Properties of Correlation Coefficient,
1- A positive correlation means that if one variable gets bigger, the other variable tends to get bigger.
2- A negative correlation means that if one variable gets bigger, the other variable tends to get smaller.
As in this graph x increases y gets decreased, so it is a negative co-relation. And the points are scattered more the line, so it is a moderate negative co-relation graph. (Please follow the attached picture herewith)
Answer:
4
Step-by-step explanation:
She can use a dime and a quarter to buy one package. With 3 dimes and more than 3 quarters, she can buy 3 packages this way.
She can use 2 nickels and a quarter to buy one package. With 2 nickels and the 2 remaining quarters, she can buy 1 package this way.
Mae-Ying can buy 4 packages, and will have 1 quarter left over.
_____
You can add up her money and divide by 35¢ to find the number of packages. Doing that, you get ...
5·0.25 +3·0.10 +2·0.05 = 1.25 +0.30 +0.10 = 1.65
Then 1.65/0.35 ≈ 4.71, so Mae-Ying can buy 4 packages with the money she has.

Answer:
Q = -6
Step-by-step explanation:
To find the answer to this, you first must multiply the first function by 2:
2 x (x - 3y = 4)
2x - 6y = 8
Which then means that the second function is the same. This means that to find Q you need to find the number that changed +Qy into -6:
2x - 6y = 8
2x + Qy = 8
The 2x's cancel out, and then remove the equals and the 8:
-6y = Qy
<h3>So Q must be -6</h3>
