The two angles on top are supplementary angles meaning they should add up to 180
72+3x=180
3x=180-72
3x=108
x=36
Mark me brainliest!
Answer:
Add '6y' to each side of the equation. 5x + -6y + 6y = 0 + 6y Combine like terms: -6y + 6y = 0 5x + 0 = 0 + 6y 5x = 0 + 6y Remove the zero: 5x = 6y Divide each side by '5'. x = 1.2y Simplifying x = 1.2y.
Step-by-step explanation:
Just input 3550 for (c) then for the second question input 24 for c times 50 +1900.
A). 33
B). 3100
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
