Answer:
r = -0.02
Explanation:
r = 0 signifies no correlation. r = -0.02 is closest to 0 than the other choices.
Answer:
Option 2 would be the best answer
Step-by-step explanation:
![a ^{2} - b ^{2} = (a + b)(a - b)](https://tex.z-dn.net/?f=a%20%5E%7B2%7D%20%20-%20b%20%5E%7B2%7D%20%20%3D%20%28a%20%2B%20b%29%28a%20-%20b%29)
In this case, a= 3x and b= 4
Since there is a power 2, it is a quadratic equation not a linear equation.

Answer:
The answer would be D, because it all depend on the quantity.
Step-by-step explanation:
1. SOH CAH TOA tells you the tangent is the ratio of the Opposite side to the Adjacent side, that is, 4/3. (This correct answer is not among your choices.)
2. The mnemonic SOH CAH TOA can be helpful here. It tells you
... Sin = Opposite/Hypotenuse
... Cos = Adjacent/Hypotenuse
... Tan = Opposite/Adjacent
![\dfrac{c}{b}=\tan{C}\\\\ \dfrac{b}{a}=\sin{B}\\\\ \dfrac{b}{c}=\tan{B}\\\\ \dfrac{c}{a}=\cos{B}](https://tex.z-dn.net/?f=%5Cdfrac%7Bc%7D%7Bb%7D%3D%5Ctan%7BC%7D%5C%5C%5C%5C%20%5Cdfrac%7Bb%7D%7Ba%7D%3D%5Csin%7BB%7D%5C%5C%5C%5C%20%5Cdfrac%7Bb%7D%7Bc%7D%3D%5Ctan%7BB%7D%5C%5C%5C%5C%20%5Cdfrac%7Bc%7D%7Ba%7D%3D%5Ccos%7BB%7D)
3. Reference the ratios listed above (for the second problem). You see that sin(α) = cos(90°-α). That is, the sine of an angle is the cosine of its complement and vice versa. The appropriate choice is
