The empirical rule for a normal distribution states that 95% of the data points lie within plus and minus two standard deviations from the mean. 30 is two standard deviations below the mean and 42 is two standard deviations above the mean.
Therefore, 95% if the employees are between 30 and 42 years old.
Answer:
Angle between two tangents or two secants is the half of the difference of intercepted arcs.
#1
- x = 1/2(250° - (360° - 250°)) = 1/2(250° - 110°) = 1/2(140°) = 70°
#2
- 50° = 1/2(170° - x)
- 100° = 170° - x
- x = 170° - 100°
- x = 70°
