It means the scatter plot is a line with negative slope. The relation is perfectly described by a linear equation.
Answer:
C
Step-by-step explanation:
Okay, the catch of this question is that they do a very good job of explaining Maria's age in terms of George's age, but they leave George's age in terms of Maria's all up to you.
First start off by doing an expression of what they explicitly give you. Maria's age in terms of George's age.
Let's use variables g, representing George's age and m representing Maria's age
m = 2g + 3
Okay, this is all dandy and all, but they ask us for George's age in terms of Maria's, so we need to isolate for g.
subtract the 3 from both sides, like so:
m - 3 = 2g
then divide 2 from both sides: (remember we're dividing the whole thing)
(m-3)/2 = g
Now we have an expression for George's age in terms of Maria's.
g = (m-3)/2 or 
The answer that gives us this, is C.

Answer:

Step-by-step explanation:
sin(theta) is positive
tan(theta)=sin(theta)/cos(theta) is negative
If sin(theta) is positive and tan(theta) is negative, then cos(theta) is negative because +/-=-
So we are looking for the quadrant where sine is positive and cosine is negative or when x is negative and y is positive.
This is in quadrant 2 so our angle theta is between 90 and 180 degrees.
