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:
(- 1, - 6 )
Step-by-step explanation:
Under a counterclockwise rotation about the origin of 270°
a point (x, y ) → (y, - x ), thus
(6, - 1 ) → (- 1, - 6 )
Answer:
The formulas are functionally the same, but 'n' (the sample size) is used instead of 'N' (the population size).
Step-by-step explanation:
The sample mean is the average value for a set of observations which is derived from a population. While the population mean is the average value for the entire set of observation belonging to a particular study of interest.
The set of observation belonging to a population is denoted by 'N' ; while the sample size is denoted as 'n' :
The mean formula is written thus :
Population mean = Σx / N
Sample mean = Σx / n
Where, x = set of values.
Answer:
g = 3/7
Step-by-step explanation:
7/(3/2)
= 7 x (2/3)
= ( 2 x 7 )/3
= 14/3
14/3 = 2/g
Cross multiply,
14 x g = 3 x 2
g = ( 3 x 2 )/14
14 can be written as 2 x 7.
g = ( 3 x 2 )/( 2 x 7 )
2 in both numerator and denominator gets cancelled.
g = 3/7
