Answer:
20
Step-by-step explanation:
We have two simultaneous equations.
(1) y = 2x + 50
(2) y = 4.5x
1. Subtract (1) from (2)
0 = 2.5x - 50
2. Add 50 to each side
2.5x = 50
3. Divide each side by 2.5
x = 20

So one key thing to remember here is that the direction of the correlation is irrelevant, that is it does not matter if your correlation is + or - what matters is how close that number is to 1.0.
To help you out here are the ranges of correlation strength
- 0.70. A strong relationship
- 0.50. A moderate relationship
- 0.30. A weak relationship
So to start off with 0.26 and 0.18 are very small correlations so you'd call those weak correlations.
Let me know if you need help doing the other ones? It should be simple enough with the data I gave you :)
Answer:
x≤ −2/3y + −1/3
Step-by-step explanation:
because...
Step 1: Add -4y to both sides.
6x + 4y + −4y ≤ −2+−4y
6x ≤ −4y −2
Step 2: Divide both sides by 6.
6x/6 ≤ 
x ≤ −2/3y + −1/3
Therefor, the answer is x≤ −2/3y + −1/3
