Find the correlation coefficient of the height and weight

1 answer:

7 0

The correlation coefficient (r) of the height and weight is 0.40391008.
Rounded, It will be 0.4
That means that the correlation between the height and weight is a positive weak correlation.

What is the period of y = 8 cos (5pie x + 3pie/2)-9 Give an exact value. Units

zzz [600]

$\\ \rm\Rrightarrow y=Acos(Bx+C)+D$

This is the general formula and the period is 2π/B

Now our given function

$\\ \rm\Rrightarrow y=8cos\left(5\pi x+\dfrac{3\pi}{2}\right)-9$

On comparing we get

A=8
B=5π
C=3π/2
D=-9

Period:-

$\\ \rm\Rrightarrow \dfrac{2\pi}{B}$

$\\ \rm\Rrightarrow \dfrac{2\pi}{5\pi}$

$\\ \rm\Rrightarrow \dfrac{2}{5}$

What values for θ (0 ≤ θ ≤ 2pie ) satisfy the equation?

svetoff [14.1K]

Factor out the cosθ:
cosθ (2sinθ + sqrt3) = 0
Therefore, the only ways this can happen are if either cosθ = 0 or if (2sinθ + sqrt3) = 0
The first case, cosθ = 0 only at θ = pi/2, 3pi/2.
The second case, (2sinθ + sqrt3) = 0 simplifies to:
sinθ = (-sqrt3)/2
θ = 4pi/3, 5pi/3
Therefore the answer is A.
