Answer:
Step-by-step explanation:
You can obtain the regression equation using minitab software ...
First step:
Choose stat then select regression and regression
Next step:
In Response, enter the column containing the response (Y) variable as Cost.
Next step :
In Predictors, enter the columns containing the predictor (X) variables as Summated Rating.
Final step :Click OK.
Then you get your answer
Answer:
60 is the answer
Step-by-step explanation:
10x - 20 = 7x + 4 (Corresponding angles)
10x - 7x = 20 + 4
3x = 24
x = 8
substituting the values,
10(8) - 20
80 - 20
60
similarly the other angle is 60 since they are corresponding angles.
In order to be parallel to your line, a line has to have the same slope as your line. So it has to have slope −4

.
Thus any line parallel to the line =−4+5

I don't know about the first one but the second one is 34.9°. It would be that because are right angles add up to 90° and if you subract 55.1 and 90 it would equal 34.9. But this rule only works on right angles.
