The answer is Angle BCA. I’m pretty sure
Answer:
(10, -20).
Step-by-step explanation:
y= -5x + 30
x = 10
Substitute x = 10 in the first equation:
y = -5*10 + 30
y = -50 + 30
y = -20.
So the solution is (10, -20).
Answer:
40 hours a week for two weeks
Step-by-step explanation:
If Ray is being paid the same, he would make more money from working 40 hours for two weeks. That would be a total of 80 hours while the 32+46 is only 78 hours.
Answer:

And the real value for this case is y=14. The residual is defined as:

Replacing we got:

And the best answer would be:
-2
Step-by-step explanation:
For this case we know that the best fit line for the relationship between x and y is given by:

And we know that an individual in the dataset has a score of 10 on the x-variable and a score of 14 on the y-variable. So then we can find the estimated value like this:

And the real value for this case is y=14. The residual is defined as:

Replacing we got:

And the best answer would be:
-2
