Answer: The variables have a weak positive correlation
Since r > 0, the correlation is positive. It's a weak correlation because r is closer to 0 than it is to 1.

Hello!
Let's solve our equation below.
7p-4=8
First we add 4 to both sides.
7p=12
We divide both sides by 7.
p≈1.71
I hope this helps!
Answer:
The solution is (2, -2)
Step-by-step explanation:
In order to solve this, multiply the second equation by -5 and then add through.
5x - 4y = 18
-5x - 15y = 20
------------------
-19y = 38
y = -2
Now that we have the value of y, we can solve for x.
x + 3y = -4
x + 3(-2) = -4
x - 6 = -4
x = 2
Answer:
1/4
Step-by-step explanation:
First, add up the marbles:
2 + 9 + 7 = 18
Multiply by 2 because you pick two:
18 × 2 = 36
Simplify:
9/36 = 3/12 = 1/4
Hope this helped.
