Answer:
(3; 180°)
Step-by-step explanation:
The point (-3, 0) is located on the -x axis at a distance of 3 units from the origin. The -x axis is at an angle of 180° CCW from the +x axis. So, the polar coordinates are ...
r = 3
θ = 180°
This might be written as ...
(r; θ) = (3; 180°) = (3; π radians)
Assuming this is a triangle then the answer would be 10 but that's not an option. If you gave me more information or confirmed what shape I'm dealing with I may be able to help you.
Answer: -0.64
Step-by-step explanation:
We know that the coefficient of determination in a simple linear regression model is denoted by 
, which gives the proportion of the variance in the dependent variable that is predictable from the independent variable.
Given, the coefficient of determination in a simple linear regression model is 64%.
i.e.
As there is negative relation between the dependent and independent variables.
Then, the correlation coefficient = -0.64
Answer:
The solution is attached below:
Step-by-step explanation:
k=-3 Try using a technique DLAM, Distributive property,like terms, Add/subtract (if its positive,make it a negative) and variables (divide your result from the last step.)
