Answer:
The strong linear relationships are:
r = 0.95
r=-0.83
Step-by-step explanation:
When we have points whit apparent linear tents, we can fit the curve to a line and when the correlation coefficient (r) is equal to 1, we have perfect correlation and when r is equal to 0 we do not have a correlation.
Therefore r = 0.95 suggest strong linear relationships.
Now, we can use the same analysis with a negative value of r, so r = -0.83 is strong too.
I hope it helps you!
Step 1. Use Multiplication Distributive Property
2^2x^2y^2 * -3x^2 * 4y^4
Step 2. Simplify 2^2 to 4
4x^2y^2 * -3x^2 * 4y^4
Step 3. Take out the constants
(4 * -3 * 4)x^2x^2y^2y^4
Step 4. Simplify 4 * -3 * 4 to -48
-48x^2x^2y^2y^4
Step 5. Use product rule: x^a x^b = x^a + b
-48x^2 + 2 y^2 + 4
Step 6. Simplify 2 + 2 to 4
-48x^4y^2 + 4
Step 7. Simplify 2 + 4 to 6
-48x^4y^6
Answer:
84
Step-by-step explanation:
140% of 60 = 60 times 140% = 60 × 1.4 = 84
