theta = pi/6 and
theta = 5pi/6
Step-by-step explanation:
see image. Factor the expression. Solve for sin theta. Then use a calculator or unit circle to solve for theta. See image.
Answer:
Min value = 62
Lower quartile = 69
Median = 75.5
Upper quartile = 80
Max value = 83
Outlier = 118
Step-by-step explanation:
Order the data from smallest to largest:
62, 63, 64, 69, 72, 75, 75, 76, 78, 78, 80, 82, 83, 118
The median (Q2) value is the middle value.
As the middle is between the 7th and 8th values,
median = (75 + 76) / 2 = 75.5
Lower quartile (Q1) = 4th value = 69
Upper quartile (Q3) = 11th value = 80
IQR = Q3 - Q1 = 80 - 69 = 11
Outliers < Q1 - 1.5 x IQR = 69 - 1.5 x 11 = 52.5
Outliers > Q3 + 1.5 x IQR = 96.5
Therefore, one outlier at 118
Minimum value = 62
Maximum value = 83 (as 118 is an outlier)
