The median is the value that is in the middle of a dataset.
The first step to find the median is to order the values from least to greatest:
7, 8, 11, 12, 13, 15.
Since the number of data is even, the median will be the average of the pair of values that is in the middle, in this case, 11 and 12:

The median of the data set is 11.5.
Answer:
θ = π n + π/2 for n element Z
Step-by-step explanation:
Solve for θ:
1 + 2 cos(2 θ) + cos^2(2 θ) = 0
Write the left hand side as a square:
(cos(2 θ) + 1)^2 = 0
Take the square root of both sides:
cos(2 θ) + 1 = 0
Subtract 1 from both sides:
cos(2 θ) = -1
Take the inverse cosine of both sides:
2 θ = 2 π n + π for n element Z
Divide both sides by 2:
Answer: θ = π n + π/2 for n element Z

Answer:
-2.5
Step-by-step explanation:
Answer: is 0.001
10^-3 = (1)/(10^3) move the negative exponent to the denominator (1)/(1000) simplify 10^3 in the denominator (1)/(1000) = 0.001
