A) d+q=20
0.1d+0.25q=4.40 Let's just read what this says: first, # of dimes (d) plus # of quarters (q) is 20.The second equation can be called the VALUE EQUATION; it says that one tenth of a dollar ($0.10) times the # of dimes is part of the total monetary value, and that one quarter of a dollar ($0.25) times the # of 'quarter' coins is the other part of this stash, and it totals $4.40. VOTE FOR A.

The results of a linear regression are shown below.
IgorLugansk [536]

Hello!

As we can see, our a value, which would be the coefficient of x, which determines our slope, is negative, meaning that this whole line is negative.

Furthermore, the correlation can be determined using the r value of the linear regression, which is around -0.9.

If the r value of the linear regression is close to 1 or -1, let's say around |r| > 0.8, then we can consider the regression a strong correlation, meaning that this is a strong negative correlation, which is answer choice A.

What is | -7.9 ?<br> help
Tamiku [17]
I think you mean |-7.9| which is the absolute value of 7.9
Absolute value just means how far away it is from zero on a number line.
So the value is always positive. So the positive of -7.9 is 7.9
|-7.9|= 7.9
Good luck!
