Answer:
130
Step-by-step explanation:
first find angle C, which is 180-90-40=50
angle Y=180-50=130
Answer:
graph two points at the coordinates (-6, 0) and the coordinates (-8, 3), and make a line through them.
Step-by-step explanation:
First simplify. 2x+3y= -18., -----------> 3y= -2x -18., ---------> y= -2/3x -6
To graph this you would first go to the coordinates (-6, 0) and put a point there. Next, you would go to the coordinates (-8, 3) and put a point there. Then make a line and you are done. That should be right.
Answer:
ABC =132
Step-by-step explanation:
The two angles form a straight line so they add to 180
ABC + 48 = 180
Subtract 48 from each side
ABC +48-48 = 180-48
ABC =132
Answer:
23.2586 ; IQ ; hours spent studying per week
Step-by-step explanation:
Given the regression model:
y = 6.9+0.055x1 +0.107x2 + 0.0853X3.
IQ scores = (X1)
Hours spent studying each week = (X2),
one's high school average = (x3)
The multiple standard error is 6.313 and R^2=0.826.
What is the predicted GPA for a student with a IQ of 108, 32 hours spent studying per week and a high school average of 82?
X1 = 108 ; X2 = 32 ; X3 = 82
y = 6.9 + 0.055(108) + 0.107(32) + 0.0853(82)
y = 23.2586
B.
The Independent variable with the smallest effect on GPA is the variable with the smallest Coefficient, which is IQ with a Coefficient of 0.055
C.
The Independent variable whiae unit change has the greatest effect on GPA is X2, hours spent studying per week as it has the highest Coefficient of all independent variables with a Coefficient value of 0.107.
