X and (4x - 20) are supplementary angles because they add up to 180°. You can tell this because the line which they are formed on is 180<span>°.
Knowing that x + (4x - 20) = 180, you can solve for x:
</span>x + (4x - 20) = 180
(x + 4x) - 20 = 180
5x - 20 = 180
5x = 200
x = 40°

Answer: x = 40°
Answer:
- independent: t
- dependent: d
Step-by-step explanation:
The way the equation is written, d is the dependent variable; t is the independent variable (on which d depends).
Answer:
Scatter plots can be a little confusing, but all you need to do is look for an association (what direction the dots appear to be going in). Positive association resembles this / whereas negative association resembles this / flipped the other way. It could also be a curved line, which would be a nonlinear association. If it appears to have no direction at all it has no association. Other wise, all you have to do is read the data to answer the questions. e.g. for the first question find the highest score in the right side of the table and then the corresponding number in the left side. Hope this helps!
