Answer: 0.4016
Step-by-step explanation:
Let x be a random variable that represents the height of women in a country.
Mean : inches
Sample size : n= 65
Standard deviation:
The probability that the mean height for the sample is greater than 65 inches =
Hence, the probability that the mean height for the sample is greater than 65 inches = 0.4016
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
- Multiplying
with 360⁰
- Therefore, it can show as
- 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.
