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 :)
Hello,
(tg(x))'=1/cos²(x)
(arcsin(x))'=1/√(1-x²)
cos²(arcsin(x))=1-sin²(arcsin(x))=1-x²
C=2x Pi x R so 2x3.14x17.5 = 109.9
Answer:
Improper Fraction : $22/5
Decimal : $4.4
Mixed: $4 2/5 ...
Step-by-step explanation:
Sherman Has 3 cats and 2 dogs
Sherman has $22 to spend on pet toys.
To find the answer divide the overall amount that Sherman has to spend overall which is $22, Now divide it by the amount of pets that he has, 3+2=5
We can write it as:
Improper Fraction : $22/5
Decimal : $4.4
Mixed: $4 2/5 ....
I hope I’m not too late. Substitute x = 4y + 5y = 2
y = 2. Substitute this value into the first equation: x + -4 x 2 = -8. So the answer is (-8,2).
