Arctan (√3 /3) = 30°. = π/6 rad
That is the value searched, in degrees and radians.
You can verifiy that tan(30°) = sin(30°) / cos(30°) = [1/2] / [√3/2] = 1/√3 = √3 / 3
Answer:
Variance s2 = 788.33333
Standard Deviation s = 28.077274
Count n = 7
Mean x¯¯¯ = 52
Sum of Squares SS = 4730
Step-by-step explanation:
Put all numbers in smallest to largest order
if there are an odd number of results, the median is in the middle
if there even, then its the mean of the two central numbers
To do this problem, you gotta cross-multiply. SO,
multiplied by
12 times 14 = 168
21 times 3 = 63
Then the final answer is
