Considering that an angle is rotated more than halfway around a circle be $\frac{1}{6}$

Multiplying $\frac{1}{6}$ with 360⁰
Therefore, it can show as $\frac{1}{6}$ ×360⁰
Which gives the result to be 60⁰
Hence, when an angle is measured 60⁰, it is rotating more than halfway around a circle.
A single rotation around a circle is equal to 360 degrees.
The measurement of an angle shows the magnitude and direction of the rotation of the angle from its initial position to the final position.
If the rotation is in a counterclockwise direction, it has an angle with positive measure. If the rotation is clockwise, it has an angle which gives negative measure.
