Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the parts of the ratio, 3 + 3 + 6 = 12 parts
Divide 180° by 12 to find the value of one part of the ratio
180° ÷ 12 = 15° ← value of 1 part of the ratio, thus
3 parts = 3 × 15° = 45°
6 parts = 6 × 15 = 90°
Hence
∠X = ∠Y = 45° and ∠Z = 90°

Step-by-step explanation:
Given:
Mean = 45
Standard deviation = 9
Confidence level = 95%.
To find:
The confidence interval.
Solution:
The formula for confidence interval is:
Where, is mean, z is the z-value at given level of confidence, is the standard deviation and n is the number of observations.
The z-value at 95% confidence level is 1.96.
Here number of observations are not given. Assume it is 1.
Putting .
It can be written as
Approximate the value to the nearest whole number.
The interval for the middle 95% of snowfall is 27 to 63.
Therefore, the correct option is A.
