Answer:
m∠CPD = 129.75°
Step-by-step explanation:
m∠APD + m∠APB = 180 since the angles are supplementary
x + 1 + 3x - 18 = 180
4x - 17 = 180
4x = 197
x = 49.25
m∠APB = 3(49.25) - 18 = 129.75
m∠APB = m∠CPD because the angles are vertical angles
m∠CPD = 129.75°
Answer:
False
Step-by-step explanation:
Given that two linear regression models have the same number of explanatory variables
First model has coefficient of determination as 0.45 while other
0.65
we know that R^2 is the proportion showing the variation of dependent because of variation in independent variables.
Hence a higher R square is always better because it ensures more linearity and hence more accuracy in the regression equation.
Hence 0.65 model is better than 0.45 model.
The given statement is false.
Answer:
C. y = -9, -3, 0, 5, 7
Step-by-step explanation:
The given function is represented by the set of ordered pairs
{(-2,0,) (-4, -3,) (2, -9,) (0,5,) (-5,7)}
The range of this function is the set of all the y-values.
The set of the y-values are:
{-9,-3,0,5,7}
Therefore the range is y = -9, -3, 0, 5, 7
The correct option is C
