Answer: True
This is because, the intercept is the expected mean value of Y when x is equal zero. If x is never zero; that is, no data value is near x equal zero, the regression has little meaning. There is no interest in the regression.
Answer:
-6=7 NO SOLUTION
Step-by-step explanation:
First, distribute the -3 to the (k +2)
Your equation becomes, -3k-6=-3k+7
Add 3k to both sides to have the variables be on the same side
Your equation becomes, -6=7
Since that isn’t true, it’s a no solution
I hope this helps!
Answer:
Step-by-step explanation:
I'll focus on problem 19 and problem 22
============================================================
Problem 19
Answers:
-------------------------------
Explanation:
The horizontal lines are parallel. Note the arrow markers along the interior portion of the lines. These similar markers tell us how the lines pair up to be parallel to one another.
Since the horizontal lines are parallel, this means the angles in question are congruent. They are corresponding angles.
x+15 = 102
x = 102-15
x = 87
Which leads to
x+15 = 87+15 = 102
============================================================
Problem 22
Answer: y = 27
-------------------------------
Explanation:
We have a pair of alternate exterior angles. They are congruent due to the parallel lines.
Let's solve for y.
7y-55 = 3y+53
7y - 3y = 53+55
4y = 108
y = 108/4
y = 27
I am not sure but i think the slope is a line on a graph like posative negetive zero and undifined.
