<span>The standard deviations of 99.1 centimeters and 0.991 meters are equivalent lengths.
The meter measurements will have less variation because of the numbers the variance will be 1m for every 100cm. But the coefficient variation will be the same for both.

1/8 multiplied by 2 will give you 16/8
Answer:
6.4 - x
Step-by-step explanation:
Positive difference is the bigger number- the smaller number
Negative difference is the smaller number- the bigger number
In this case, we do not know which is bigger so it is advisable to go for the known number- the unknown number. that is 6.4 - x
Option A. The angles do not have the same reference angle.
Explanation:
1) <u>Angle 5π / 3 radians:</u>
- Convert radians to degrees: 5π/3 × 180° / π = 300°
- 300° is in the fourth quadrant
- The reference angle for angles in the fourth quadrant is 360° - angle ⇒ 360° - 300° = 60°.
- ∴ The reference angle for this angle is 60°.
2) <u>Angle 5π / 6 radians:</u>
- Convert radians to degrees: 5π/6 × 180° / π = 150°
- 150° is in the second quadrant
- The reference angle for angles in the second quadrant is 180° - angle ⇒ 180° - 150° = 30°.
- ∴ The reference angle for this angle is 30°.
3) <u>Conclusion</u>:
- Since the reference angles are different, the tangent ratios have different values.
- tan (5π/3) = - tan(60°) = - √3
- tan (5π/6) = - tan(30°) = - (√3)/3
Note that the tangent is negative in both second and fourth quadrants.
I believe it is 1/9,2/9,4/9,8/9 etc just keep doubling the numerators
