4 times the measure of the complement of an angle is equal to 2/3 the measure of the original angles supplement. what is the mea
Irina-Kira [14]
Let angle be x 
4 times complement = 4(90 - x)
2/3 times its supplement = 2/3(180 - x)

4(90 - x) = 2/3 (180 - x)
360 - 4x = 120 - 2/3 x
240 =  3 1/3 x
x =  240  /  10/3  = 240 * 3/10  = 72 degrees Answer

What conclusion can be made when r, the correlation coefficient between two variables, is 0?
IgorLugansk [536]
The correlation coefficient between two variables, r, is always going to be between -1 and 1.

- If the correlation coefficient is 0, means that there is no strong correlation relationship in one direction or the other direction. 
- If the correlation coefficient is -1, means that these two variables move in opposite directions.
- If the correlation coefficient is 1, means that these two variables move in the same direction.
